DRUG INTERACTION Aripiprazole is known to interact with other drugs like carbamazepine, ketoconazole, quinidine, fluoxetine or paroxetine ethanol. Always consult your physician for the change of dose regimen or an alternative drug of choice that may strictly be required. MECHANISM OF ACTION Aripiprazole's antipsychotic activity is likely due to a combination of antagonism at D2 receptors in the mesolimbic pathway and 5HT2A receptors in the frontal cortex. Antagonism at D2 receptors relieves positive symptoms while antagonism at 5HT2A receptors relieves negative symptoms of schizophrenia.
