Clinical comparison of selective serotonin reuptake inhibitors in the treatment of geriatric depression: a review of literature

Abstract

Introduction

With their ease of administration, relatively benign side-effect profile and safety in overdose, in the United States the selective serotonin reuptake inhibitors (SSRIs) have become de facto first choice in the treatment of geriatric depression, displacing tricyclic antidepressants (TCAs). In this paper, the relevant literature regarding neurochemistry, kinetics, dosing, efficacy and differential side-effect profiles of citalopram, fluvoxamine, fluoxetine, sertraline, and paroxetine, the five currently available SSRIs in the USA, will be reviewed with special emphasis on geriatric data. Of late, considerable controversy has been generated regarding whether SSRIs are as effective as TCAs in severe and melancholic depressive subtypes. This important issue will be explored and the relative utility of all the SSRIs in the elderly patient compared and contrasted. Finally, reasons for difficulties in comparing results across studies will be elucidated.
