Abstract
The protective effect of two benzodiazepine compounds, diazepam and clonazepam was tested against isoniazid (INH)- induced convulsions in rats pretreated with the gamma-amino-butyric acid (GABA) transaminase inhibitor viz., aminooxyacetic acid (AOAA), and the result was compared with that produced by the two drugs independently. Rats treated 6 h and not 30 min previously with AOAA showed a dose-dependent inhibition of INH-induced convulsions. In these animals both diazepam and clonazepam showed a greater protective effect than that produced by them alone. It is suggested from these findings that, even if their anticonvulsant mechanisms are distinct, with or without the involvement of GABA, AOAA and the benzodiazepine compounds seem to act synergistically against INH-induced convulsions.
