Vigabatrin is an irreversible GABA transaminase inhibitor used as an adjunct therapy to treat refractory complex partial seizures in patients ≥2 years unresponsive to alternatives. May also be used as monotherapy to treat infantile spasms in infants 1 month to 2 years.
Vigabatrin is an irreversible GABA transaminase inhibitor used as an adjunct therapy to treat refractory complex partial seizures in patients ≥2 years unresponsive to alternatives. May also be used as monotherapy to treat infantile spasms in infants 1 month to 2 years.
Gamma-aminobutyric acid (GABA) is the major inhibitory transmitter throughout the central nervous system, and the potentiation of GABAergic neurotransmission is therefore a crucial mechanism through which antiepileptic agents may combat the pathologic excitatory neurotransmission seen in epilepsy. Vigabatrin increases concentrations of GABA in the central nervous system by irreversibly inhibiting the enzymes responsible for its metabolism to succinic semialdehyde: gamma-aminobutyric acid transaminase (GABA-T).
Vigabatrin is indicated as adjunctive therapy in the treatment of refractory complex partial seizures in patients 2 years of age and older who have had inadequate responses to multiple previous treatments (i.e. not to be used for first-line therapy). It is also indicated as monotherapy in the treatment of infantile spasms in patients between 1 month and 2 years of age for whom the potential benefits outweigh the risk of vision loss.
