Description

Application

N-Desmethylclozapine has been used as standard to quantify the clozapine plasma levels in treatment-refractory Chinese schizophrenic patients.

Biochem/physiol Actions

N-Desmethylclozapine serves as an agonist to muscarinic acetylcholine receptors, and is known to exert its antipsychotic action. It blocks synaptic transmission by antagonizing synaptic GABA (γ-aminobutyric acid) receptors.

Major metabolite of clozapine; potent 5-HT₂ serotonin receptor antagonist and a ligand for the cloned 5-HT₆ and 5-HT₇ serotonin receptors. Also an allosteric potentiator of M₁ muscarinic receptors.
