Aripiprazole belongs to the class of atypical antipsychotics [1]. These medications are primarily used to treat psychotic disorders such as schizophrenia and bipolar disorder [2].
How do atypical antipsychotics like aripiprazole work?
Aripiprazole functions as a dopamine-serotonin system stabilizer [3]. It acts as a partial agonist at dopamine D2 and serotonin 5-HT1A receptors and an antagonist at serotonin 5-HT2A receptors [3]. This mechanism is thought to help rebalance dopamine and serotonin levels in the brain, which are believed to be involved in psychosis [2].
What conditions is aripiprazole approved to treat?
Aripiprazole is FDA-approved for the treatment of schizophrenia in adults and certain pediatric patients [4]. It is also used for manic or mixed episodes associated with bipolar I disorder in adults and certain pediatric patients, as an adjunct treatment for major depressive disorder in adults, and for irritability associated with autistic disorder in pediatric patients [4].
