Olanzapine is an antipsychotic medication that interacts with multiple receptors, including serotonin (5HT2A/2C, 5HT3, 5HT6), dopamine (D1-D5), muscarinic (M1-M5), adrenergic (α1), and histamine (H1). While its exact mechanism in treating schizophrenia is not fully understood, it is believed to work by blocking dopamine and serotonin (5HT2) receptors. Olanzapine is efficiently absorbed after oral intake, reaching peak levels in 5-8 hours, and food intake does not affect its absorption. Studies have found that Olanzapine does not cause genetic mutations, chromosomal damage, or cancer.
