Background Brexpiprazole has been registered in the Netherlands and Belgium for the treatment of schizophrenia since 2019. It is a third-generation antipsychotic drug with a number of pharmacological similarities to aripiprazole and cariprazine. Aim To critically evaluate the pharmacology, effectiveness and side effects of brexpiprazole in the treatment of schizophrenia using the hitherto available double-blind, placebo-controlled study. Method A clinically oriented study of the literature. Results Brexpiprazole is effective in the treatment of schizophrenia and has few extrapyramidal side effects, metabolic side effects and moderate weight gain, no QTc prolongation, no sedation, and little influence on blood prolactin levels. Limited dose titration is required when initiated on brexpiprazole. Conclusion Brexpiprazole is a treatment option for schizophrenia, with a relatively favorable side effect profile. The position of brexpiprazole within the current treatment algorithm should become clear through future research and clinical experience. Tijdschrift voor Psychiatrie 63(2021)1, 48-55
