Abstract
This article provides a narrative review of recent developments in mood-stabilizing drugs, considering their mechanism of action, efficacy, safety, and therapeutic potential in the treatment of mood disorders, particularly bipolar disorder and schizophrenia. The review focuses on the mechanism and clinical aspects of second-generation antipsychotic medications; aripiprazole, classified as a third-generation antipsychotic medication; lamotrigine, as a representative of antiepileptic drugs; and lurasidone, a novel second-generation antipsychotic medication. Moreover, the article refers to one of the newest and most highly effective normothymic drugs, cariprazine. The potential of new mood stabilizer candidates lumateperone and brexpiprazole is also presented. Covered topics include the clinical efficacy of new drugs in reducing manic and depressive symptoms during acute episodes, as well as their role in preventing relapse. In addition, we analyzed the incidence of adverse effects of each drug. Many of the new drugs have strong potential to be beneficial and safe in cases of many comorbidities, as they do not cause many adverse effects and do not require high doses of use. The results underscore the importance of ongoing and future research to better understand the action and efficacy of these mood stabilizers and their implications in the treatment of mood disorders, aiming to achieve euthymia and improve the quality of life of affected patients. In this article, we aim to review current drug treatments for the management of mood disorders, including bipolar disorder and schizophrenia.
