NCIt definition : The hydrochloride salt form of cariprazine, an orally bioavailable partial agonist
of the dopamine D2 and D3 receptors, a partial agonist of the serotonin 1A (5-HT1A)
receptor, and an antagonist of the serotonin 2A (5-HT2A) and 2B (5-HT2B) receptors,
with antipsychotic activity. Although its exact mechanism of action in schizophrenia
is unknown, it has been proposed that cariprazine's antipsychotic activity is mediated
through a combination of agonist and antagonist activities at various dopamine and
serotonin receptors, particularly through its partial agonist activity at central
dopamine D2 and 5-HT1A receptors, and its antagonist activity at 5-HT2A receptor.;
