-Mechanism of action of brexpiprazole compared with aripiprazole
-Brexpiprazole Side effects compared to Aripiprazole side effects
Brexpiprazole is a :
•Partial agonist of dopamine D2 receptors that is at a lower level of intrinsic activity than aripiprazole.
•Partial agonist at serotonin 5-HT1A that is at a stronger level of activity than aripiprazole.
•Potent antagonist of serotonin 5-HT2A receptors.
•Potent antagonist of noradrenaline alpha1B/2C receptors.
•Moderate affinity for histamine H1 receptors

Brexpiprazole has a lower incidence of akathisia than aripiprazole.
It has a long half-life of 86-91 hours.
It has minimal impact on prolactin levels.
It is metabolised by CYP2D6 and CYP3A4 enzymes.
