Abstract：
:Calcium channel blockers appear to reduce the cardiac toxicity of cocaine and some stimulant-induced behaviors. The present experiment was designed to test whether the internal state induced by cocaine is altered by the calcium antagonist nimodipine. Substitution tests with the calcium agonist BAY K 8644 were also conducted in rats (N = 8) trained to discriminate cocaine (10 mg/kg) from saline in a two-lever, water-reinforced drug discrimination paradigm. Cocaine (0.625-10 mg/kg) produced a dose-related increase in drug-lever responding while BAY K 8644 (0.25-2 mg/kg) and nimodipine (0.2-0.8 mg/kg) engendered primarily saline responding. In combination with cocaine (2.5-10 mg/kg), nimodipine shifted the cocaine dose-response curve to the right at doses of 0.2 and 0.4 mg/kg; this attenuation did not increase with higher doses of nimodipine (0.8 and 1.6 mg/kg). The present results suggest that nimodipine may partially block the discriminative stimulus properties of cocaine, however, this reduction is neither robust nor dose-related. Thus, nimodipine might be expected to only marginally alter the subjective cocaine state in humans.
