Amoxapine and amitriptyline. I. Relative speed of antidepressant action

Speed of onset of antidepressant effect was studied in 20 depressed outpatients assigned double-blind to equipotent doses of amoxapine or amitriptyline. In counter-balanced order, each patient had 2 periods of 3 weeks on active agent interspersed with 2 similar periods of placebo control. On daily and weekly self-ratings, amoxapine was found to reduce symptoms significantly more rapidly than amitriptyline. Psychiatrist-ratings were consonant with self-reports.
