Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Hypertension Type 2 Diabetes Albuminuria Drug: ramipril Drug: ramipril-telmisartan Phase 3

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
