The anti-inflammatory mechanism of antidepressants - SSRIs, SNRIs

The cytokine theory of depression no longer brings about any doubts. Experiments and research studies conducted in the last ten years have confirmed that both physical and psychological (emotional) stress increases the likelihood of occurrence of mental disorders (including depressive disorders) owing to the action of a series of hormonal and biochemical mechanisms. Selective serotonin reuptake inhibitors (SSRI) as well as serotonin and norepinephrine reuptake inhibitors (SNRIs) are some of the most commonly applied drugs in the world during pharmacotherapy of recurrent depressive disorder. The underestimated anti-inflammatory and anti-oxidative effect may be one of the potential mechanisms of action of the preparations mentioned above. The detailed specificity of action of this mechanism still remains unknown. The aim of our work will be to perform a review of contemporary literature in order to present the latest scientific reports regarding the anti-inflammatory effects of SSRIs and SNRIs. The mechanism of anti-inflammatory action may serve as a possible explanation for the efficacy of antidepressants from the groups of SSRIs and SNRIs.
