The effect of a dihydropyridine (DHP) calcium antagonist, PN 200-110, on cocaine reinforcing properties was investigated using conditioned place preference paradigm. PN 200-110 in nonsedative doses (0.62-1.25-2.5 mg/kg SC) was able to inhibit cocaine- (10 mg/kg IP) induced place preference with ED50 1.57 (0.88-2.58). The results suggest a possible use of DHPs in the treatment of cocaine-related disorders.

Abstract
The effect of a dihydropyridine (DHP) calcium antagonist, PN 200-110, on cocaine reinforcing properties was investigated using conditioned place preference paradigm. PN 200-110 in nonsedative doses (0.62-1.25-2.5 mg/kg SC) was able to inhibit cocaine- (10 mg/kg IP) induced place preference with ED50 1.57 (0.88-2.58). The results suggest a possible use of DHPs in the treatment of cocaine-related disorders.
