Abstract
Both nifedipine and verapamil, the calcium channel blockers were tested to determine their anti-leukotriene properties in pig uterine strips. These drugs in concentrations ranging from 1.10(-7)M to 1.10(-5)M significantly attenuated the constrictor effects of cysteinyl leukotrienes in pig uterus. Thus, leukotrienes C4, D4 and E4 are dependent upon Ca2+ for their myotropic activity, an action non-competitively inhibited by the calcium channel blockers nifedipine and verapamil.
