The therapeutic profile of olmesartan medoxomil, which is a recently developed angiotensin II (A II) receptor blocker, has been compared with four commonly used antihypertensive therapeutic drugs (atenolol, captopril, felodipine and losartan) in five separate multicentre, randomised, double-blind, parallel-group, phase III trials. The trials were designed to compare the efficacy of individually optimised dosages of olmesartan medoxomil and the comparator agent. The primary efficacy variable in all trials was the mean change from baseline to week 12 in trough mean sitting diastolic blood pressure (DBP). Olmesartan medoxomil (10–20 mg once daily (o.d.)) showed similar efficacy to atenolol (50–100 mg o.d.), both in patients with mild-to-moderate hypertension and, when given together with hydrochlorothiazide (HCTZ) 25 mg o.d., in patients with moderate-to-severe hypertension. Olmesartan medoxomil (20–40 mg o.d.) was also similar in efficacy to felodipine (5–10 mg o.d.) in reducing BP in patients with mild-to-moderate hypertension. Compared with captopril (12.5–50 mg twice daily (b.i.d.)) and losartan (50–100 mg o.d.), in patients with mild-to-moderate hypertension, olmesartan medoxomil (5–20 mg o.d. and 10–20 mg o.d., respectively) was significantly superior in terms of lowering DBP from baseline to week 12. In terms of the secondary efficacy variable, which was mean change from baseline to week 12 in trough mean sitting systolic BP, olmesartan showed significant superiority to atenolol, captopril and losartan in patients with mild-to-moderate hypertension. In the longer term, compared with losartan, a lower percentage of olmesartan-treated patients required concomitant HCTZ after 12 weeks of therapy. Olmesartan was well tolerated in all studies.
