The changes in active and inactive renin after oral administration of captopril (SQ 14225) were studied in 29 hypertensive patients. Inactive renin was calculated as plasma renin activity (PRA) after cold storage (total renin) minus PRA before cold storage (active renin). The patients were divided into 2 groups, responders and non-responders, according to the response of active renin to captopril. In 9 responders, the active renin increased markedly, while the inactive renin decreased. On the other hand, in 20 non-responders, both renin activities increased only slightly. Total renin increased markedly in responders; it increased in much smaller degree but significantly in non-responders. These data suggest that captopril promotes the conversion of inactive renin to active one and augments the renin release as a whole.

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D011392 Proline A non-essential amino acid that is synthesized from GLUTAMIC ACID. It is an essential component of COLLAGEN and is important for proper functioning of joints and tendons. L-Proline,L Proline
D012083 Renin A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.

D002216 Captopril A potent and specific inhibitor of PEPTIDYL-DIPEPTIDASE A. It blocks the conversion of ANGIOTENSIN I to ANGIOTENSIN II, a vasoconstrictor and important regulator of arterial blood pressure. Captopril acts to suppress the RENIN-ANGIOTENSIN SYSTEM and inhibits pressure responses to exogenous angiotensin.
