In Langendorff perfused rat hearts, nimodipine enhances coronary flow and inhibits contractility. The binding of [3H]nimodipine (160 Ci/mmol) to sarcolemma isolated from dog heart revealed a KDof 0.2 nM. d-cis-Diltiazem, but not l-cis-diltiazem, a less active stereoisomer, stimulated [3H]nimodipine (0.17 nM) binding to sarcolemmal membranes (ED50for diltiazem = 1.1 μM). In the presence of 10 μM d-cis-diltiazem, [3H]nimodipine binding sites were doubled, but there was no change in the apparent affinity. Perfused rat hearts were treated with 250 nM d-cis-diltiazem. The negative inotropic response to nimodipine was dramatically potentiated (I50, from 1.1 to 0.033 μM). The pharmacological and binding effects were observed only at 37°C. It is possible that diltiazem in some way converts low affinity to high affinity sites.
