The present study was done to investigate the role of endogenous prostaglandins in the mechanism of renin release stimulated by angio-tensin I-converting enzyme inhibitor, SQ 14225 in 9 hypertensive patients and 3 normotensive subjects. Plasma renin activity was significantly i increased after the administration of SQ 14225 and decreased to control levels after the addition of indomethacin. Pre-treatment with indomethacin also inhibited the augmentation of renin release following the SQ 14225 administration. Urinary excretion of prostaglandin E was not significantly increased after the SQ 14225 administration but significantly decreased after the administration of indomethacin. The present data that the augmented renin release due to the suppression of the negative short feedback mechanism of renin release by SQ 14225 was inhibited by indomethacin suggest that endogenous prostaglandin system may contribute to the short feedback mechanism of renin release.
