The polymorphism of dextromethorphan (CAS 125-71-3) metabolism is dependent on hepatic cytochrom P4502D6 (CYP2D6) activity. The relationship between the CYP2D6 genotype and the dextromethorphan phenotype was studied in 83 healthy unrelated subjects. Genotype was determined by allele-specific polymerase chain reaction

There is increasing evidence that sigma ligands and dextromethorphan (DM) bind to at least one common high-affinity site. DM and other antitussives do not produce psychotomimetic effects. This suggested that sigma ligands may produce their characteristic effects through another site
