How does olanzapine work (mechanism of action)? Olanzapine belongs to a group of medicines called second-generation (atypical) antipsychotics. It is thought to work by balancing brain chemicals called serotonin and dopamine. These chemicals are known to affect thoughts and mood. ...
Olanzapine belongs to a drug class known as atypical antipsychotics. Other members of this class includeclozapine(Clozaril),risperidone(Risperdal),aripiprazole(Abilify) andziprasidone(Geodon). The exact mechanism of action of olanzapine is not known. It may work by blocking receptors for several neuro...
12.1 Mechanism of Action The mechanism of action of olanzapine, in the listed indications is unclear. However, the efficacy of olanzapine in schizophrenia could be mediated through a combination of dopamine and serotonin type 2 (5HT2) antagonism. 12.2 Pharmacodynamics Olanzapine binds with high affi...
The exact mechanism of action of olanzapine is not known. It may work by blocking receptors for several neurotransmitters (chemicals that nerves use to communicate with each other) in the brain. It binds to alpha-1, dopamine, histamine H-1, muscarinic, and serotonin type 2 (5-HT2) ...
Olanzapine's exact mechanism of action as a therapeutic agent in schizophrenia is relatively unknown, but it is considered to act as an antagonist to dopamine D2 receptors along with rapid ligand-receptor dissociation kinetics which helps to decrease extrapyramidal symptoms [16]. Along with it ...
The mechanism of action of olanzapine relies on its higher affinity for 5-HT2A serotonin receptors than D2 dopamine receptors, which are antagonised by the molecule. In addition to that, the antagonism of 5HT2C receptors may contribute to reduce cognitive and affective symptoms in some patients ...

Mechanism of ActionDopamine D1 receptor antagonists; Dopamine D2 receptor antagonists; Opioid mu receptor antagonists; Serotonin 5-HT2A receptor antagonists Orphan Drug Status Orphan designation is assigned by a regulatory body to encourage companies to develop drugs for rare diseases. ...
O lanzapine is classed as an atypical antipsychotic and is considered a firstline agent in the management of newly diagnosed psychosis. It has a similar mechanism of action to classical antipsychotics but with a lower incidence of adverse events. O lanzapine rarely produces hypotension and has les...
Mechanism of action The atypical antipsychotics mostly block receptors in the brain's dopamine pathways. In the olanzapine/fluoxetine combination drug, fluoxetine inhibits serotonin reuptake in the synapse by binding to the reuptake pump on the neuronal membrane. This increases serotonin availab...
