Comparison of the efficacy and tolerability of telmisartan and enalapril in patients of mild to moderate essential hypertension.

Background: Theoretically, angiotensin II receptor blockers (ARBs) have certain advantages over angiotensin-converting enzyme inhibitors, but the contribution of these advantages to the clinical effect of ARBs is not known.

Objective: To compare the efficacy and tolerability of telmisartan with enalapril in patients of essential hypertension.

Materials And Methods: Patients of mild to moderate hypertension were randomized to receive either 40 mg of telmisartan or enalapril 10 mg once a day orally for 12 weeks.
