The structurally novel Ca2+ channel blocker Ro 40-5967, which binds to the [3H] desmethoxyverapamil receptor, is devoid of the negative inotropic effects of verapamil in normal and failing rat hearts

Abstract

Ro 40-5967 is a structurally novel Ca2+ channel blocker that binds to the verapamil-type receptor of cardiac membranes but that has been shown in isolated guinea-pig hearts to be about ten times less potent a negative inotropic agent than verapamil. The goals of the present study were to confirm these findings in vitro in isolated perfused rat hearts as… (More)
