β¦ Synopsis
We have studied the acute and chronic effects of an ACE inhibitor (captopril) on platelet function and the renin-angiotensin system in patients with congestive heart failure. Plasma concentrations of angiotensin II fell significantly after a single dose of captopril (25 mg) and during long-term treatment with captopril (2 weeks, 75 mg/day). Plasma renin activity increased significantly after both the single and repeated doses. Captopril did not affect ADP-induced platelet aggregation or concentrations. It seems unlikely that circulating angiotensin II affects ADP-induced platelet aggregation in patients with congestive heart failure.

Objective: The pharmacokinetics and pharmacodynamics of buffered sublingual captopril were assessed in patients with congestive heart failure (CHF). Methods: The study was carried out in a randomised single-blind cross-over fashion (n = 6, 4 males and 2 females) and involved two study days, at least
Angiotensin converting enzyme inhibitors have greatly improved the treatment of patients with chronic heart failure but they are not effective in all patients, and their use may be limited by side effects. There is, therefore, a need to investigate new drugs and to compare their efficacy with angiot
