Abstract
A double-blind, double-dummy, randomised, multicentre study to compare the efficacy and tolerability of lercanidipine with losartan. Patients with mild to moderate hypertension (supine diastolic blood pressure (DBP) 95–115 mm Hg) were enrolled and underwent a placebo run-in period of 14–30 days before random allocation to lercanidipine tablets 10 mg once-daily (n = 234) or losartan tablets 50 mg once-daily (n = 231) during the assessment period (approximately 16 weeks). Titration to lercanidipine 20 mg once-daily (two 10 mg tablets) or losartan 100 mg once-daily (two 50 mg tablets) was allowed after 8 weeks, if necessary. At the end of the study, 71% of patients who received lercanidipine tablets had achieved normalised DBP (ie, ⩽90 mm Hg) and 81% had responded to treatment (ie, DBP ⩽90 mm Hg or a decrease in DBP ⩾10 mm Hg). The corresponding numbers in the losartan tablets group were 65% and 78%, respectively. In those patients who required dose titration, there was evidence of a greater response with lercanidipine tablets than with losartan tablets. Both treatments were well tolerated with a low incidence of adverse drug reactions and a low withdrawal rate. In conclusion, the antihypertensive effects of lercanidipine tablets were comparable with those of losartan tablets; both treatments gave a high response rate for an antihypertensive monotherapy and were very well tolerated.
