Effects of Repeated Smoking and Quitting Cigarettes on Plasma Concentrations of Clozapine and Its N-Desmethyl and N-Oxide Metabolites in a Japanese Patient With Schizophrenia. [PDF]

Neuropsychopharmacol Rep
In a Japanese patient with schizophrenia, the effects of repeated smoking and quitting cigarettes on plasma concentrations of clozapine (CLZ) and its major metabolites, N‐desmethyl clozapine (NCLZ) and N‐oxide clozapine (OCLZ), were shown to be reproducible. ABSTRACT Clozapine (CLZ) is used for treatment‐resistant schizophrenia.
