产品描述:
Vigabatrin is an irreversible GABA transaminase (GABA-T) inhibitor.{55297} It inhibits rat brain GABA-T when used at a concentration of 0.1 mM. Vigabatrin is selective for rat brain GABA-T over P. fluorescens GABA-T at 10 mM and is 100-fold selective over rat brain glutamic acid decarboxylase (GAD). Vigabatrin (1,500 mg/kg) decreases brain GABA-T activity without affecting GAD activity in mice.{55298} It reduces the incidence of myoclonus in a mouse model of audiogenic seizures.{55299} Vigabatrin also increases the electroconvulsive threshold in mouse model of maximal electroshock-induced seizures and reduces the number of clonic convulsions induced by pentylenetetrazol (PTZ; Item No. 18682) in mice.{55300} Formulations containing vigabatrin have been used in the treatment of seizures and infantile spasms.
