Abstract

Bipolar disorder is a complex mood disorder characterized by alternating episodes of depression and mania/hypomania, affecting approximately seven million people in the United States. Current pharmacological treatments include lithium, anticonvulsants, and second-generation antipsychotics, but these medications are often associated with significant side effects and poor adherence. Ketamine, a noncompetitive NMDA antagonist, has recently gained attention as a potential treatment for bipolar disorder due to its rapid antidepressant effects, particularly in treatment-resistant mood disorders. This article examines the therapeutic potential of ketamine for bipolar disorder, focusing on its mechanism of action and efficacy. Clinical studies have shown promising results, with ketamine rapidly alleviating depressive symptoms in patients with bipolar disorder. However, evidence for its efficacy in treating manic symptoms remains limited. Short-term side effects, including mild dissociation and hypertension, are generally transient, but concerns about long-term safety, addiction risk, and cognitive impairment warrant further investigation. Key challenges in ketamine treatment include variability in patient response, short duration of effects, and lack of standardized treatment protocols. Future research should focus on ketamine derivatives, such as esketamine and GLYX-13, which may offer safer alternatives, and explore the potential for combining ketamine with other therapeutic modalities. Although ketamine shows promise as a treatment for bipolar disorder, further studies are crucial to establish its long-term safety, efficacy, and ethical application in clinical practice.
