title: Antihypertensive treatment with moexipril plus HCTZ vs metoprolol plus HCTZ in patients with mild-to-moderate hypertension.
abstract: Combination therapy with the new ACE inhibitor moexipril plus hydrochlorothiazide (HCTZ) results in significant blood pressure (BP) reductions. This study compares the efficacy and safety of moexipril plus HCTZ to that of a standard combination treatment in patients with mild-to-moderate hypertension. After a 1 month placebo run-in period, 140 hypertensive patients whose sitting diastolic BP (DBP) averaged 95-114 mm Hg were randomized to receive either once daily moexipril 7.5 mg/HCTZ 12.5 mg or metoprolol 100 mg/HCTZ 12.5 mg for the following 12-week double-blind treatment period. At biweekly visits BP was controlled sphygmomanometrically and the occurrence of adverse events (AE) was documented. At study endpoint adjusted mean reductions in sitting systolic/diastolic BP seen with both combinations were -17.6 mm Hg/-12.8 mm Hg and -17.2 mm Hg/-13.9 mm Hg in the moexipril/HCTZ and metoprolol/HCTZ groups, respectively. The response rate to both kinds of combinations were very similar, 69% and 74% in the moexipril/HCTZ and metoprolol/HCTZ groups, respectively. The percentage of patients which experienced one or more AEs were 46% in the moexipril/HCTZ and 61% in the metoprolol/HCTZ group. Headache and cough which are the most frequently reported AEs after treatment with ACE inhibitors were seen in 9% and 10% of the patients in the moexipril/HCTZ group compared to 10% and 4% in the metoprolol/HCTZ group. The study indicates that the combination of moexipril 7.5 mg plus HCTZ 12.5 mg is as efficacious and safe as metoprolol 100 mg plus HCTZ 12.5 mg in the treatment of mild-to-moderate hypertension.
