title: Antihypertensive efficacy of candesartan in comparison to losartan: the CLAIM study.
abstract: An 8-week, multicenter, double-blind, randomized, parallel-group, forced-titration study was conducted to evaluate the antihypertensive efficacy of candesartan vs. losartan in 654 hypertensive patients with a diastolic blood pressure between 95 and 114 mm Hg from 72 sites throughout the U.S. Eligible patients were randomized to candesartan cilexetil 16 mg once daily, or losartan 50 mg once daily. Two weeks following randomization, patients doubled the respective doses of their angiotensin receptor blockers for an additional 6 weeks. At week 8, candesartan cilexetil lowered trough systolic/diastolic blood pressure by a significantly greater amount than did losartan (13.3/10.9 mm Hg with candesartan cilexetil vs. 9.8/8.7 mm Hg with losartan; p less than 0.001). At the same period, candesartan cilexetil also lowered peak blood pressure by a significantly greater amount than did losartan (15.2 to 11.6 mm Hg with candesartan cilexetil vs. 12.6 to 10.1 mm Hg with losartan; p less than 0.05). There were statistically significantly (p less than 0.05) higher proportions of responders and controlled patients in the candesartan cilexetil group (62.4% and 56.0%, respectively) than in the losartan group (54.0% and 46.9%, respectively). Both treatment regimens were well tolerated; 1.8% in the candesartan cilexetil group and 1.6% in the losartan group withdrew because of adverse events. In conclusion, this forced-titration study confirms that candesartan cilexetil is more effective than losartan in lowering blood pressure when both are administered once daily at maximum doses. Both drugs were well tolerated. (c)2001 by Le Jacq.
