Thirty-three moderately depressed outpatients were enrolled in a doubl
e-blind, randomized 7-week study comparing fluvoxamine maleate, a sele
ctive serotonin reuptake inhibitor, with the tricyclic antidepressant
amitriptyline. The mean drug dosages at the end of the study were 175
mg/day of fluvoxamine and 135 mg/day of amitriptyline. The majority of
patients showed significant improvement in scores on the Hamilton Rat
ing Scale for Depression and the Clinical Global Impression scale from
study initiation to termination, with no statistically significant di
fferences between drugs. There was no difference in the number of side
effects noted with the two antidepressants, although more subjects in
the amitriptyline group (6/17; 35.3%) withdrew from the study (becaus
e of adverse effects) than in the fluvoxamine group (3/16; 18.8%).
