Combination of ramipril and hydrochlorothiazide in the treatment of mild to moderate hypertension--Part 2: An open long-term study of efficacy and safety.

In an open, multicenter extension of a short-term study, 159 patients with mild to moderate hypertension were treated with either ramipril monotherapy or a combination of ramipril and hydrochlorothiazide for up to 1 year. Patients started with either 5 mg ramipril once daily (responders in the short-term study) or a combination of ramipril 5 mg plus hydrochlorothiazide 25 mg once daily. The dose could be adjusted and nonresponders to ramipril monotherapy could have hydrochlorothiazide added.

Combination of ramipril and hydrochlorothiazide in the treatment of mild to moderate hypertension: Part 1--A double-blind, comparative, multicenter study in nonresponders to ramipril monotherapy.

In a parallel-group multicenter study, the efficacy and safety of combination therapy with ramipril 5 mg plus hydrochlorothiazide 25 mg were compared double-blind with those of 5 mg and 10 mg ramipril monotherapy in patients with mild to moderate hypertension who had not responded adequately to ramipril 5 mg alone. Patients were initially treated single-blind for 1 week with ramipril 2.5 mg and 3 weeks with ramipril 5 mg.

Efficacy and safety of ramipril in combination with hydrochlorothiazide: results of a long-term study.

Hypertensive patients from a double-blind study comparing 5 mg of ramipril, 10 mg of ramipril, and 5 mg of ramipril + 25 mg of hydrochlorothiazide (HCTZ) were enrolled in an open 1-year extension study with ramipril and concomitant HCTZ. The starting dose of ramipril was 5 mg/day. Patients were given 25 mg of HCTZ in addition only if their diastolic blood pressure (DBP) was higher than 90 mm Hg.
