Acute Effects of Captopril on Serum Angiotensin-Converting Enzyme Activity, the Renin-Aldosterone System and Blood Pressure in Patients with Sarcoidosis

Abstract

MIZUNO, K., GOTOH, M., MATSUI, J., NAGASAWA, S. and FUKUCHI, S. Acute Effects of Captopril on Serum Angiotensin-Converting Enzyme Activity, the Renin-Aldosterone System and Blood Pressure in Patients with Sarcoidosis. Tohoku J. exp. Med., 1983, 140 (1), 107-108-Captopril, an orally active angiotensin-converting enzyme (ACE) inhibitor, was administered to three patients in an active stage of sarcoidosis. The serum ACE level, aldosterone concentration in plasma and blood pressure decreased rapidly after administration, while plasma renin activity was not significantly changed. It is suggested that inhibition of ACE by captopril offers a possible therapeutic approach to the treatment of sarcoidosis.
