Condition(s) targeted: Hypertension; Type 2 Diabetes; Albuminuria

Intervention: ramipril (Drug); ramipril-telmisartan (Drug)

Phase: Phase 3

Status: Terminated

Sponsored by: Institut de Recherches Cliniques de Montreal

The purpose of this study is to determine if a dose of ramipril combined with a normal dose of telmisartan 80 mg will be more effective than ramipril 20 mg in reducing microalbuminuria in hypertensive patients with diabetes.

Clinical Details

Official title: Comparison of a Higher Dose of Ramipril to the Addition of Telmisartan 80 mg+Ramipril 10 mg in Patients With Hypertension and Diabetes

Detailed description: The purpose of this study is to determine the effects of ramipril 10 mg and telmisartan 80 mg versus ramipril 20 mg in patients with diabetes type II, hypertension and microalbuminuria (Urinary-albuminuria creatinine ratio of 2. 0 to 25 mg/mmol) on 1. Microalbuminuria 2. Blood pressure (systolic, diastolic and ABPM), Renin-angiotensin system, Catecholamines, Oxydative stress 3. Comparison at 4, 8 and 12 weeks with addition of hydrochlorothiazide 12. 5 mg if BP over 130/80 mmHg
