What is the mechanism of action of clozapine?
Mechanism of Action The mechanism by which clozapine exerts its effects involves the blocking of 5-HT2A/5-HT2C serotonin receptors and the D1-4 dopamine receptors, with the highest affinity for the D4 dopamine receptor.
How does clozapine work in the brain?
Clozapine reduces dopamine activity where it is too high, helping with symptoms like hallucinations. It also adjusts dopamine levels in other areas of the brain to improve focus and concentration.
What receptors does clozapine work?
The antipsychotic basis of clozapine is to transiently occupy dopamine D2 receptors in the human striatum, in contrast to haloperidol and chlorpromazine, which have a prolonged occupation of D2 receptors. The chemical structure of clozapine facilitates a relatively rapid dissociation from D2 receptors.

Clozapine has also been reported to produce fewer parkinsonian symptoms, to involve a lower risk of producing tardive dyskinesia, and to produce no serum prolactin elevations in man.
