Abstract
Background: To study the interaction of calcium channel blocker (Nifedipine) with Antipsychotic drug (Haloperidol) on Conditioned avoidance Response and catalepsy in Rats. Methods: Every group consisted of 10 healthy albino rats of either sex. Different groups received Nifedipine (5, 10 & 20 mg/kg, i.p.), Haloperidol (ED50 -0.2mg/kg for CAR & 0.4mg/kg for catalepsy) alone and combined doses of both drugs. The Antipsychotic effect of drugs was measured by Conditioned avoidance response (CAR) using Cook’s Pole climbing apparatus and Adverse drug effect (Extra pyramidal syndrome) was measured by Catalepsy. Results: 5 mg/kg i.p. of Nifedipine inhibited CAR in 50 % of Rats (compared to control, p
