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.

Clozapine is restricted to use in patients with treatment-refractory schizophrenia due to the risk of a serious drop in absolute neutrophil granulocyte count (ANC). The formation of reactive, unstable metabolites (adducts) has been suggested as a mechanism of clozapine-induced granulocyte
