A Review Article: Antidepressants Drugs Action on Bipolar Disorder

Bipolar disorder (BD) is a chronic psychiatric illness marked by alternating episodes of mania and depression. The management of depressive episodes in BD poses significant clinical challenges, particularly due to the potential for treatmentemergent mood switching and other complications. Antidepressant (AD) medications, including Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs), and Tricyclic Antidepressants (TCAs), are frequently employed to alleviate depressive symptoms. However, their efficacy and safety in the context of BD remain subjects of ongoing debate.This review critically evaluates the mechanisms of action, pharmacodynamic pathways, and pharmaceutical considerations related to the use of antidepressants in BD. Special attention is given to bioequivalence challenges and the role of personalized treatment strategies, offering comprehensive insights for clinicians and researchers. The goal is to support informed, evidence-based decision-making in the nuanced and often controversial application of antidepressants in bipolar disorder.
