Vigabatrin Hydrochloride is primarily used in the treatment of epilepsy, specifically for managing refractory complex partial seizures in adults and as a therapy for infantile spasms in children. It works by inhibiting the breakdown of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the brain, thereby increasing GABA levels and reducing seizure activity. This medication is often prescribed when other antiepileptic drugs have failed to control seizures effectively. Due to its potential to cause vision loss, its use is closely monitored, and regular ophthalmologic evaluations are required during treatment. It is administered orally and is available in tablet or powder form for solution.
