[Efficacy of benazepril monotherapy in moderate essential hypertension studied by automatic ambulatory blood pressure monitoring].

Abstract

Authors examined the effects of benazepril, regarding the length of effectiveness by ambulatory blood pressure monitoring (ABPM), drug tolerable, and the compliance of patients in mild to moderate essential hypertension. 14 patients were treated with benazepril monotherapy. Six of them were newly diagnosed, and the rest had already been treated for hypertension. At the start, after six and 12 weeks, 24-hour monitoring was performed. Casual blood pressure (BP) measurements and detection of side-effects were also performed at 3rd and 9th-week. Prior the study the average daytime BP measured by ABPM was 149.1 +/- 7.7/96.6 +/- 4.7 mmHg. 10 mg of benazepril was first administered in the morning. By the end of the sixth week the average BP was significantly decreased (daily average: 139.1 +/- 9.9/88.2 +/- 7.6 mmHg). The daytime diastolic average BP of 8 patients was lower than 90 mmHg and the other's daily dose was raised to 20 mg. During the 12th-week we found optimal tension in 11 patients, while in two others there was also a significant decrease. The daily average BP was 134.7 +/- 7.5/85.6 +/- 6.6 mmHg. In comparison the data at the beginning of the study here was significant decrease in the 24-hour, daytime and night-time BP, in the hypertension time-index and the hyperbaric impact, both in systolic and diastolic levels. During the 12th-week period the diurnal index was unchanged. The early morning BP decreased by the end of the 3rd month from 148.6 +/- 14.1/98.5 +/- 11.7 mmHg to 135.2 +/- 13.5/93.4 +/- 11.2 mmHg. Sustained side-effect did not occur. The patient's compliance to benazepril was excellent. Authors conclude that benazepril monotherapy lowered in 92.8%, and normalized in 78.5% the blood pressure of patients suffering from mild to moderate essential hypertension. The unchanged diurnal index, and the decrease in the early morning blood pressure suggest the 24-hour effect of benazepril.
