title: Effect of prostaglandin synthetase inhibitors on experimentally induced convulsions in rats.
abstract: To investigate the relationship of prostaglandins (PGs) to seizure induction, the effects of six PG synthetase inhibitors on convulsions induced by flurothyl, picrotoxin, pentetrazol (PTZ), electroshock or bicuculline were evaluated. Ibuprofen, sulindac, mefenamic acid, and low dose meclofenamic acid increased the latency-to-onset in the flurothyl and/or PTZ models; the electroshock, picrotoxin and bicuculline models were not significantly affected by any of the pretreatment agents. These results suggest that PGs are involved in the mechanism(s) underlying fluorthyl- and PTZ-induced convulsions, but not picrotoxin-, electroshock-, or bicuculline-induced convulsions.
