Lacidipine: a review of its use in the management of hypertension.

Abstract

UNLABELLED:

Lacidipine (Caldine, Lacimen, Lacipil, Midotens, Motens) is a once-daily, orally-administered, lipophilic dihydropyridine calcium antagonist with an intrinsically slow onset of activity, resulting in a lack of reflex tachycardia. It has a long duration of action and a high degree of vascular selectivity. In addition to calcium channel-modulated vasodilation, lacidipine displays antioxidant activity greater than that of other dihydropyridine calcium antagonists. In randomised, well-controlled trials, lacidipine 2-6 mg orally once daily had antihypertensive efficacy similar to that of other long-acting dihydropyridine calcium antagonists, thiazide diuretics, atenolol (a beta-blocker) and enalapril (an ACE inhibitor). Lacidipine was effective in elderly patients (including those with isolated systolic hypertension), African Nigerian patients and patients with concurrent type 2 diabetes mellitus. During long-term treatment for 4 or 5 years in patients with isolated systolic hypertension or essential hypertension, the incidence of cardiovascular events and mortality with lacidipine was similar to that with chlorthalidone or atenolol. The European Lacidipine Study on Atherosclerosis (ELSA), in which 2334 patients with hypertension were randomised to 4 years of therapy with lacidipine 4-6 mg/day or the beta-blocker atenolol 50-100 mg/day, demonstrated significantly lower atherosclerotic progression and plaque formation with lacidipine compared with atenolol in patients completing the full 4 years of the study. Between-group differences in favour of lacidipine for the primary efficacy variable (mean change in carotid artery intima-media thickness) did not reach statistical significance in the intent-to-treat population. The tolerability profile of lacidipine (headache, flushing, pedal oedema, dizziness and palpitations) is similar to that of other dihydropyridine calcium antagonists, but with a lower incidence of peripheral oedema. Data from the ELSA study suggest that the incidence of serious adverse events during long-term lacidipine therapy is similar to that with atenolol.

CONCLUSION:

Lacidipine is an effective, well tolerated, once-daily, oral antihypertensive agent that can be used in a wide variety of patients. As with other members of its class, lacidipine has shown potentially beneficial antiatherosclerotic effects, although definitive data with respect to possible superiority over other drug classes are still required. Therefore, lacidipine is an attractive therapy for the long-term management of essential hypertension.
