1 Verapamil infusion (0.004 mg X kg-1 X min-1) into the renal artery of uninephrectomized dogs with an intact kidney resulted in significant increases (P less than 0.05) in renal blood flow, creatinine clearance, and the excreted fractions of Na+ and Cl-; renin secretion decreased (P less than 0.05) and plasma aldosterone did not change. Verapamil renin Canis lupus familiaris
2 Conversely, renal arterial infusion of verapamil in dogs with nonfiltering, denervated, papaverine-treated kidneys resulted in no change in renal blood flow and a significant increase (P less than 0.05) in renin secretion. Verapamil renin Canis lupus familiaris
3 The disparate effects of verapamil on renin secretion from intact and nonfiltering kidneys may be due to actions of the Ca2+ channel blocker on renal hemodynamic and/or renal tubular mechanisms in the intact kidney that mask a direct effect of verapamil on renin-secreting cells. Verapamil renin Canis lupus familiaris
