Effective dose range of candesartan cilexetil for systemic hypertension. Candesartan Cilexetil Study Investigators.

The results of this randomized, double-blind, placebo-controlled, forced-dose titration study in a diverse population of hypertensive patients in the US indicate that candesartan cilexetil has clinically meaningful dose-related blood pressure-lowering effects and that maximum blood pressure reduction is achieved with doses of 16 and 32 mg given once daily. This study confirms that candesartan cilexetil is a highly effective antihypertensive agent with an excellent tolerability and safety profile, without dose-related adverse effects.

Comparative effects of candesartan cilexetil and losartan in patients with systemic hypertension. Candesartan Versus Losartan Efficacy Comparison (CANDLE) Study Group.

The antihypertensive efficacy and tolerability of the novel angiotensin-II (A-II) receptor blocker candesartan cilexetil and the prototype A-II receptor blocker, losartan, were compared in an 8-week, multicenter, double-blind, randomized, parallel-group, titration-to-effect study of 332 adults (42% women, 12% black) with systemic hypertension (sitting diastolic blood pressure [DBP] 95-114 mmHg, inclusive). In patients with a mean trough (24 +/- 3 hours after dose) sitting DBP of 90 mmHg or higher after 4 weeks of once daily administration of candesartan 16 mg or losartan 50 mg, dose was titrated up to candesartan 32 mg or losartan 100 mg once daily. The candesartan regimen was significantly more effective than the losartan regimen in reducing trough sitting DBP at week 8 (11.0 mmHg versus 8.9 mmHg). Candesartan also produced numerically greater reductions in secondary blood pressure parameters, including sitting systolic blood pressure (SBP), trough standing DBP and SBP, and peak (6 +/- 2.5 hours after dose) sitting and standing DBP and SBP. Responder rates (sitting DBP < 90 mmHg or reduction in blood pressure of > or = 10 mmHg) and control rates (sitting DBP <90 mmHg) were higher with candesartan (64% versus 54% and 54% versus 43%, respectively). A total of 1.9% of the patients taking candesartan and 6.5% of those taking losartan discontinued prematurely because of adverse events or lack of efficacy.
