Abstract:
:This study assesses the magnitude and duration of action of three different oral doses of the new orally active angiotensin-converting enzyme (ACE) inhibitor RO 312848 (cilazapril, Hoffman-LaRoche, Nutley, NJ) on blood pressure and plasma ACE levels. Twelve hypertensive patients were separated into two groups: Group A (n = 6) received two single daily doses of 5 and 10 mg, each preceded and followed by two placebo days, and Group B (n = 6) received 10 and 20 mg on an identical protocol. The onset and duration of an appreciable blood pressure lowering effects were at 2 hours and at least for 12 hours, respectively, whereas suppression of ACE levels occurred at 1 hour and lasted for more than 72 hours. Response of these two parameters was partial after 5 mg, but was maximal after 10 mg and did not increase further with the 20-mg dose. A 5-10 mg dose daily may be sufficient to maintain chronic blood pressure control with this agent, but long-term dose trials are necessary to establish its clinical utility.
