title: [The influence of calcium channel blockers on the effects of haloperidol and phenamine in mice and rats].
abstract: Effects of verapamil (5 and 25 mg/kg), nifedipine (5 and 10 mg/kg), diltiazem (5, 10 and 20 mg/kg), cinnarizine (25 and 50 mg/kg), and fendilin (20 mg/kg) on the haloperidol (3 mg/kg)-induced catalepsy have been studied in rats. In higher doses these drugs attenuate and in lower doses potentiate the action of haloperidol. The bilateral intrastriatal injection of verapamil (5 mcg), diltiazem (5 mcg), and nimodipine (0.4 mcg) also alleviates the haloperidol catalepsy. Intraperitoneal administration of calcium channel blockers potentiated the amphetamine group toxicity in mice. No mediation of the effects of calcium channel blockers via dopaminergic processes is assumed.
