1 Captopril, but not Ro 42-5892, increased forearm blood flow (2.4 +/- 0.8 versus 1.9 +/- 0.8 ml/min/100 ml, p less than 0.01) and significantly enhanced the increase of forearm blood flow to brachial artery infusions of bradykinin (0.15, 1.5, 5, 15, and 50 ng/min/100 ml; 5 minutes each) from 744 +/- 632% to 1,383 +/- 514% (p less than 0.01). Captopril kininogen 1 Homo sapiens
2 Furthermore, repeat bradykinin infusions resulted in further decreases of blood pressure (from mean pressure of 71.4 +/- 8.5 to 63.2 +/- 7.6 mm Hg, p less than 0.01) only after captopril. Captopril kininogen 1 Homo sapiens
3 Changes of blood pressure after captopril were unrelated to baseline plasma renin activity but correlated with captopril-induced enhancement of vasodilation to bradykinin (r = 0.68, p less than 0.05). Captopril kininogen 1 Homo sapiens
4 Changes of blood pressure after captopril were unrelated to baseline plasma renin activity but correlated with captopril-induced enhancement of vasodilation to bradykinin (r = 0.68, p less than 0.05). Captopril kininogen 1 Homo sapiens
