Dextromethorphan is used widely in vivo to phenotype the polymorphically expressed cytochrome P450 (CYP) 2D6. Dextromethorphan is N-demethylated in vitro to 3-methoxymorphinan by human CYP3A4/5. We examined whether the dextromethorphan/3-methoxymorphinan urinary metabolic ratio (MR) could be used as an in

Dextromethorphan has been used as an antitussive for more than 40 years and is considered a drug with a good margin of safety. The aim of the study was to evaluate whether dextromethorphan and its metabolites--3-methoxymorphinan and dextrorphan--had local anaesthetic

Cytochromes mediating the biotransformation of dextromethorphan to dextrorphan and 3-methoxymorphinan, its principal metabolites in man, have been studied by use of liver microsomes and microsomes containing individual cytochromes expressed by cDNA-transfected human lymphoblastoid cells. In-vitro formation of dextrorphan from dextromethorphan

Biochemical pharmacology, 45(4), 833-839 (1993-02-24)
The O-demethylation of dextromethorphan (DM) to dextrorphan (DR) is catalysed by the polymorphic CYP2D6 (cytochrome P4502D6) isozyme in man. DM is commonly used as a probe for phenotyping subjects as either poor or extensive metabolizers for the debrisoquine/sparteine oxidative polymorphism

Biopharmaceutics & drug disposition, 24(9), 367-373 (2003-12-23)
Dextromethorphan is used widely in vivo to phenotype the polymorphically expressed cytochrome P450 (CYP) 2D6. Also dextromethorphan is N-demethylated in vivo to 3-methoxymorphinan by human CYP3A4/5. The metabolic ratio (MR) of dextromethorphan/3-methoxymorphinan in plasma, saliva and urinary were examined as
