Summary Catalepsy was observed in the rat following intrastriatal injections of the dopamine antagonists sulpiride or fluphenazine and after subcutaneous administration of fluphenazine. The neuroleptic-induced catalepsy was reversed by the classical anti-parkinsonian agent L-DOPA and by agents that function through dopamine systems such as d- and methamphetamine and the direct D2 receptor agonist quinpirole. The D1 agonist SKF 38393, and the D1/D2 agonist apomorphine, were ineffective in this model. These results support limited use of the rat catalepsy model for the screening of potential anti-parkinsonian compounds and indicate that this procedure can provide valuable information concerning striatal dopamine function.
