Vigabatrin is used to treat epilepsy. It works by stabilising electrical activity in the brain.
Vigabatrin works by affecting the activity of a neurotransmitter called GABA. Neurotransmitters are natural body chemicals that are stored in nerve cells. They 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 electrical nerve activity in the brain in balance. Vigabatrin prevents the breakdown of GABA in the brain. This enables GABA to calm the nerve activity in the brain for a longer period of time, which helps to prevent seizures.
