Although they have generally been effective and well tolerated, recent concerns about their safety await the results of well designed, long term clinical trials currently underway. Calcium channel antagonists block the slow calcium channels in the myocardium and vascular smooth muscle, leading to coronary and peripheral vasodilation.Table 150-4 -- Selected Characteristics of Some Calcium Channel Blockers.

Currently approved calcium-channel blockers (CCBs) bind to L-type calcium channels located on the vascular smooth muscle, cardiac myocytes, and cardiac nodal tissue (sinoatrial and atrioventricular nodes). Doses of calcium channel blockers used in treating hypertension are similar to those used in treating angina. Some epidemiologic studies reported an increased risk of myocardial infarction or mortality in patients receiving short-act-ing nifedipine for hypertension.
