The efficacy and tolerability of candesartan cilexetil in an elderly hypertensive population.
This study was performed to evaluate the antihypertensive efficacy and tolerability of candesartan cilexetil 8-16 mg once-daily in comparison with placebo in elderly hypertensive patients. Forty-one hospital and general practice centres in the Netherlands and in the United Kingdom enrolled 350 patients over 65 years of age with essential hypertension (WHO grades I or II). Patients with supine diastolic BP in the range 95-114 mm Hg after 4- to 8-week placebo run-in period (n = 193) were randomised to double-blind therapy with candesartan cilexetil or placebo. The initial dose of candesartan cilexetil 8 mg or placebo was doubled after 6 weeks if supine diastolic blood pressure (BP) exceeded 90 mm Hg. Mean (95% confidence interval) placebo-corrected reduction in supine diastolic BP after 12 weeks' treatment with candesartan cilexetil was 7.5 mm Hg (3.6-11.4; P < 0.001); the corresponding reduction in supine systolic BP was 13.6 mm Hg (6.9-20.2; P < 0.001). Placebo-corrected mean reduction in supine diastolic BP 2 and 4 h after the first dose of candesartan cilexetil were 2.2 mm Hg (-1.3 to +5.8; P = 0.219) and 4.0 mm Hg (-0.4 to +7.6; P = 0.027), respectively. Candesartan cilexetil had almost no influence on heart rate and did not affect the normal orthostatic changes in BP. Adverse events were equally common in the two treatment groups. Candesartan cilexetil 8-16 mg once-daily is an effective antihypertensive agent in elderly patients. The onset of action is smooth with no exaggerated response after the first dose and there is no postural hypotension. Candesartan cilexetil is very well tolerated in elderly hypertensives.
