OBJECTIVE This study was done to compare the effects of 6-week treatment with amitriptyline on hypothalamic-pituitary-adrenocortical (HPA) regulation in elderly depressed patients and age-matched comparison subjects. METHODS A combined dexamethasone-suppression/CRH-stimulation (dexamethasone/CRH) test was administered before initiation of amitriptyline treatment and at the end of weeks 1, 3, and 6 of treatment. Thirty-nine depressed inpatients, mean age = 69 years, completed the study. Fourteen normal volunteers, mean age = 67 years, served as comparison subjects. RESULTS In relation to the comparison subjects, the depressed patients had a profoundly abnormal HPA response, in particular an exaggerated cortisol release in the dexamethasone/CRH test. This abnormality began to disappear after 1 week of treatment with amitriptyline. In contrast, amitriptyline did not affect neuroendocrine regulation in the comparison subjects at any time during the test period. CONCLUSIONS The data suggest that amitriptyline affects HPA regulation in hypercortisolemic depression only, and they raise the possibility that normalization of its feedback control is related to the antidepressive effect of amitriptyline.

D003346 Corticotropin-Releasing Hormone A peptide of about 41 amino acids that stimulates the release of ADRENOCORTICOTROPIC HORMONE. CRH is synthesized by neurons in the PARAVENTRICULAR NUCLEUS of the HYPOTHALAMUS. After being released into the pituitary portal circulation, CRH stimulates the release of ACTH from the PITUITARY GLAND. CRH can also be synthesized in other tissues, such as PLACENTA; ADRENAL MEDULLA; and TESTIS.
