Objective: To study the effect of candesartan cilexetil (CC) in the management of blood pressure (BP) in diabetic and non-diabetic hypertensive patients.

Methods: A selection of five randomized double-blind clinical trials in which patients were treated for hypertension with CC was analyzed. All of these were similar in design: i) a 4-week placebo run-in period, ii) a 4- to 6-week period (V1) with CC 8 mg once daily (od), after which the dosage was doubled if BP was not normalized (BP >140/90 or BP >130/80 mmHg in diabetes), and iii) a 4- to 6-week period (V2) with CC 8 or 16 mg od. Efficacy was measured at V1 and V2.

Results: 702 patients were screened. The population consisted of 397 males (56.6%) with a mean age of 60 ± 11 years, with 153 diabetic (21.8%) and 549 non-diabetic (78.2%) patients. At baseline, mean BP values were 160/94/65 mmHg for SPB, DBP, and pulse pressure (PP) respectively, with differences between diabetic and non-diabetic patients. SBP, DBP, and PP values showed a significant reduction at V1 (p < 0.001) and V2 (p < 0.001) compared with baseline for all hypertensive patients. Mean changes at V2 in SBP and PP values were higher in diabetic than non-diabetic patients (p < 0.001), and to a lesser degree on DBP values (p = 0.034).

Conclusions: CC was effective in lowering BP in diabetic and non-diabetic hypertensive patients. CC is a promising therapy to manage hypertensive diabetic patients, as demonstrated by the significant BP reduction.

Short abstract: The effect of candesartan cilexetil (CC) on controlling blood pressure (BP) in hypertensive diabetic and non-diabetic patients was analyzed. Five randomized double-blind trials were pooled treating hypertension by CC (n = 702), including 153 diabetic (21.8%) and 549 non-diabetic (78.2%) patients. After treatment with CC (8–16 mg), significant reductions in SBP, DBP, and pulse pressure (PP) values were observed after 4–6 weeks (p < 0.001) and after 8–12 weeks (p < 0.001) compared with baseline for all hypertensive patients. Mean BP reductions after 8–12 weeks were higher in diabetic patients than non-diabetic (p < 0.001). CC is a promising therapy to treat hypertensive patients, both diabetic and non- diabetic.
