Aripiprazole is an atypical antipsychotic that has both dopamine and serotonin receptors activity. It is a partial agonist of dopamine D2 receptors that relieves the symptoms of schizophrenia. It is characterized as a dopamine system stabilizer. It is a potent partial agonist at serotonin 5-HT1A receptors and antagonist at 5-HT2A receptors. This is associated with improvement of depressive, cognitive and negative symptoms.
