Chronic treatment with antidepressants potentiates the behavioural sensitivity to the administration of dopamine receptor agonists.

Abstract

Chronic treatment with antidepressants potentiates the behavioural sensitivity to the administration of dopamine receptor agonists. Such supersensitivity might be involved in the mechanism of action of antidepressant drugs, but it has also been suggested to play a role in the mechanisms underlying antidepressant treatment-related mania (i.e. antidepressant-induced mood switch and rapid cycling). Consistently to this hypothesis, we have recently shown that lithium salts, which are poorly effective in antidepressant-related mania, fail to prevent the development of imipramine-induced supersensitivity to the locomotor effect of the dopamine D2-like receptor agonist quinpirole. In the present paper, we report the ability of carbamazepine, an anticonvulsant with antimanic and mood stabiliser properties, to prevent the development of supersensitivity to the locomotor response to quinpirole induced by chronic treatment with imipramine. The present results, together with the results of our previous study, might contribute to explain the different responsiveness to lithium and carbamazepine observed in some manic patients, and are consistent with the clinical data suggesting that carbamazepine might be more effective than lithium in antidepressant-related mania. © 2001 Elsevier Science B.V.
