Desipramine and fenfluramine were administered to bulimic patients in a 15-week study of double-blind, placebo-controlled, crossover design. The 22 patients in the study met DSM-III criteria for bulimia and were of normal weight. Twelve subjects were randomly allocated to the fenfluramine group, and 10 subjects received desipramine. Half the subjects in each group received the active drug in the first 6 weeks and half received placebo. There was a 3-week washout period, after which subjects were crossed over for the remaining 6 weeks. The Eating Disorder Inventory, Profile of Mood States, bulimia symptom checklists, and Hopkins Symptom Checklist were administered at weeks 0, 2, 4, 6, 9, 11, 13, and 15. Subjects maintained a daily record of bingeing, vomiting, and laxative/diuretic abuse. Results indicated that both drugs had beneficial effects on bingeing and vomiting frequency, although a greater proportion of patients were identified who responded to fenfluramine than to desipramine. Fenfluramine and desipramine were also effective in reducing the psychological symptoms of bulimia, such as the urge to binge, and feelings of depression. Results suggest that direct alteration of central food intake regulatory centers can effectively control bulimia.(J Clin Psychopharmacol 1988; 8: 261–269)

N RECENT years, several controlled studies have reported that normal weight bulimia responds favorably to antidepressant medication. The tricyclic antidepressants? as well as the monoamine oxidase inhibitorsº* have been found effective in reducing the cardinal symptoms of bulimia (bingeing and purging), and are also reported to be effective in alleviating the depressive symptoms that often accompany normal weight bulimia. Antidepressants appear effective in
