Vigabatrin

Vigabatrin is an anticonvulsant used for infantile spasms and certain complex partial seizures . Vigabatrin brand names are Sabril , Vigadrone , Vigpoder , Vigafyde , and some generic products are available. Vigabatrin is thought to work by stabilizing and calming brain electrical activity by increasing the amount of an inhibitory neurotransmitter (chemical messenger) called GABA (gamma aminobutyric acid). Vigabatrin mechanism of action is blocking an enzyme called GABA-T (GABA-transaminase), which usually breaks down; this results in an increase in  GABA levels in the brain, which is thought to improve infantile spasms and some complex seizures. Vigabatrin FDA approval was first granted in 2009 under the brand name Sabril.
