title: Previous chronic chlorimipramine treatment did not modify some physiological responses to acute and chronic stress in rats.
abstract: The effects of previous chronic administration of the tricyclic antidepressant drug chlorimipramine (CMI) on some physiological responses of adult male rats to stress has been studied. CMI significantly reduced food intake and body weight gain, but did not alter either adrenal weight or basal serum corticosterone levels. Corticosterone response to 1 h of immobilization stress was the same in saline and CMI-treated rats. When the rats previously treated with CMI were subjected to chronic immobilization stress, it was found that the drug did not alter the anorexic effects of the stressor, but reduced the rate of adaptation of adrenocorticotropin response to stress. These data indicate that previous chronic CMI administration does not prevent changes in the secretory activity of the pituitary-adrenal system or the reduction of food intake and body weight caused by strong stressors.
