Olanzapine is an atypical antipsychotic, used for the treatment of schizophrenia and bipolar disorder. Olanzapine is structurally similar to clozapine and quetiapine. It is a dopamine antagonist and is classified as a thienobenzodiazepine. Olanzapine has a higher affinity for 5-HT2A serotonin receptors than D2 dopamine receptors, which is a common property of all atypical antipsychotics, aside from the benzamide antipsychotics such as amisulpride. Olanzapine also had the highest affinity of any second-generation antipsychotic towards the P-glycoprotein in one in vitro study.
