Efficacy and tolerability of moexipril and nitrendipine in postmenopausal women with hypertension

Abstract

Objective: The aim of this study was to compare the efficacy and tolerability of the new angiotensin-converting enzyme (ACE) inhibitor moexipril and the calcium antagonist nitrendipine in postmenopausal women with mild to moderate hypertension.

Methods: After a 4-week placebo run-in period, 93 postmenopausal women (age range 44–70 years) with primary hypertension were randomized to receive moexipril 15 mg once daily or nitrendipine 20 mg once daily for 8 weeks. The mean sitting systolic (SSBP) and sitting diastolic blood pressures (SDBP) at baseline were 161.3/103.0 mmHg in the moexipril group, and 162.2/102.3 mmHg in the nitrendipine group.

Results: After the 8 weeks of treatment, the SSBP/SDBP reductions were −21.2/−15.2 mmHg in the moexipril group and −18.2/−13.6 mmHg in the nitrendipine group. Blood pressure responses were adequate in 82.2% of the moexipril-treated patients and in 80.9% in the nitrendipine-treated group.

Adverse events were more frequent with nitrendipine than with moexipril. The most common adverse events in the nitrendipine group were headache (23.4%), flushing (21.3%) and ankle oedema (14.9%). In the moexipril group the most common adverse event was cough (8.9%).

Conclusion: The results of the study suggest that moexipril and nitrendipine are equieffective in the given dosages. In the patient population of postmenopausal women, the ACE inhibitor moexipril appears to have an advantage over the calcium antagonist nitrendipine with regard to tolerability.
