The effect of carbamazepine (CBZ) on spontaneous secretion of prolactin (PRL) and after stimulation with thyrotropin releasing hormone (TRH) were evaluated. Volunteer subjects after acute CBZ administration, and epileptic subjects with complex partial seizures chronically treated with CBZ, were examined. In an epileptic group, CBZ did not change TRH stimulatory effect on PRL secretion. No appreciable changes of PRL spontaneous secretion were observed, and only a small increase of sleep-entrained values with preservation of the normal secretory circadian rhythm was noted, both in normal subjects and in epileptic subjects. This result could be explained by a serotoninergic activity of CBZ, because serotonin controls the nocturnal secretion of PRL. The scarcity of PRL changes produced by CBZ in these various conditions agrees with the absence of published reports of CBZ side effects associated with hyperprolactinemia.
