Abstract
Calcium channel blockers (CCBs) share a common mechanism of action. However, the manner in which they exert their pharmacological effects is different between subclasses. Dihydropyridine (DHP) CCBs tend to be more potent vasodilators than non-dihydropyridine (non-DHP) agents, whereas the latter have more marked negative inotropic effects. Both subclasses have a similar capacity to lower BP; however, non-DHPs appear to offer potential advantages in the management of patients with chronic kidney disease and diabetic nephropathy. Representatives of both classes are now available in fixed-dose combinations containing an ACE inhibitor, the benefits of which include effective 24-hour BP control, a reduced incidence of adverse effects, and improved adherence.
