Mechanism of action

Brexpiprazole modulates dopaminergic and serotonergic neurotransmission through multiple receptor interactions. As a partial agonist at D2 receptors, it reduces excessive dopamine signaling in psychotic states while maintaining baseline dopaminergic tone. Its 5-HT1A partial agonism and 5-HT2A antagonism contribute to anxiolytic and antidepressant effects, making it suitable for treating schizophrenia and major depressive disorder.
