Abstract:
In this double blind cross over study against placebo the in vivo effects of diltiazem, nifedipine and verapamil on platelet aggregation and Thromboxane A2 (TxA2) formation were evaluated in eighteen healthy adults. No significant inhibition of platelet aggregation or TxA2 formation was found either after acute or short term (8 days) administration of the three calcium channel blockers at the usual therapeutical dosages. Our study indicate that diltiazem, nifedipine and verapamil are unable to significantly affect platelet aggregation and TxA2 formation in healthy subjects.
