Getryl (Glimepiride) 2mg

Getryl (Glimepiride oral tablet)
Highlights for glimepiride
Glimepiride oral tablet is available as a generic drug and as a brand-name drug. Brand name: Amaryl.
Glimepiride comes as a tablet you take by mouth.
Glimepiride is used to treat type 2 diabetes. It helps control blood sugar when used along with a healthy diet and exercise.
What is glimepiride?
Glimepiride is a prescription drug. It comes as an oral tablet.

Glimepiride is available as the brand-name drug Amaryl and as a generic drug. Generic drugs usually cost less. In some cases, they may not be available in every strength or form as the brand-name version.

This drug may be used as part of a combination therapy. That means you need to take it with other drugs.

Why it's used
Glimepiride is used to reduce high blood sugar levels in people with type 2 diabetes. It’s used in combination with a healthy diet and exercise.

This medication may be used with insulin or other types of diabetes drugs to help control your high blood sugar.

How it works
Glimepiride belongs to a class of drugs called sulfonylureas. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

Glimepiride helps your pancreas to release insulin. Insulin is a chemical that your body makes to move sugar (glucose) from your bloodstream into your cells. Once the sugar enters your cells, they can use it as fuel for your body.

With type 2 diabetes, your body doesn’t make enough insulin, or it can't properly use the insulin that it makes, so the sugar stays in your bloodstream. This causes high blood sugar levels (hyperglycemia).

Glimepiride side effects
Glimepiride oral tablet doesn’t cause drowsiness, but it can cause other side effects.

More common side effects
The more common side effects that can occur with glimepiride include:

low blood sugar (hypoglycemia). Symptoms may include:
trembling or shaking
nervousness or anxiety
irritability
sweating
lightheadedness or dizziness
headache
fast heart rate or palpitations
intense hunger
fatigue or tiredness
headache
nausea
dizziness
weakness
unexplained weight gain
If these effects are mild, they may go away within a few days or a couple of weeks. If they’re more severe or don’t go away, talk to your doctor or pharmacist.

Serious side effects
Call your doctor right away if you have serious side effects. Call 911 if your symptoms feel life-threatening or if you think you’re having a medical emergency. Serious side effects and their symptoms can include the following:

severe low blood sugar (less than 35 to 40 mg/dL). Symptoms may include:
mood changes, such as irritability, impatience, anger, stubbornness, or sadness
confusion, including delirium
lightheadedness or dizziness
sleepiness
blurred or impaired vision
tingling or numbness in your lips or tongue
headaches
weakness or fatigue
lack of coordination
nightmares or crying out in your sleep
seizures
unconsciousness
hypersensitivity (allergic) reactions. This drug can cause several types of allergic reactions, including:
anaphylaxis. This is a severe and possibly a life-threatening allergic reaction. Symptoms may include trouble breathing, swelling of your throat or tongue, hives, or difficulty swallowing.
angioedema. This involves swelling of your skin, the layers under your skin, and your mucous membranes (inside your mouth).
Stevens-Johnsons syndrome. This is a rare and serious disorder of your skin and mucous membranes (mouth and nose). It starts with flu-like symptoms and is followed by a painful red rash and blisters.
liver damage. Symptoms may include:
yellowing of your skin and the whites of your eyes (jaundice)
stomach pain and swelling
swelling in your legs and ankles (edema)
itchy skin
dark-colored urine
pale stool or tar-colored stool
constant sleepiness
nausea
vomiting
bruising easily
low blood cell or platelet counts. Symptoms may include infections and bruising or bleeding that doesn’t stop as quickly as normal.
low sodium levels (hyponatremia) and syndrome of inappropriate antidiuretic hormone secretion (SIADH). In SIADH, your body is unable to get rid of excess water by urinating. This leads to lower sodium levels in your blood (hyponatremia), which is dangerous. Symptoms may include:
nausea and vomiting
headache
confusion
loss of energy and fatigue
restlessness and irritability
muscle weakness, spasms, or cramps
seizures
coma

Tonoflex (Tramadol) 50mg

1. Name of the medicinal product
Tramadol hydrochloride/Paracetamol 37.5 mg/325 mg film-coated tablets

2. Qualitative and quantitative composition
Each film-coated tablet contains 37.5 mg tramadol hydrochloride equivalent to 32.94 mg tramadol and 325 mg paracetamol.

For the full list of excipients, see section 6.1.

3. Pharmaceutical form
Film-coated tablet.

Tablets are yellow-brown, oval, slightly biconvex.

4. Clinical particulars
4.1 Therapeutic indications
Tramadol hydrochloride/Paracetamol tablets are indicated for the symptomatic treatment of moderate to severe pain.

The use of Tramadol hydrochloride/Paracetamol should be restricted to patients whose moderate to severe pain is considered to require a combination of tramadol and paracetamol (see also section 5.1).

4.2 Posology and method of administration
Posology

Adults and adolescents (12 years and older)

The use of Tramadol hydrochloride/Paracetamol should be restricted to patients whose moderate to severe pain is considered to require a combination of tramadol and paracetamol.

The dose should be individually adjusted according to intensity of the pain and the sensitivity of the individual patient. The lowest effective dose for analgesia should generally be selected.

An initial dose of two tablets of Tramadol hydrochloride/Paracetamol is recommended. Additional doses can be taken as needed, not exceeding 8 tablets (equivalent to 300 mg tramadol hydrochloride and 2600 mg paracetamol) per day.

The dosing interval should not be less than six hours.

Tramadol hydrochloride/Paracetamol should under no circumstances be administered for longer than is strictly necessary (see also section 4.4.). If repeated use or long term treatment with Tramadol hydrochloride/Paracetamol is required as a result of the nature and severity of the illness, then careful, regular monitoring should take place (with breaks in the treatment, where possible), to assess whether continuation of the treatment is necessary.

Paediatric population

The effective and safe use of Tramadol hydrochloride/Paracetamol has not been established in children below the age of 12 years. Treatment is therefore not recommended in this population.

Elderly patients

A dose adjustment is not usually necessary in patients up to 75 years without clinically manifest hepatic or renal insufficiency. In elderly patients over 75 years elimination may be prolonged. Therefore, if necessary the dosage interval is to be extended according to the patient's requirements.

Renal insufficiency/dialysis

Because of the presence of tramadol, the use of Tramadol hydrochloride/Paracetamol is not recommended in patients with severe renal insufficiency (creatinine clearance < 10 ml/min). In cases of moderate renal insufficiency (creatinine clearance between 10 and 30 ml/min), the dosing should be increased to 12-hourly intervals. As tramadol is removed only very slowly by haemodialysis or by haemofiltration, post dialysis administration to maintain analgesia is not usually required.

Hepatic impairment

In patients with hepatic impairment the elimination of tramadol is delayed. In these patients prolongation of dosage intervals should be carefully considered according to the patient's requirements (see section 4.4).

Because of the presence of paracetamol should not be used in patients with severe hepatic impairment (see section 4.3).

Method of administration

Oral use.

Tablets must be swallowed whole, with a sufficient quantity of liquid. They must not be crushed or chewed.

4.3 Contraindications
Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.

Acute intoxication with alcohol, hypnotic medicinal products, centrally-acting analgesics, opioids or psychotropic medicinal products.

Tramadol hydrochloride/Paracetamol should not be administered to patients who are receiving monoamine oxidase inhibitors or within two weeks of their withdrawal (see section 4.5).

Severe hepatic impairment.

Epilepsy not controlled by treatment (see section 4.4).

4.4 Special warnings and precautions for use
Warnings

- The maximum dose of 8 tablets of Tramadol hydrochloride/Paracetamol should not be exceeded in adults and adolescents 12 years and older. In order to avoid inadvertent overdose, patients should be advised not to exceed the recommended dose and not to use any other paracetamol (including over the counter) or tramadol hydrochloride containing products concurrently without the advice of a physician.

- In severe renal impairment (creatinine clearance <10 ml/min), Tramadol hydrochloride/Paracetamol is not recommended.

- In patients with severe hepatic impairment Tramadol hydrochloride/Paracetamol should not be used (see section 4.3). The hazards of paracetamol overdose are greater in patients with non-cirrhotic alcoholic liver disease. In moderate cases prolongation of dosage interval should be carefully considered.

- In severe respiratory impairment, Tramadol hydrochloride/Paracetamol is not recommended.

- Tramadol is not suitable as a substitute in opioid-dependent patients. Although it is an opioid agonist, tramadol cannot suppress morphine withdrawal symptoms.

- Convulsions have been reported in tramadol-treated patients susceptible to seizures or taking other medications that lower the seizure threshold, especially selective serotonin re-uptake inhibitors, tricyclic antidepressants, antipsychotics, centrally acting analgesics or local anaesthesia. Epileptic patients controlled by a treatment or patients susceptible to seizures should be treated with Tramadol hydrochloride/Paracetamol only if there are compelling circumstances. Convulsions have been reported in patients receiving tramadol at the recommended dose levels. The risk may be increased when doses of tramadol exceed the recommended upper dose limit.

Precautions for use

Tolerance and physical and/or psychological dependence may develop, even at therapeutic doses. The clinical need for analgesic treatment should be reviewed regularly (see 4.2). In opioid-dependent patients and patients with a history of drug abuse or dependence, treatment should only be for short period and under medical supervision.

Tramadol hydrochloride/Paracetamol should be used with caution in patients with cranial trauma, in patients prone to convulsive disorder, biliary tract disorders, in a state of shock, in an altered state of consciousness for unknown reasons, with problems affecting the respiratory centre or the respiratory function, or with an increased intracranial pressure.

Paracetamol overdosage may cause hepatic toxicity in some patients.

Symptoms of withdrawal reactions, similar to those occurring during opiate withdrawal may occur even at therapeutic doses and for short term treatment (see section 4.8). Withdrawal symptoms may be avoided by taper it at the time of discontinuation especially after long treatment periods. Rarely, cases of dependence and abuse have been reported (see section 4.8).

In one study, use of tramadol during general anaesthesia with enflurane and nitrous oxide was reported to enhance intra-operative recall. Until further information is available, use of tramadol during light plans of anaesthesia should be avoided.

4.5 Interaction with other medicinal products and other forms of interaction
Concomitant use is contraindicated with:

- Non-selective MAO Inhibitors

Risk of serotoninergic syndrome: diarrhoea, tachycardia, hyperhidrosis, trembling, confusional state, even coma.

- Selective-A MAO Inhibitors

Extrapolation from non-selective MAO inhibitors, risk of serotoninergic syndrome: diarrhoea, tachycardia, hyperhidrosis, trembling, confusional state, even coma.

- Selective-B MAO Inhibitors

Central excitation symptoms evocative of a serotoninergic syndrome: diarrhoea, tachycardia, hyperhidrosis, trembling, confusional state, even coma.

In case of recent treatment with MAO inhibitors, a delay of two weeks should occur before treatment with tramadol

Concomitant use is not recommended with:

- Alcohol

Alcohol increases the sedative effect of opioid analgesics. The effect on alertness can make driving of vehicles and the use of machines dangerous. Avoid intake of alcoholic drinks and of medicinal products containing alcohol.

- Carbamazepine and other enzyme inducers

Risk of reduced efficacy and shorter duration due to decreased plasma concentrations of tramadol.

- Opioid agonists-antagonists (buprenorphine, nalbuphine, pentazocine)

Decrease of the analgesic effect by competitive blocking effect at the receptors, with the risk of occurrence of withdrawal syndrome.

Concomitant use which needs to be taken into consideration

- Tramadol can induce convulsions and increase the potential for selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, antipsychotics and other seizure threshold-lowering medicinal products (such as bupropion, mirtazapine, tetrahydrocannabinol), to cause convulsions.

- Concomitant therapeutic use of tramadol and serotonergic drugs such as selective serotonin re-uptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), MAO inhibitors (see section 4.3), tricyclic antidepressants and mirtazapine may cause serotonin toxicity. Serotonin syndrome is likely if when one of the following is observed:

- Spontaneous clonus

- Inducible or ocular clonus with, agitation or diaphoresis

- Tremor and hyperreflexia,

- Hypertonia and body temperature >38°C and inducible or ocular clonus.

Withdrawal of the serotonergic drugs usually brings about a rapid improvement. Treatment depends on the type and severity of the symptoms.

- Other opioid derivatives (including antitussive medicinal products and substitutive treatments), benzodiazepines and barbiturates: increased risk of respiratory depression which can be fatal in cases of overdose.

- Other central nervous system depressants, such as other opioid derivatives (including antitussive drugs and substitutive treatments), barbiturates, benzodiazepines, other anxiolytics, hypnotics, sedative antidepressants, sedative antihistamines, neuroleptics, centrally-acting antihypertensive medicinal products, thalidomide and baclofen. These active substances can cause increased central depression. The effect on alertness can make driving of vehicles and the use of machines dangerous.

- Caution should be exercised during concomitant treatment with Tramadol hydrochloride/Paracetamol and coumarin derivatives (e.g. warfarin) due to reports of increased INR with major bleeding and ecchymoses in some patients.

- Other drugs known to inhibit CYP3A4, such as ketoconazole and erythromycin, might inhibit the metabolism of tramadol (N-demethylation) probably also the metabolism of the active O-demethylated metabolite. The clinical importance of such an interaction has not been studied.

- In a limited number of studies the pre- or postoperative application of the antiemetic 5-HT3 antagonist ondansetron increased the requirement of tramadol in patients with postoperative pain.

4.6 Fertility, pregnancy and lactation
Pregnancy

Since Tramadol hydrochloride/Paracetamol is a fixed combination of active ingredients including tramadol, it should not be used during pregnancy.

Data regarding paracetamol:

Epidemiological studies in human pregnancy have shown no ill effects due to paracetamol used in the recommended dosage.

Data regarding tramadol:

Tramadol should not be used during pregnancy as there is inadequate evidence available to assess the safety of tramadol in pregnant women. Tramadol administered before or during birth does not affect uterine contractility. In neonates it may induce changes in the respiratory rate which are usually not clinically relevant. Long-term treatment during pregnancy may lead to withdrawal symptoms in the newborn after birth, as a consequence of habituation.

Breast-feeding

Since Tramadol hydrochloride/Paracetamol is a fixed combination of active ingredients including tramadol, it should not be used more than once during breast feeding or alternatively, breast-feeding should be discontinued during treatment with tramadol.

Data regarding paracetamol:

Paracetamol is excreted in breast milk but not in a clinically significant amount. Available published data on paracetamol does not contraindicate it for breast feeding by women using single ingredient medicinal products containing only paracetamol.

Data regarding tramadol:

Approximately 0.1% of the maternal dose of tramadol is excreted in breast milk. In the immediate post-partum period, for maternal oral daily dosage up to 400 mg, this corresponds to a mean amount of tramadol ingested by breast-fed infants of 3% of the maternal weight-adjusted dosage. For this reason tramadol should not be used during lactation or alternatively, breast-feeding should be discontinued during treatment with tramadol. Discontinuation of breast-feeding is generally not necessary following a single dose of tramadol.

Fertility

Post marketing surveillance does not suggest an effect of tramadol on fertility.

Animal studies did not show an effect of tramadol on fertility. No study on fertility was accomplished with the combination of tramadol and paracetamol.

4.7 Effects on ability to drive and use machines
Tramadol hydrochloride may cause drowsiness or dizziness, which may be enhanced by alcohol or other CNS depressants. If affected, the patient should not drive or operate machinery.

4.8 Undesirable effects
Undesirable effects that may occur during treatment with Tramadol hydrochloride/Paracetamol are classified into the following groups in order of frequency:

- very common (≥1/10)

- common (≥1/100 to <1/10)

- uncommon (≥1/1,000 to <1/100)

- rare (≥1/10,000 to <1/1,000)

- very rare (<1/10,000)

- not known (cannot be estimated from the available data)

Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

The most commonly reported undesirable effects during the clinical trials performed with the paracetamol/tramadol combination were nausea, dizziness and somnolence, observed in more than 10% of the patients.

*Reported in post marketing surveillance.

Although not observed during clinical trials, the occurrence of the following undesirable effects known to be related to the administration of tramadol or paracetamol cannot be excluded:

Tramadol

- Postural hypotension, bradycardia, collapse (tramadol).

- Post-marketing surveillance of tramadol has revealed rare alterations of warfarin effect, including elevation of prothrombin times.

- Rare cases: allergic reactions with respiratory symptoms (e.g. dyspnoea, bronchospasm, wheezing, angioneurotic oedema) and anaphylaxis.

- Rare cases: changes in appetite, motor weakness, and respiratory depression.

- Psychic side-effects may occur following administration of tramadol which vary individually in intensity and nature (depending on personality and duration of medication). These include changes in mood, (usually elation occasionally dysphoria), changes in activity (usually suppression occasionally increase) and changes in cognitive and sensorial capacity (e.g. decision behaviour perception disorders).

- Worsening of asthma has been reported though a causal relationship has not been established.

- Symptoms of withdrawal reactions, similar to those occurring during opiate withdrawal may occur as follows: agitation, anxiety, nervousness, insomnia, hyperkinesia, tremor and gastrointestinal symptoms. Other symptoms that have very rarely been seen if tramadol hydrochloride is discontinued abruptly include: panic attacks, severe anxiety, hallucinations, paraesthesia, tinnitus and unusual CNS symptoms.

Paracetamol

- Adverse effects of paracetamol are rare but hypersensitivity including skin rash may occur. There have been reports of blood dyscrasias including thrombocytopenia and agranulocytosis, but these were not necessarily causally related to paracetamol.

- There have been several reports that suggest that paracetamol may produce hypoprothrombinemia when administered with warfarin-like compounds. In other studies, prothrombin time did not change.

- Very rare cases of serious skin reactions have been reported.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard.

4.9 Overdose
Tramadol hydrochloride/Paracetamol is a fixed combination of active ingredients. In case of overdose, the symptoms may include the signs and symptoms of toxicity of tramadol or paracetamol or of both these active ingredients.

Symptoms of overdose from tramadol

In principle, on intoxication with tramadol, symptoms similar to those of other centrally acting analgesics (opioids) are to be expected. These include in particular, miosis, vomiting, cardiovascular collapse, consciousness disorders up to coma, convulsions and respiratory depression up to respiratory arrest.

Symptoms of overdose from paracetamol

An overdose is of particular concern in young children. Symptoms of paracetamol overdosage in the first 24 hours are pallor, nausea, vomiting, anorexia and abdominal pain. Liver damage may become apparent 12 to 48 hours after ingestion. Abnormalities of glucose metabolism and metabolic acidosis may occur. In severe poisoning, hepatic failure may progress to encephalophathy, coma and death. Acute renal failure with acute tubular necrosis may develop even in the absence of severe liver damage. Cardiac arrhythmias and pancreatitis have been reported.

Liver damage is possible in adults who have taken 7.5-10 g or more of paracetamol. It is considered that excess quantities of a toxic metabolite (usually adequately detoxified by glutathione when normal doses of paracetamol are ingested), become irreversibly bound to liver tissue.

Emergency treatment

- Transfer immediately to a specialised unit.

- Maintain respiratory and circulatory functions.

- Prior to starting treatment, a blood sample should be taken as soon as possible after overdose in order to measure the plasma concentration of paracetamol and tramadol and in order to perform hepatic tests.

- Perform hepatic tests at the start (of overdose) and repeat every 24 hours. An increase in hepatic enzymes (ASAT, ALAT) is usually observed, which normalizes after one or two weeks.

- Empty the stomach by causing the patient to vomit (when the patient is conscious) by irritation or gastric lavage.

- Supportive measures such as maintaining the patency of the airway and maintaining cardiovascular function should be instituted; naloxone should be used to reverse respiratory depression; fits can be controlled with diazepam.

- Tramadol is minimally eliminated from the serum by haemodialysis or haemofiltration. Therefore treatment of acute intoxication with Tramadol hydrochloride/Paracetamol with haemodialysis or haemofiltration alone is not suitable for detoxification.

Immediate treatment is essential in the management of paracetamol overdose. Despite a lack of significant early symptoms, patients should be referred to hospital urgently for immediate medical attention and any adult or adolescent who had ingested around 7.5 g or more of paracetamol in the preceding 4 hours or any child who has ingested ≥150 mg/kg of paracetamol in the preceding 4 hours should undergo gastric lavage. Paracetamol concentrations in blood should be measured later than 4 hours after overdose in order to be able to assess the risk of developing liver damage (via the paracetamol overdose nomogram). Administration of oral methionine or intravenous N-acetylcysteine (NAC) which may have a beneficial effect up to at least 48 hours after the overdose, may be required. Administration of intravenous N-acetylcysteine (NAC) is most beneficial when initiated within 8 hours of overdose ingestion. However, NAC should still be given if the time to presentation is greater than 8 hours after overdose and continued for a full course of therapy. NAC treatment should be started immediately when massive overdose is suspected. General supportive measures must be available.

Irrespective of the reported quantity of paracetamol ingested, the antidote for paracetamol, NAC, should be administered orally or intravenously, as quickly as possible, if possible, within 8 hours following the overdose.

5. Pharmacological properties
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: other opioids, tramadol, combinations, ATC code: N02AX52.

Analgesics

Tramadol is an opioid analgesic that acts on the central nervous system. Tramadol is pure non selective agonists of the μ, δ, and κ opioid receptors with a higher affinity for the µ receptors. Other mechanisms which contribute to its analgesic effect are inhibition of neuronal reuptake of noradrenaline and enhancement of serotonin release. Tramadol has an antitussive effect. Unlike morphine, a broad range of analgesic doses of tramadol has no respiratory depressant effect. Similarly, the gastro-intestinal motility is not modified. The cardiovascular effects are generally slight. The potency of tramadol is considered to be one-tenth to one-sixth that of morphine.

Mechanism of action

The precise mechanism of the analgesic properties of paracetamol is unknown and may involve central and peripheral effects.

Tramadol hydrochloride/Paracetamol is positioned as a step II analgesic in the WHO pain ladder and should be utilised accordingly by the physician.

5.2 Pharmacokinetic properties
Tramadol is administered in racemic form and the [-] and [+] forms of tramadol and its metabolite M1, are detected in the blood. Although tramadol is rapidly absorbed after administration, its absorption is slower (and its half-life longer) than that of paracetamol.

After a single oral administration of a tramadol/paracetamol (37.5 mg/325 mg) tablet, peak plasma concentrations of 64.3/55.5 ng/ml [(+)-tramadol/(-)-tramadol] and 4.2 µg/ml (paracetamol) are reached after 1.8 h [(+)-tramadol/(-)-tramadol] and 0.9 h (paracetamol) respectively. The mean elimination half-lives t1/2 are 5.1/4.7 h [(+)-tramadol/(-)-tramadol] and 2,5 h (paracetamol).

During pharmacokinetic studies in healthy volunteers after single and repeated oral administration of Tramadol hydrochloride/Paracetamol, no clinical significant change was observed in the kinetic parameters of each active ingredient compared to the parameters of the active ingredients used alone.

Absorption

Racemic tramadol is rapidly and almost completely absorbed after oral administration. The mean absolute bioavailability of a single 100 mg dose is approximately 75%. After repeated administration, the bioavailability is increased and reaches approximately 90%.

After administration of Tramadol hydrochloride/Paracetamol, the oral absorption of paracetamol is rapid and nearly complete and takes place mainly in the small intestine. Peak plasma concentrations of paracetamol are reached in one hour and are not modified by concomitant administration of tramadol.

The oral administration of Tramadol hydrochloride/Paracetamol with food has no significant effect on the peak plasma concentration or extent of absorption of either tramadol or paracetamol so that Tramadol hydrochloride/Paracetamol can be taken independently of meal times.

Distribution

Tramadol has a high tissue affinity (Vd,β=203 ± 40 l). It has a plasma protein binding of about 20%.

Paracetamol appears to be widely distributed throughout most body tissues except fat. Its apparent volume of distribution is about 0.9 l/kg. A relative small portion (~20%) of paracetamol is bound to plasma proteins.

Biotransformation

Tramadol is extensively metabolized after oral administration. About 30% of the dose is excreted in urine as unchanged drug, whereas 60% of the dose is excreted as metabolites.

Tramadol is metabolised through O-demethylation (catalysed by the enzyme CYP2D6) to the metabolite M1, and through N-demethylation (catalysed by CYP3A) to the metabolite M2. M1 is further metabolised through N-demethylation and by conjugation with glucuronic acid. The plasma elimination half-life of M1 is 7 hours. The metabolite M1 has analgesic properties and is more potent than the parent drug. The plasma concentrations of M1 are several-fold lower than those of tramadol and the contribution to the clinical effect are unlikely to change on multiple dosing.

Paracetamol is principally metabolized in the liver through two major hepatic routes: glucuronidation and sulphation. The latter route can be rapidly saturated at doses above the therapeutic doses. A small fraction (less than 4%) is metabolized by cytochrome P450 to an active intermediate (the N-acetyl benzoquinoneimine) which, under normal conditions of use, is rapidly detoxified by reduced glutathione and excreted in urine after conjugation to cysteine and mercapturic acid. However, during massive overdose, the quantity of this metabolite is increased.

Elimination

Tramadol and its metabolites are eliminated mainly by the kidneys.

The half-life of paracetamol is approximately 2 to 3 hours in adults. It is shorter in children and slightly longer in the newborn and in cirrhotic patients. Paracetamol is mainly eliminated by dose-dependent formation of glucuro- and sulpho-conjugate derivatives. Less than 9% of paracetamol is excreted unchanged in urine. In renal insufficiency, the half-life of both compounds is prolonged.

5.3 Preclinical safety data
No preclinical study has been performed with the fixed combination (tramadol and paracetamol) to evaluate its carcinogenic or mutagenic effects or its effects on fertility.

No teratogenic effect that can be attributed to the medicine has been observed in the progeny of rats treated orally with the combination tramadol/paracetamol.

The combination tramadol/paracetamol has proven to be embryotoxic and foetotoxic in the rat at materno-toxic dose (50/434 mg/kg tramadol/paracetamol), i.e., 8.3 times the maximum therapeutic dose in man. No teratogenic effect has been observed at this dose. The toxicity to the embryo and the foetus results in a decreased foetal weight and an increase in supernumerary ribs. Lower doses, causing less severe materno-toxic effect (10/87 and 25/217 mg/kg tramadol/paracetamol) did not result in toxic effects in the embryo or the foetus.

Results of standard mutagenicity tests did not reveal a potential genotoxic risk for tramadol in man.

Results of carcinogenicity tests do not suggest a potential risk of tramadol for man.

Animal studies with tramadol revealed, at very high doses, effects on organ development, ossification and neonatal mortality, associated with maternotoxicity. Fertility reproductive performance and development of offspring were unaffected. Tramadol crosses the placenta. No effect on fertility has been observed after oral administration of tramadol up to doses of 50 mg/kg in the male rat and 75 mg/kg in the female rat.

Extensive investigations showed no evidence of a relevant genotoxic risk of paracetamol at therapeutic (i.e. non-toxic) doses.

Long-term studies in rats and mice yielded no evidence of relevant tumorigenic effects at non-hepatotoxic dosages of paracetamol.

Animal studies and extensive human experience to date yield no evidence of reproductive toxicity.

Opinor 0.3mg

OPINOR 0.3mg
Generic Name: Buprenorphine
Buprenorphine is used to treat opioid dependence (addiction to opioid drugs, including heroin and narcotic painkillers). Buprenorphine is in a class of medications called opioid partial agonist-antagonists, and naloxone is in a class of medications called opioid antagonists. Buprenorphine alone and the combination of buprenorphine and naloxone prevent withdrawal symptoms when someone stops taking opioid drugs by producing similar effects to these drugs.

How should this medicine be used?
Buprenorphine and the combination of buprenorphine and naloxone come as sublingual tablets to taken under the tongue. They are usually taken once a day. To help you remember to take buprenorphine or buprenorphine and naloxone, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take buprenorphine or buprenorphine and naloxone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
You will start your treatment with buprenorphine, which you will take in the doctor’s office. Your doctor will start you on a low dose of buprenorphine and will increase your dose for several days before switching you to buprenorphine and naloxone. Your doctor may increase or decrease your buprenorphine and naloxone dose until the medication works properly.
Place the tablets under your tongue until they melt. This should take 2 to 10 minutes. If you are taking more than two tablets, either place them all under your tongue at the same time or place them under your tongue 2 at a time. Do not chew the tablets or swallow them whole.
Do not stop taking buprenorphine and naloxone without talking to your doctor. Stopping buprenorphine and naloxone too quickly can cause withdrawal symptoms. Your doctor will tell you when and how to stop taking buprenorphine and naloxone.
Before taking buprenorphine:
  • Tell your doctor and pharmacist if you are allergic to buprenorphine, naloxone, or any other medications.
  • Do not take antidepressants (‘mood elevators’), narcotic pain killers, sedatives, sleeping pills, or tranquilizers while taking buprenorphine or buprenorphine and naloxone.
  • Tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: acetaminophen (Tylenol, others); antifungals such as fluconazole (Diflucan), itraconazole (Sporanox), and ketoconazole (Nizoral); carbamazepine (Tegretol); cholesterol-lowering medications (statins); cimetidine (Tagamet); clarithromycin (Biaxin); cyclosporine (Neoral, Sandimmune); danazol (Danocrine); delavirdine (Rescriptor); dexamethasone (Decadron); diltiazem (Cardizem, Dilacor, Tiazac); erythromycin (E.E.S., E-Mycin, Erythrocin); ethosuximide (Zarontin);fluoxetine (Prozac, Sarafem); fluvoxamine (Luvox); HIV protease inhibitors such as indinavir (Crixivan), nelfinavir (Viracept), and ritonavir (Norvir); iron products; isoniazid (INH, Nydrazid); medications for anxiety, mental illness, and seizures; methotrexate (Rheumatrex); metronidazole (Flagyl);nefazodone (Serzone); niacin (nicotinic acid); oral contraceptives (birth control pills); phenobarbital (Luminal, Solfoton); phenytoin (Dilantin); rifabutin (Mycobutin); rifampin (Rifadin, Rimactane); troglitazone (Rezulin); troleandomycin (TAO); verapamil (Calan, Covera, Isoptin, Verelan); and zafirlukast (Accolate). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • Tell your doctor if you drink large amounts of alcohol and if you have or have ever had adrenal problems such as Addison’s disease; benign prostatic hypertrophy (BPH, enlargement of the prostate gland); difficulty urinating; head injury; hallucinations (seeing things or hearing voices that do not exist); a curve in the spine that makes it hard to breathe; gallbladder disease; stomach conditions; and thyroid, kidney, liver, or lung disease.
  • Tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking buprenorphine or buprenorphine and naloxone, call your doctor.
  • If you are having surgery, including dental surgery, tell the doctor or dentist that you are taking buprenorphine or buprenorphine and naloxone.
  • You should know that buprenorphine or buprenorphine and naloxone may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
  • Remember that alcohol can add to the breathing difficulties that can be caused by this medication.
  • You should know that buprenorphine or buprenorphine and naloxone may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start taking buprenorphine or buprenorphine and naloxone. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.

6. Contents of the pack and other information

1. What is Pregnyl and what is it used for?

Pregnyl belongs to a group of medicines called gonadotrophins (sex hormones). It controls the release of eggs from the ovary in women, and controls production of the male hormone, testosterone in men.

Women

In female infertility it can be used to cause women to ovulate (Ovulation induction). Pregnyl is also used along with other fertility drugs, to help produce eggs in medically assisted reproduction programmes (IVF treatment).

Men

In men it is used to help treat delayed puberty, undescended testes or oligospermia (low sperm count).

Ask your doctor if you are unsure why you have been given Pregnyl.

2. When should you not use this medicine or when should you be extra careful with this medicine?

When should you not use this medicine?

If you are allergic (hypersensitive) to human chorionic gonadotrophin (hCG) or any of the other ingredients of this medicine (listed in section 6).
If you have a thyroid, adrenal or pituitary illness which is not being treated.
If you have cancer, (especially a hormone-dependent cancer of the breast, ovaries or womb).
If you have recently had unexplained vaginal bleeding which is not related to your menstrual period.
If you have fibroids in the womb or abnormalities of the reproductive organs which make a normal pregnancy impossible.
If you are a man and have, or suspect you have a hormone-related tumour, such as testicular, prostate or breast cancer.
When should you be extra careful with this medicine?

Medicines are not always suitable for everyone.

Talk to your doctor before using Pregnyl if you suffer from or have suffered in the past from any of the following conditions:

abnormalities of the reproductive organs. Before treatment with Pregnyl your doctor should have checked that your reproductive organs are normal
in women patients your doctor should have checked how your ovaries are working before starting treatment with Pregnyl. Extra supervision may be necessary in some cases.
uncontrolled pituitary gland or hypothalamic problems.
underactive thyroid gland (hypothyroidism).
adrenal glands that are not working properly (adrenocortical insufficiency).
high prolactin levels in the blood (hyperprolactinaemia).
any other medical conditions (for example, diabetes, heart disease, or any other long-term disease).
Allergic reactions

Allergic reactions, both generalised and local, including swelling of the face, lips, tongue, and/or throat that may cause difficulty in breathing or swallowing (angioedema and anaphylaxis) have been reported. If you have an allergic reaction, stop taking Pregnyl and seek immediate medical assistance (See also section 4. Possible side effects).

Misuse for weight control

Pregnyl must not be used for weight loss. HCG has no effect on fat metabolism (burning fat), distribution of fat or appetite.

For women:

Chance of having ovarian hyperstimulation syndrome (OHSS)

Treatment with gonadotropic hormones like Pregnyl may cause ovarian hyperstimulation syndrome (OHSS). This is a serious medical condition where the ovaries are overly stimulated and the growing follicles become larger than normal. In rare cases, severe OHSS may be life-threatening. Therefore, close supervision by your doctor is very important. To check the effects of treatment, your doctor will do ultrasound scans of your ovaries. Your doctor may also check blood hormone levels (See also section 4. Possible side effects).

OHSS causes fluid to build up suddenly in your stomach and chest areas and can cause blood clots to form. Call your doctor right away if you have:

severe abdominal swelling and pain in the stomach area (abdomen)
feeling sick (nausea)
vomiting
sudden weight gain due to fluid build-up
diarrhoea
decreased urine output
trouble breathing
Ovarian Torsion

Ovarian torsion is the twisting of an ovary. Twisting of the ovary could cause the blood flow to the ovary to be cut off.

Before starting to use this medicine, it is important to inform your doctor if you:

have ever had ovarian hyperstimulation syndrome OHSS
are pregnant or think that you may be pregnant
have ever had stomach (abdominal) surgery
have ever had a twisting of an ovary
have past or current cysts in your ovary or ovaries
Chance of having a blood clot (thrombosis)

Being pregnant increases the chance of having a blood clot.

If you have risks factors for having a blood clot (for example being overweight, or if blood clots run in your family), the chance of having a blood clot in a blood vessel (thrombosis) may be increased during IVF treatment.

Blood clots can lead to serious medical conditions, such as:

blockage in your lungs (pulmonary embolus)
stroke
heart attack
reduced blood flow to the vital organs that may result in organ damage
reduced blood flow (deep vein thrombosis) to your arm or leg that may result in a loss of your arm or leg.
Please discuss this with your doctor, before starting treatment, especially if:

you already know you have an increased risk of blood clots
you, or anyone in your immediate family, have ever had a blood clot
you are severely overweight.
Chance of having multiple births, birth defects, miscarriage or pregnancy complications

If treatment with Pregnyl results in pregnancy, there is an increased chance having twins or multiple births. Multiple pregnancies carry an increased health risk for both the mother and her babies around the time of birth. In women undergoing fertility treatment there is a slightly increased risk of a miscarriage, or a pregnancy outside of the uterus (an ectopic pregnancy). Therefore, your doctor should perform an early ultrasound examination to exclude the possibility of pregnancy outside the uterus.

It is unknown if IVF treatment causes congenital malformations, or some cancers of the sex organs.

For men:

Talk to your doctor before using Pregnyl if you suffer from or have suffered in the past from any of the following conditions:

heart problems
kidney problems
high blood pressure
epilepsy
migraine
Antibody formation

If the treatment with Pregnyl is not working, consult with your doctor who may perform additional tests.

Treatment with Pregnyl (hCG) can cause the body to produce substances that act against hCG (antibodies to hCG). In rare cases this could result in ineffective treatment.

Children and adolescents

Pregnyl should be used carefully when treating boys who have not reached puberty. This is because it can cause early sexual development and may result in final adult height not being reached.

Other medicines and Pregnyl

Some medicines can affect the way Pregnyl works, or Pregnyl may affect how other medicines work. For up to ten days after administration, Pregnyl may result in a false-positive pregnancy test. In case of a positive pregnancy test, contact your doctor.

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
3. How to use this medicine

Always take this medicine exactly as described in this leaflet or as your doctor, pharmacist or nurse has told you. Check with your doctor, pharmacist or nurse if you are not sure.

Your doctor will choose the most suitable starting dose for you. The usual starting doses for men and women are as follows:

Women

Patients undergoing ovulation induction:

5,000–10,000 I.U. Pregnyl following treatment with other fertility drugs.

2 to 3 repeat injections of 1,000 to 3,000 I.U. each may be given within the following 9 days.

Patients undergoing IVF treatment:

5,000–10,000 I.U. Pregnyl 30–40 hours after the last injection of other fertility drugs.

Men

In male patients injections are given 2 to 3 times a week for some weeks or months, depending on the problem. Because the development of sperm cells takes about 74 days, treatment should be continued for at least three months before any improvement can be expected.

How are the injections given?

The very first injection of Pregnyl should only be given under medical supervision.

Injections may be given slowly into a muscle (for instance in the bottom, upper leg or upper arm) or under the skin (in the stomach wall, for example).

When given into a muscle the injection should be given by the doctor or nurse. The best site for injection of Pregnyl is the muscle of your bottom. The upper outside quarter of your bottom cheek contains a large amount of muscle with few blood vessels or major nerves.

When given under the skin the injection may, in some cases, be given by yourself or your partner. Your doctor will tell you when and how to do this. If you inject yourself with Pregnyl, follow the instructions on this leaflet carefully to give Pregnyl properly and with minimal discomfort.

Step 1 - Preparing Pregnyl

Pregnyl comes in two glass ampoules whose contents must be mixed together and used immediately.

First, break the top off the ampoule with the sodium chloride solution (a).

Draw up the liquid through the larger needle into the syringe (b).

Break open the second ampoule containing the dry white powder (c) and add the sodium chloride solution from the syringe (d).

Do not shake, but gently swirl until the solution is clear. The Pregnyl usually dissolves immediately.

If the solution contains particles or does not become clear, do not use it.

Draw the Pregnyl solution up into the empty syringe (e), and now replace the needle with a smaller sterile injection needle (f). Finally hold the syringe with the needle pointing upwards and gently tap the side to force any air bubbles up to the top; then squeeze the plunger until all the air has been expelled, and only Pregnyl solution is left in the syringe (g).

Step 2 - The injection site

The best site for injection is in the stomach around the middle of the tummy (h) where there is a lot of loose skin and layers of fatty tissue. Pinch up a large area of skin between the finger and thumb. You should change the injection site a little each time you inject. It is possible to inject in other areas. Your doctor or nurse will advise you where to inject.

Step 3 - Preparing the area

A few taps at the injection site will stimulate tiny nerve endings and help reduce discomfort when the needle goes in. Hands should be washed and the injection site swabbed with disinfectant (for example chlorohexidine 0.5%) to remove any surface bacteria. Clean about two inches around the point where the needle will go in and let the disinfectant dry for at least one minute before proceeding.

Step 4 - Inserting the needle

The needle should be inserted at the base of the pinched-up skin at an angle of 45° to the skin surface (i).

Step 5 - Checking the correct needle position

If the needle position is correct the plunger should be quite difficult to draw back. Any blood sucked back into the syringe means that the needle tip has entered a vein or artery. If this happens pull out the syringe, cover the injection site with a swab containing disinfectant and apply pressure; the site will stop bleeding in a minute or two. Do not use this solution but flush it away.

Start again with Step 1 using a new needle and new ampoules of Pregnyl and sodium chloride solution.

Step 6 - Injecting the solution

Depress the syringe plunger slowly and steadily, so the solution is correctly injected and the muscle or skin tissues are not damaged.

Step 7 - Removing the syringe

Pull the syringe out quickly and apply pressure to the injection site with a swab containing disinfectant. A gentle massage of the site - while still maintaining pressure - helps disperse the Pregnyl solution and relieve any discomfort. Any remaining solution should be discarded. Do not mix Pregnyl solution with any other medicines.

Step 8 - Disposing of needles

Replace the needle guard on the syringe to prevent injury.

Carefully dispose of any needles that you use.

You can dispose of needles in a ‘sharps bin’, or take them to your local pharmacy for disposal. Do not share your needles or syringes.

Always take Pregnyl exactly as your doctor has told you. Check with your doctor or pharmacist if you are still not sure.

If you take more Pregnyl than you should

As your doctor will be keeping a close eye on you it is unlikely you will be given too much, however too high a dose of Pregnyl may cause hyperstimulation of the ovaries. This may be noticed as pain in the abdomen. See section on Possible side effects below. If you are troubled by stomach pains, tell your doctor immediately.

If you accidentally use too much Pregnyl contact your doctor at once or go to the nearest hospital casualty department. Always take the labelled medicine package with you, whether there is any Pregnyl left or not.

If you forget to take Pregnyl

If you forget to take a dose do not take a double dose to make up for a missed dose.

Contact your doctor.
If you stop taking Pregnyl

Do not stop taking Pregnyl unless your doctor tells you to. Your doctor will advise you if you need to stop using Pregnyl for any reason.

If you have any further questions on how to take Pregnyl, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Serious side effects: tell a doctor straight away

If you have an allergic reaction to Pregnyl see a doctor straight away

Pregnyl may cause reactions at the site of injection, such as bruising, pain, redness, swelling and rashes at the injection site.
more widespread rash and fever may occur (see section 2 “When should you be extra careful with this medicine?”).
Contact a doctor immediately if you are a woman and experience:

Severe pain in the abdomen, feeling sick (nausea), diarrhoea, painful breasts, also if it occurs a few days after you receive your last injection, since it could be a sign of unwanted overstimulation of the ovaries (OHSS).

If you are a woman:

A possible complication of treatment with gonadotropic hormones like Pregnyl is unwanted overstimulation of the ovaries. The chance of having this complication can be reduced by carefully monitoring the number of maturing follicles (small round sacs in your ovaries that contain the eggs). Your doctor will do ultrasound scans of your ovaries to carefully monitor the number of maturing follicles. Your doctor may also check blood hormone levels. The first symptoms of ovarian overstimulation may be noticed as pain in the stomach (abdomen), feeling sick or diarrhoea. Ovarian overstimulation may develop into a medical condition called ovarian hyperstimulation syndrome (OHSS), which can be a serious medical problem. In more severe cases this may lead to enlargement of the ovaries, collection of fluid in the abdomen and/or chest (which may cause sudden weight gain due to fluid build-up) or clots in the blood vessels (See also Section 2 When should you be extra careful with this medicine?).

Contact your doctor without delay if you have pain in the stomach (abdomen) or any of the other symptoms of ovarian hyperstimulation, even if they occur some days after Pregnyl has been given.
If you are a man:

fluid may be retained in the tissues, usually marked by swelling of ankles or feet, and occasionally enlargement of the breast may occur. This can be caused by an increased androgen production by treatment with hCG.
If any of these signs appear, tell your doctor immediately.
Other possible side effects

acne (in men)
fluid retention
headache
tiredness
mood changes
Reporting of side effects

If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store. By reporting side effects you can help provide more information on the safety of this medicine.

Ketasol 100mg/2ml

Ketamine is a drug used in human and veterinary medicine. Ketamine is primarily used for the induction and maintenance of general anesthesia, usually in combination with a sedative. Other uses include sedation in intensive care, analgesia (particularly in emergency medicine), and treatment of bronchospasm. Ketamine has a wide range of effects in humans, including analgesia, anesthesia, hallucinations, elevated blood pressure, and bronchodilation.



It has been shown to be effective in treating depression in patients with bipolar disorderwho have not responded to anti-depressants. In persons with major depressive disorder, it produces a rapid antidepressant effect, acting within two hours as opposed to the several weeks taken by typical antidepressants to work. It is also a popular anesthetic inveterinary medicine.
Its hydrochloride salt is sold as Ketanest, Ketaset, and Ketalar. Pharmacologically, ketamine is classified as an NMDA receptor antagonist. At high, fully anesthetic level doses, ketamine has also been found to bind to opioid μ receptors type 2 in cultured human neuroblastoma cells – however, without agonist activity – and to sigma receptorsin rats. Also, ketamine interacts with muscarinic receptors, descending monoaminergic pain pathways and voltage-gated calcium channels. Like other drugs of this class such as tiletamine and phencyclidine (PCP), it induces a state referred to as “dissociative anesthesia” and is used as a recreational drug.
Ketamine is a chiral compound. Most pharmaceutical preparations of ketamine areracemic; however, some brands reportedly have (mostly undocumented) differences inenantiomeric proportions. The more active enantiomer, (S)-ketamine, is also available for medical use under the brand name Ketanest S. Ketamine is a core medicine in theWorld Health Organization’s “Essential Drugs List”, a list of minimum medical needs for a basic healthcare system.

Medicinal Use
One 10ml vial of 1000mg Ketamine
Indications for use as an anaesthetic:

Pediatric anesthesia (as the sole anesthetic for minor procedures or as an induction agent followed by muscle relaxant and endotracheal intubation)
Asthmatics or patients with chronic obstructive airway disease
As part of a cream, gel, or liquid for topical application for nerve pain — the most common mixture is 10% ketoprofen, 5% Lidocaine, and 10% ketamine. Other ingredients found useful by pain specialists and their patients as well as the compounding pharmacists who make the topical mixtures include amitriptyline,cyclobenzaprine, clonidine, tramadol, and mepivicaine and other longer-acting local anaesthetics.
In emergency medicine if entrapped patient is suffering severe trauma
Emergency surgery in field conditions in war zones
To supplement spinal / epidural anesthesia / analgesia utilizing low doses
In medical settings, ketamine is usually injected intravenously or intramuscularly. Since it suppresses breathing much less than most other available anaesthetics, ketamine is still used in human medicine as an anesthetic; however, due to the hallucinations which may be caused by ketamine, it is not typically used as a primary anesthetic, although it is the anaesthetic of choice when reliable ventilation equipment is not available. Ketamine tends to increase heart rate and blood pressure. Because ketamine tends to increase or maintain cardiac output, it is sometimes used in anesthesia for emergency surgery when the patient’s fluid volume status is unknown (e.g., from traffic accidents). Ketamine can be used in podiatry and other minor surgery, and occasionally for the treatment of migraine. There is ongoing research in France, the Netherlands, Russia, Australia and the US into the drug’s usefulness in pain therapy, depression, and for the treatment ofalcoholism and heroin addiction.
In veterinary anesthesia, ketamine is often used for its anesthetic and analgesic effects on cats, dogs, rabbits, rats, and other small animals. Veterinarians often use ketamine with sedative drugs to produce balanced anesthesia and analgesia, and as a constant rate infusion to help prevent pain wind-up. Ketamine is used to manage pain among large animals, though it has less effect on bovines. It is the primary intravenous anesthetic agent used in equine surgery, often in conjunction with detomidine and thiopental, or sometimesguaifenesin.
Ketamine may be used in small doses (0.1–0.5 mg/kg·h) as a local anesthetic, particularly for the treatment of pain associated with movement and neuropathic pain. It may also be used as an intravenous co-analgesic together with opiates to manage otherwise intractable pain, particularly if this pain is neuropathic (pain due to vascular insufficiency or shingles are good examples). It has the added benefit of counter-acting spinal sensitization or wind-up phenomena experienced with chronic pain. At these doses, the psychotropic side effects are less apparent and well managed with benzodiazepines. Ketamine is a co-analgesic, and so is most effective when used alongside a low-dose opioid; while it does have analgesic effects by itself, the higher doses required can cause disorienting side effects. The combination of ketamine with an opioid is, however, particularly useful for pain caused by cancer.
The effect of ketamine on the respiratory and circulatory systems is different from that of other anesthetics. When used at anesthetic doses, it will usually stimulate rather than depress the circulatory system. It is sometimes possible to perform ketamine anesthesia without protective measures to the airways. Ketamine is also a potent analgesic and can be used in sub-anesthetic doses to relieve acute pain; however, its psychotropic properties must be taken into account. Patients have reported vivid hallucinations, “going into other worlds” or “seeing God” while anesthetized, and these unwanted psychological side-effects have reduced the use of ketamine in human medicine. They can, however, usually be avoided by concomitant application of a sedative such as a benzodiazepine.
Low-dose ketamine is recognized for its potential effectiveness in the treatment of complex regional pain syndrome (CRPS), according to a retrospective review published in the October 2004 issue of Pain Medicine.Although low-dose ketamine therapy is established as a generally safe procedure, reported side effects in some patients have included hallucinations, dizziness, lightheadedness and nausea. Therefore nurses administering ketamine to patients with CRPS should do so only in a setting where a trained physician is available if needed to assess potential adverse effects on patients.
In some neurological ICUs, ketamine has been used in cases of prolonged seizures. There has been some evidence that the NMDA-blocking effect of the drug protects neurons from glutamatergic damage during prolonged seizures.

Pain Management

The dissociative anesthetic effects of ketamine have also been applied within the realm of postoperative pain management. Low doses of ketamine have been found to significantly reduce morphine consumption as well as reports of nausea following abdominal surgery.
Oral Ketamine
Ketamine can be started using the oral route or patients may be changed from a subcutaneous infusion when pain is controlled.
Starting dose: 5-10mg four times daily.
Increase dose in 5-10mg increments.
Usual dose range: 10mg-60mg four times daily.
Subcutaneous ketamine infusion
Starting dose: 50-150mg/24 hours.
Review daily; increase dose in 50-100mg increments.
Usual dose range: 50mg- 600mg/24 hours
Converting from a 24 hour SC ketamine infusion to oral ketamine
Oral ketamine is more potent than SC ketamine (due to liver metabolism). Many patients require a dose reduction of 25-50% when changing to oral ketamine.
Titrate dose in 5-10mg increments.
Some specialists stop the SC infusion when the first dose of oral ketamine is given. Others gradually reduce the infusion dose as the oral dose is increased.
Side Effects
Short Term
Up to 40% of patients may experience side effects with continuous subcutaneous infusion (side effects are less common upon oral administration). These include:

Delirium
Dizziness
Diplopia
Blurred Vision
Nystagmus
Altered Hearing
Hypertension
Tachycardia
Hypersalivation
Nausea and Vomiting
Erythema
Pain at Injection Site
Psychomimetic Phenomenon
Euphoria
Aphasia
Blunted Affect
Psychomotor Retardation
Vivid Dreams
Nightmares
Impaired Attention, Memory and Judgement
Illusions
Hallucinations
Altered Body Image
Tonic-clonic movements are also reported at higher anesthetic doses in greater than 10% of patients.

Long Term
Because ketamine is typically administered as a few repeated doses in a clinical setting, long-term effects are primarily reported and investigated in recreational ketamine users.

Neurological Effects
Main article:
Olney’s lesions
Chronic use of ketamine may lead to cognitive impairments including memory problems. In 1989, psychiatry professor John Olneyreported that ketamine caused irreversible changes in two small areas of the rat brain, which however has significant differences in metabolism from the human brain and therefore may not occur in humans.
The first large-scale, longitudinal study of ketamine users found that heavy ketamine users had impaired memory by several measures, including verbal, short-term memory and visual memory. However, occasional (1-2 times per month) ketamine users and former ketamine users were not found to differ from controls in memory, attention and psychological well-being tests. This suggests that occasional use of ketamine does not lead to prolonged harm and that any damage that might occur may be reversible when ketamine use is stopped; however, depression worsened even in the abstinent user group over the period of the study (one year), along with dissociative symptoms still existing among infrequent users.
Short-term exposure of cultures of GABAergic neurons to ketamine at high concentrations led to a significant loss of differentiated cells in one study, and non-cell-death-inducing concentrations of ketamine (10 μg/mL) may still initiate long-term alterations of dendritic arbor in differentiated neurons. The same study also demonstrated that chronic (>24 h) administration of ketamine at concentrations as low as 0.01 μg/mL can interfere with the maintenance of dendritic arbor architecture. These results raise the possibility that chronic exposure to low, subanesthetic concentrations of ketamine, while not affecting cell survival, could still impair neuronal morphology and thus might lead to dysfunctions of neural networks.
There is a long list of medicines that could counteract these potential toxic effects, including clonidine,anticholinergics, benzodiazepines, barbiturates and risperidone.

Urinary Tract Effects
According to a recent systematic review, 110 documented reports of irritative urinary tract symptoms from ketamine dependence exist. Urinary tract symptoms have been collectively referred as ketamine-induced ulcerative cystitis or ketamine-induced vesicopathy, and they include urge incontinence, decreased bladder compliance, decreased bladder volume, detrusor overactivity, and painful haematuria (blood in urine). Bilateral hydronephrosis and renal papillary necrosis have also been reported in some cases.The pathogenesis of papillary necrosis has been investigated in mice, and it has been suggested that mononuclear inflammatoryinfiltration in the renal papilla resulting from ketamine dependence is a possible mechanism.
The time of onset of lower urinary tract symptoms varies depending, in part, on the severity and chronicity of ketamine use; however, it is unclear whether the severity and chronicity of ketamine use corresponds linearly to the presentation of these symptoms. All reported cases where the user consumed greater than 5 grams per day reported symptoms of the lower urinary tract. Urinary tract symptoms appear to be most common in daily ketamine abusers who have abused the drug for an extended period of time. These symptoms have presented in only one case of medical use of ketamine. However, following dose reduction, the symptoms remitted.
Management of these symptoms primarily involves ketamine cessation, for which compliance is low. Other treatments have been used, including antibiotics, NSAIDS, steroids, anticholinergics, and cystodistension. Both hyaluronic acid instillation and combinedpentosan polysulphate and ketamine cessation have been shown to provide relief in some patients, but in the latter case, it is unclear whether relief resulted from ketamine cessation, administration of pentosan polysulphate, or both. Further follow-up is required to fully assess the efficacy of these treatments.

Case reports of Hepato-Toxicity in Chronic Pain Management
In case reports of three patients treated with S(+)ketamine for relief of chronic pain, liver enzyme abnormalities occurred following repeat treatment with ketamine infusions, with the liver enzyme values returning below the upper reference limit of normal range on cessation of the drug. The result suggests that liver enzymes have to be monitored during such treatment.

Drug Interactions
Ketamine may increase the effects of other sedatives, including but not limited to: benzodiazepines, barbiturates, opiates/opioids,anesthetics, and alcoholic beverages.

Mechanism of Action
Central nervous system:
Ketamine is a noncompetitive NMDA receptor (NMDAR) antagonist. More specifically, ketamine binds to the allosteric site of the NMDA receptor, effectively inhibiting its channel. The S(+) and R(-) stereoisomers bind with different affinities: Ki = 3200 and 1100 nM, respectively. NMDAR antagonism effects analgesia by preventing central sensitization in dorsal horn neurons; in other words, ketamine’s actions interfere with pain transmission in the spinal cord. Ketamine also inhibits nitric oxide synthase, inhibiting production of nitric oxide, a neurotransmitter involved in pain perception, and hence further contributing to analgesia. Ketamine also interacts with sigma and opioid receptors, but with lower affinity and without significantly contributing to analgesia.
Ketamine also interacts with a host of other receptors to effect analgesia. It blocks voltage-sensitive calcium channels and depressessodium channels, attenuating hyperalgesia; it alters cholinergic neurotransmission, which is implicated in pain mechanisms; and it acts as a noradrenergic and serotonergic uptake inhibitor, which are involved in descending antinociceptive pathways.
