Abstract
Total and active renin were measured in plasma of 6 normal volunteers before and after acute and sustained angiotensin converting enzyme (ACE) inhibition with CGS 14824A (2 mg and 10 mg p.o. q.d.) or placebo treatment. The same sandwich technique was used for the measurement of both total and active renin using a polyacrylamide-iron-oxide linked monoclonal antibody to trap renin and 125I-labelled second monoclonal antirenin antibodies without or with specificity for active renin. Normal values for supine subjects ranged for active renin between less than 3 pg/ml and 28 pg/ml and for total renin between 73 and 263 pg/ml. Plasma ACE activity was clearly suppressed during 24 hours following both 2 mg and 10 mg CGS 14824A. Active plasma renin reached 6- and 12-fold normal values on days 1 and 7 of treatment with the 10 mg dose. Total renin rose to 150% and 228% respectively at the same time. Inactive renin continued rising during the first day of 10 mg CGS treatment to a final 141% at 24 hours post-drug and didn't change on day 7. Plasma renin activity correlated well with active renin levels (r = 0.92). We conclude that both total and active plasma renin concentrations can now be directly measured with great accuracy within 6 hours.
