Description

A tricyclic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent. [PubChem]

Pharmacology

Indication

For use in patients with treatment-resistant schizophrenia.

Associated Conditions
Pharmacodynamics

Clozapine is a psychotropic agent belonging to the chemical class of benzisoxazole derivatives and is indicated for the treatment of schizophrenia. Clozapine is a selective monoaminergic antagonist with high affinity for the serotonin Type 2 (5HT2), dopamine Type 2 (D2), 1 and 2 adrenergic, and H1 histaminergic receptors. Clozapine acts as an antagonist at other receptors, but with lower potency. Antagonism at receptors other than dopamine and 5HT2 with similar receptor affinities may explain some of the other therapeutic and side effects of Clozapine. Clozapine's antagonism of muscarinic M1-5 receptors may explain its anticholinergic effects. Clozapine's antagonism of histamine H1 receptors may explain the somnolence observed with this drug. Clozapine's antagonism of adrenergic a1 receptors may explain the orthostatic hypotension observed with this drug.

Mechanism of action

Clozapine's antipsychotic action is likely mediated through a combination of antogistic effects at D2 receptors in the mesolimbic pathway and 5-HT2A receptors in the frontal cortex. D2 antagonism relieves positive symptoms while 5-HT2A antagonism alleviates negative symptoms.
