The response of the noNEpinephrine (NE) sensitive cyclic AMP generating system in slices of the rat limbic forebrain after both the acute and chronic administration of the tricyclic antidepressants desipramine (DMI) and iprindole as well as electro-convulsive treatment (ECT) was investigated. Neither the basal level of cyclic AMP nor the hormonal response to NE were altered after administration of a single dose of short term treatment with DMI and iprindole. However, the administration of the antidepressants on a clinically more relevant time basis markedly reduced the sensitivity of the cyclic AMP generating system to NE. This change in sensitivity was not related to the levels of the drugs in brain. The response of cyclic AMP to NE was also reduced by ECT, but the onset of this action was shorter than that observed with the antidepressants. ECT also antagonized the enhanced response of cyclic AMP to NE following destruction of central adrenergic nerve terminals with 6-hydroxydopamine. It thus appears that the therapeutic action of tricyclic antidepressants could be related to postsynaptic adaptive changes in the sensitivity of the noradrenergic adenylate cyclase receptor system rather than to acute presynaptic events.
