title: Anti-inflammatory drugs as moderators of antidepressant effects, especially those of the selective serotonin-reuptake inhibitor class.
abstract: Large studies examining remission rates obtained by antidepressants have yielded somewhat dismal results. In the well-reported Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study, only 36.8% of patients exhibited remission with the selective serotonin-reuptake inhibitor (SSRI) citalopram and the cumulative remission rate was 67% after multiple treatments were attempted. Warner-Schmidt et al. recently published an interesting paper that suggests specific mechanisms by which anti-inflammatory drugs inhibit the antidepressant effects of SSRIs. They employed well-established mouse models of depression: the tail suspension test and the forced swim test. In their experiment, ibuprofen significantly attenuated the antidepressant-like effects of SSRIs in both tests. The authors also presented data from the STAR*D study itself. These data - demonstrating higher remission rates for depressed patients receiving citalopram without concomitant NSAIDs (55.2%) than those receiving citalopram with NSAIDs (44.5%) - serve to illustrate the potential hindering effects of anti-inflammatory drugs.
