Tricenter assessment of the efficacy of the ACE inhibitor, moexipril, by ambulatory blood pressure monitoring.
To assess the efficacy and time-dependent effects of once-daily moexipril, a nonsulfhydryl ester prodrug of the angiotensin-converting enzyme (ACE) inhibitor, moexiprilat, we conducted a multicenter, double-blind, placebo-controlled trial in 51 hypertensive patients using both clinic and ambulatory blood pressure (BP) recordings. Patients were included in the trial based on a minimum of 40% of the daytime diastolic BPs of 90 mm Hg or more during a placebo baseline phase; and the primary endpoint was change in 24-hour ambulatory diastolic BP. Patients were randomized to receive placebo, 7.5 mg of moexipril, or 15 mg of moexipril once daily. Clinic and ambulatory BPs were taken on the first day and after eight weeks of double-blind therapy. After the 7.5-mg dose, there were no significant changes in the acute or prolonged clinic BPs compared with placebo. Compared with adjusted mean changes for placebo, the 15-mg moexipril dose lowered clinic systolic BP, but not diastolic BP. In contrast, acute (1 day) reductions in 24-hour diastolic BPs were -2/-3 mm Hg, -6/-4 mm Hg, and -14/-9 mm Hg on placebo, 7.5 mg of moexipril, and 15 mg of moexipril, respectively (P < .01 for the 15-mg dose). Similarly, after long-term dosing for 8 weeks, reductions in 24-hour diastolic BPs were 1/-2 mm Hg, -6/-4 mm Hg, and -12/-9 mm Hg for the respective treatment groups (P < .01 for the 15-mg dose).(ABSTRACT TRUNCATED AT 250 WORDS)[1]References
