Abstract

Abstract Possible involvement of prostaglandins (PG) in the antimyoclonic action of clonazepam was examined in the p,p′-DDT-animal model of myoclonus. PG synthesis inhibitors and the PG antagonist polyphloretin phosphate (PPP) counteracted the antimyoclonic action of clonazepam in mice. PGE 2 reduced DDT-induced myoclonus; this effect was blocked by PPP. Another antimyoclonic drug combination, L-5-hydroxytryptophan plus chlorimipramine, was not blocked by PPP or indomethacin. The antimyoclonic action of clonazepam may be mediated by enhancement of PG synthesis.
