The role of olanzapine

Olanzapine can improve patients' negative symptoms and cognitive functions by acting on 5-hydroxytryptamine (5-HT)2 receptors and promoting the release of dopamine in the brain's acetylcholine and frontal cortex. It can also block D2 receptors in the limbic system, improve patients' positive symptoms, and achieve antipsychotic effects. Moreover, the drug is quickly absorbed after oral administration, has a long t1/2, and can continuously exert its efficacy.
