title: Lercanidipine : a review of its efficacy in the management of hypertension.
abstract: Lercanidipine (Zanidip) is a vasoselective dihydropyridine calcium channel antagonist that causes systemic vasodilation by blocking the influx of calcium ions through L-type calcium channels in cell membranes. It is a highly lipophilic drug that exhibits a slower onset and longer duration of action than other calcium channel antagonists. Furthermore, lercanidipine may have antiatherogenic activity unrelated to its antihypertensive effect. In two large, nonblind, noncomparative studies involving approximately 16 000 patients with mild-to-moderate hypertension, systolic blood pressure (BP) [SBP] and diastolic BP (DBP) were significantly reduced after 12 weeks' treatment with lercanidipine 10-20 mg/day. Furthermore, in the largest study, 64% of patients were responders (DBP <90 mm Hg) after 12 weeks of treatment and an additional 32% had their BP normalised (BP <140/90 mm Hg). In comparative trials, lercanidipine 10-20 mg/day was as effective as nifedipine slow release (SR) 20-40 mg twice daily, amlodipine 10 mg/day, felodipine 10-20 mg/day, nifedipine gastrointestinal therapeutic system (GITS) 30-60 mg once daily or verapamil SR 240 mg/day at reducing SBP and DBP in patients with mild-to-moderate hypertension after 2-16 weeks of therapy. In addition, 4 weeks of lercanidipine therapy (10 mg/day) was as effective as captopril 25mg twice daily, atenolol 50 mg/day or hydrochlorothiazide 12.5 mg/day. Lercanidipine 5-30 mg/day effectively decreased BP in elderly patients (aged >60 years) with mild-to-moderate hypertension or isolated systolic hypertension to the same extent as amlodipine 5-10 mg/day, nifedipine GITS 30-60 mg/day or lacidipine 2-4 mg/day after 24-26 weeks of therapy. In addition, a limited number of studies suggest that lercanidipine may have antihypertensive efficacy in patients with severe or resistant hypertension, in hypertensive patients with type 2 diabetes mellitus and in postmenopausal women with mild-to-moderate essential hypertension. Lercanidipine is well tolerated, with most treatment-emergent events related to vasodilation. Common adverse events included headache, flushing and peripheral oedema. Importantly, the incidence of vasodilatory oedema was significantly lower in patients receiving lercanidipine than in those receiving some other calcium channel antagonists.
  
  
  CONCLUSIONS
  Once-daily lercanidipine is an effective and well tolerated antihypertensive agent in patients with mild-to-moderate hypertension.
