Anhedonia is a condition in which the capacity to experience pleasure is totally or partially lost. Although anhedonia is a feature of major depressive disorder according to DSM IV criteria for major depression diagnosis, so far it has received relatively little attention. The scale that is most commonly used in the measurement of anhedonia is the Snaith-Hamilton Pleasure Scale (SHAPS), a brief 14-item self-report questionnaire designed to measure hedonic tone and its absence. Two studies have described the efficacy of agomelatine in the treatment of anhedonia: an open-label study and a comparative trial versus the antidepressant venlafaxine XR. In both studies agomelatine significantly reduced anhedonia, as indicated using the SHAPS. This reduction was observed after the first week of treatment (P<0.05) and at different times until the end of the trial. Moreover, in the comparative trial, a significant difference between groups was observed in favor of agomelatine, after 1 (P<0.05), 2 (P<0.01), and 8 weeks (P<0.01). The possible effect of agomelatine on anhedonia may represent a novel area of interest among antidepressant agents and deserves further investigation, with larger samples and double-blind placebo-controlled designs.
