Objective: The aim of this study was to evaluate the efficacy of fluvo
xamine in the treatment of delusional depression. Method: Fifty-nine i
npatients who met the DSM-III-R criteria for major depression with psy
chotic features were treated with fluvoxamine for 6 weeks. Patients we
re assessed at baseline and weekly thereafter with the Hamilton Depres
sion Rating Scale and the Dimensions of Delusional Experience rating s
cale. Results: Of the 57 subjects who completed the trial, 84.2% (N=48
) recovered. The inner episodes of the patients who did not respond to
fluvoxamine were of significantly longer duration than those of the r
esponders. Conclusions: Fluvoxamine has a response rate similar to tha
t of the currently most efficacious treatments for delusional depressi
on, including antidepressants plus antipsychotics and ECT.
