title: Hormonal responses to zimelidine and desipramine in depressed patients.
abstract: Plasma prolactin (PRL), growth hormone (GH), luteinizing hormone (LH), and cortisol were repeatedly measured during the morning over a 4-hour period in patients who received single or chronic doses of desipramine (DMI) or zimelidine (ZIM). Preclinical studies had suggested that DMI, an uptake inhibitor specific for norepinephrine, would have different effects than ZIM, a selective serotinin uptake inhibitor. The GH response to DMI was blunted in the depressed patients. Neither DMI nor ZIM produced changes in LH or cortisol. DMI acutely increased plasma PRL, whereas ZIM had an effect only after chronic pretreatment. Chronic DMI but not ZIM increased baseline PRL. The patterns and magnitude of responses raise questions concerning the role of serotonin and norepinephrine in PRL release in man and the applicability of current preclinical models.
