Background:
Vigabatrin-13C-d2is intended for use as an internal standard for the quantification of vigabatrin by GC- or LC-MS. Vigabatrin is an irreversible GABA transaminase (GABA-T) inhibitor.1It inhibits rat brain GABA-T when used at a concentration of 0.1 mM. Vigabatrin is selective for rat brain GABA-T overP. fluorescensGABA-T at 10 mM and is 100-fold selective over glutamic acid decarboxylase (GAD). Vigabatrin (1,500 mg/kg) decreases brain GABA-T activity without affecting GAD activity in mice.2It reduces the incidence of myoclonus in a mouse model of audiogenic seizures.3Vigabatrin also increases the electroconvulsive threshold in mouse model of maximal electroshock-induced seizures and reduces the number of clonic convulsions induced by pentylenetetrazol in mice.4Formulations containing vigabatrin have been used in the treatment of seizures and infantile spasms.
