Moexipril in the treatment of mild to moderate essential hypertension: comparison with sustained-release verapamil

To compare and contrast the antihypertensive efficacy of an angiotensin-converting enzyme (ACE) inhibitor to a calcium antagonist, 88 and 90 patients with essential hypertension were randomly assigned to receive moexipril and verapamil, respectively. At the end of the first 6 weeks of active therapy, sitting diastolic blood pressure decreased by 11 mmHg in patients receiving moexipril and by 9 mmHg in patients receiving verapamil. The 24-week treatment period was completed by 72 patients who received moexipril and 71 patients who received verapamil. Mean decreases in sitting diastolic blood pressure of 10 mmHg and 11 mmHg were observed in the respective intent-to-treat moexipril and verapamil groups. At doses of 7.5 mg and 15 mg once daily, moexipril had an antihypertensive effect comparable to that of sustained-release verapamil at doses of 180 mg and 240 mg once daily.
