Role of a third generation calcium antagonist in the management of hypertension.
Calcium antagonists are uniquely suitable for managing hypertension by virtue of their efficacy, metabolic neutrality and their ability to countervail counterregulatory adaptive changes, thereby enhancing blood pressure lowering. Recent evidence has accrued underscoring the concept that calcium antagonists are heterogeneous and consist of chemically dissimilar agents. The difference in formulations and pharmacokinetics affect clinical events including the effect on blood pressure, heart rate and the degree with which sympathetic activity is activated. Lacidipine is a new calcium antagonist that is the prototype of the lipophilic dihydropyridines. Of great importance, lacidipine has a slow onset of vasodilator/antihypertensive effect and does not promote an excessive sympathetic drive. These attributes commend its selection as an antihypertensive agent.
