REXULTI® (Brexpiprazole) Tablet is an Atypical Antipsychotic as a “Serotonin-Dopamine Activity Modulator” (SDAM) that combines partial agonist activity at serotonin 5-HT1A and at dopaminergic D2 receptors with antagonist activity at serotonergic 5-HT2A receptors, with similar high affinities at all of these receptors (Ki: 0.1 nM to 0.5 nM).
Brexpiprazole also shows antagonist activity at noradrenergic α1B/2C receptors with affinity in the same sub-nanomolar Ki range (Ki: 0.2 nM to 0.6 nM).
