Aripiprazole is prescribed for schizophrenia in adults and adolescents aged 13 and older.

How does aripiprazole work?
Aripiprazole functions as a partial agonist at dopamine D2 and serotonin 5-HT1A receptors, and as an antagonist at serotonin 5-HT2A receptors. This mechanism is thought to modulate dopaminergic and serotonergic neurotransmission, which are implicated in the symptoms of psychosis and mood disorders [1].
