Why it is prescribed (Indications):

 This medication is a barbiturate, prescribed for seizures, and treating sleep disorders.  It works by slowing the activity in the brain.

How does it work?
Phenobarbital (previously known as phenobarbitone in the UK) belongs to a group of medicines called barbiturates. It is used to treat epilepsy and works by stabilising electrical activity in the brain.

The brain and nerves are made up of many nerve cells that communicate with each other through electrical signals. These signals must be carefully regulated for the brain and nerves to function properly. When abnormally rapid and repetitive electrical signals are released in the brain, the brain becomes over-stimulated and normal function is disturbed. This can result in fits or seizures.

Phenobarbital prevents epileptic fits by preventing the excessive electrical activity in the brain. It is thought to achieve this by affecting certain neurotransmitters in the brain.

Neurotransmitters are chemicals that are stored in nerve cells and are involved in transmitting messages between the nerve cells. GABA is a neurotransmitter that acts as a natural 'nerve-calming' agent. It helps keep the nerve activity in the brain in balance. Glutamate is a neurotransmitter that acts as a natural 'nerve-exciting' agent. It is released when electrical signals build up in nerve cells and subsequently excites more nerve cells. It is thought to play a key role in causing epileptic seizures.

Phenobarbital increases the activity of GABA and decreases the activity of glutamate in the brain. These actions help stabilise the electrical activity in the brain and prevent epileptic fits.

Phenobarbital is available as tablets, elixir and injection. The injection is used to control repeated fitting, when consciousness is not regained between seizures. This condition is called status epilepticus.
