Utibapril significantly inhibits plasma, renal, and vascular ACE but not ventricular ACE activity. Utibapril (2 μg/kg/day) significantly inhibits vascular ACE activity, and Utibapril (250 μg/kg/day) results in a significant inhibition of plasma ACE. Furthermore, angiotensin I-induced decreases in coronary flow in the isolated heart are significantly inhibited after treatment with the higher doses of utibapril. FPL 63547 is rapidly and extensively excreted as the diacid in the bile but appeared in the urine in negligible amounts.
