Chronic co-administration of nifedipine and ECT or imipramine results in an increase in responsiveness of cerebral cortical alfa1-adrenoceptor as measured by accumulation of inositol phosphate in cortical slices after noradrenaline stimulation; the responsiveness of beta-adrenoceptor, measured by accumulation of cyclic AMP, was depressed similarly by antidepressant treatment with and without nifedipine.
