Determination of dextromethorphan hydrobromide by high-performance liquid chromatography using ion-pair formation. 1980

E J Kubiak, and J W Munson

The chromatographic retention behavior of dextromethorphan hydrobromide on an octadecylsilane column was investigated as a function of the pairing ion and the mobile phase composition. Dramatic increases in the capacity factor were observed with pairing ions containing more than eight carbons and with decreasing organic modifier (acetonitrile) concentration. Several pharmaceutically important amines exhibited similar behavior with respect to acetonitrile concentration. An analytical method was developed for dextromethorphan hydrobromide bulk drug and syrups and was applied to commercial preparations.

D003915	Dextromethorphan	Methyl analog of DEXTRORPHAN that shows high affinity binding to several regions of the brain, including the medullary cough center. This compound is an NMDA receptor antagonist (RECEPTORS, N-METHYL-D-ASPARTATE) and acts as a non-competitive channel blocker. It is one of the widely used ANTITUSSIVES, and is also used to study the involvement of glutamate receptors in neurotoxicity.	d-Methorphan,Delsym,Dextromethorphan Hydrobromide,Dextromethorphan Hydrobromide, (+-)-Isomer,Dextromethorphan Hydrobromide, Monohydrate,Dextromethorphan Hydrochloride,Dextromethorphan, (+-)-Isomer,Racemethorphan,Hydrobromide, Dextromethorphan,Hydrochloride, Dextromethorphan
