1 | Market Overview
The global antidepressants market plays a critical role in managing mental health disorders, particularly major depressive disorder (MDD), anxiety disorders, and bipolar depression. The market has grown substantially due to rising awareness, improving diagnosis rates, and the destigmatization of mental health treatment. Key trends include the emergence of rapid-acting antidepressants, novel mechanisms targeting glutamate receptors, and precision psychiatry models that utilize digital therapeutics and biomarkers. As telepsychiatry becomes mainstream and governments increase mental health budgets, pharmaceutical companies are accelerating investments in next-generation therapies and combination regimens.
