There are very divergent appraisals of the effect of antidepressants on thy
roid parameters and their possible correlation with the response. Whereas t
here are numerous investigations of tricyclic antidepressants, so far, ther
e are only limited data on the possible effect of serotonin-selective reupt
ake inhibitors on neuroendocrine parameters. The present study showed a sig
nificant reduction of 11.2% in thyroxine during treatment with 20 mg paroxe
tine in 25 severely depressed patients. Copyright (C) 2000 S. Karger AG, Ba
