Amlodipine (5-10 mg, once daily) and enalapril (10-40 mg, once daily) were compared in terms of quality of life, efficacy, and tolerability, in a multicenter, double-blind trial lasting for 50 weeks in 461 mild or moderate hypertensive patients. Both drugs were similarly effective in lowering blood pressure while maintaining quality of life. Apart from class-typical effects, such as edema for calcium antagonists, and cough for angiotensin-converting enzyme inhibitors, both drugs were equally well tolerated, with few adverse effects of clinical significance. Only a few patients [eight amlodipine (4%); nine enalapril (4%)] were withdrawn from the trial due to drug-related adverse events, demonstrating that tolerability was good. Neutral to slightly beneficial effects were found in blood lipid concentrations after treatment with amlodipine. Both drugs reduced the calculated risk of coronary heart disease over the next 10 years. It was concluded that amlodipine compared favorably with enalapril as an effective and well-tolerated antihypertensive drug.
