Interactions of cocaine with nimodipine: a brief report

Am J Addict. 1999 Winter;8(1):77-81. doi: 10.1080/105504999306117.


This double blind, placebo controlled study of acute calcium channel antagonist use during cocaine administration in five patients found that 60 mg of nimodipine treatment attenuated the systolic, but not diastolic, blood pressure effects of cocaine. In three subjects, a 90 mg dose of nimodipine showed a greater attenuation than that of 60 mg. Subjective effects of cocaine were not altered by either dose of nimodipine.
