title: Effects of angiotensin I-converting enzyme inhibitor (SA-446) on renal function in dogs.
abstract: The effects of an orally active inhibitor of angiotensin-converting enzyme (SA-446) on systemic arterial pressure, renal function and renin release were examined in anesthetized dogs. Intrarenal infusion of the larger dose of SA-446 (0.1 mg/min) caused an increase in RBF, urine flow and renin release and caused a fall in blood pressure. The smaller dose of SA-446 (0.02 mg/min) did not affect the blood pressure, but it increased the urine flow. However, the same dose of SA-446 in combination with probenecid caused a significant fall in blood pressure. The potentiation of SA-446 with probenecid may be explained by the elevation in plasma SA-446 concentration via the inhibition of its tubular secretion by probenecid.
