Dextromethorphan
Posted May 19, 2008 at 06:18 AM.
Dextromethorphan (DXM or DM) is an antitussive (cough suppressant) drug found in many over-the-counter cold and cough medicines. Dextromethorphan has also found other uses in medicine, ranging from pain relief to psychological applications. Pure dextromethorphan occurs as a powder made up of white crystals, but it is generally administered via syrups, tablets, or lozenges manufactured under several different brand names and generic labels.
When taken at doses higher than are medically recommended, dextromethorphan acts as a dissociative hallucinogenic drug. It is classified neurochemically as an NMDA receptor antagonist, producing effects similar to those of the controlled substances ketamine and phencyclidine (PCP) which affords it a significant potential for abuse.
