Cyp450 1a2 inducers
WebCYP1A2 is primarily responsible for olanzapine's metabolism and this can be impacted by CYP1A2 inducers (cigarette smoke) or inhibitors. 4. Quetiapine is a dibenzothiazepine derivative. Like clozapine, it has relatively low affinity for D 2 receptors (30% binding) compared to other antipsychotics (60–80%).
