Application

Dextromethorphan hydrobromide monohydrate has been used as a substrate for cytochrome P450 2D6 enzyme action, in potassium phosphate buffer for measuring P450 activity and is used in enzyme inhibition studies.

Biochem/physiol Actions

Dextromethorphan hydrobromide is an allosteric antagonist at N-methyl D- aspartate (NMDA)-controlled ion channels and antagonist at voltage-dependent channels. Dextromethorphan hydrobromide is useful in treating dry cough.

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

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
