Vigabatrin (VGB) is a structural analogue of gamma-aminobutyric acid (GABA) that irreversibly inhibits GABA-transaminase (GABA-T), increasing brain levels of GABA. VGB is under assessment for treatment of infantile spasms (IS) and refractory complex partial seizures (CPS). Response can be rapid...

Infantile spasms (IS) are a unique and severe form of epilepsy associated with poor neurologic and developmental outcomes. The refractory spasms and abnormal electroencephalogram (EEG) patterns associated with the condition are believed to have a progressively detrimental impact. Therefore, rapid...
