Global Trends in the Use of Pharmacotherapy for the Treatment of Bipolar Disorder.

Bipolar Disorder (BD) is a chronic mental health condition characterized by significant mood swings, including periods of mania or hypomania and depression. Affecting approximately 1-2% of the global population, BD is associated with impaired social functioning, decreased quality of life, and an increased risk of suicide. The disorder presents a substantial burden on healthcare systems and imposes significant economic costs due to lost productivity and the need for extensive treatment and support services. This comprehensive review synthesizes global trends in BD pharmacotherapy over the past 1 to 3 years, focusing on emerging medications, novel treatment protocols, and ongoing debates within the field. Additionally, the review explores differences in prescribing patterns across developed and developing countries, introduces the impact of pharmacogenomics and personalized medicine on treatment outcomes. PURPOSE OF REVIEW: The primary purpose of this review is to provide a comprehensive and up-to-date synthesis of the global trends in the use of medications for the treatment of BD over the past 1 to 3 years. This review aims to outline the latest studies, clinical trials, and meta-analyses relevant to BD pharmacotherapy, highlighting new discoveries and advancements. Furthermore, this review will address ongoing debates and controversies in the field, such as the role of antidepressants in BD treatment and the long-term use of antipsychotics, aiming to bridge knowledge gaps and guide future research directions. RECENT FINDINGS: Studies continue to reinforce the efficacy of lithium in mood stabilization and reduction of suicidal behavior, despite its declining use due to safety concerns. Mood stabilizing anticonvulsants like valproate and carbamazepine continue to be vital alternatives, each with distinct side effect profiles necessitating careful patient monitoring. The approval and increasing use of novel atypical antipsychotics, such as lurasidone (2013) and cariprazine (2015), has expanded treatment options, offering efficacy in different phases of BD with relatively favorable side effect profiles. Antidepressants remain contentious, with evidence suggesting their benefits primarily when used in combination with mood stabilizers. Emerging agents like lumateperone (Dec 2021) and esketamine show promise, while pharmacogenomic research is paving the way for more personalized treatments. The landscape of BD pharmacotherapy is marked by significant advancements and ongoing challenges. Lithium and mood stabilizing anticonvulsants remain foundational treatments, albeit with adherence challenges and side effect concerns. The advent of new atypical antipsychotics and novel agents offers promising therapeutic options, while antidepressants continue to be debated. Personalized medicine and pharmacogenomics could emerge as transformative approaches, allowing for more tailored and effective treatments. However, disparities in medication accessibility between developed and developing countries highlight the need for global collaboration to optimize BD management. Continued research and innovation are essential to addressing the complexities of BD and improving patient outcomes worldwide.
