 Dextromethorphan - Wikipedia, the free encyclopedia
Dextromethorphan (DM or DXM) is an antitussive drug that is found in many over-the-counter cold and cough preparations, usually in the form of dextromethorphan hydrobromide.
The advantage of dextromethorphan preparations over those containing codeine (now prescription only in the United States) was the lack of physical addiction potential and sedative side-effects, although as with most cough supressants, studies show that its effectiveness is highly debatable.
Hours after dextromethorphan therapy, (in humans) the metabolites (+)-3-hydroxy-N-methylmorphinan, (+)-3-morphinan, and traces of the unchanged drug are detectable in the urine.

 The Ultimate Dextromethorphan - American History Information Guide and Reference
Dextromethorphan is the dextrorotary-enantiomer of the opioid-receptor agonist levomethorphan.
Dextromethorphan is predominantly metabolized by the liver, by the hepatic cytochrome P450 enzyme known as CYP2D6.
The advantages of dextromethorphan over codeine are the absence of constipation and physical dependence; it is also less sedative, and has little to no psychological effect in the doses used medically (typically no more than 30 mg, or slightly more, spread over several hours; 10-15 mg is a common dose in cough syrups).

 Review of Dextromethorphan Efficacy, Safety, Abuse Potential, and Investigational Uses
Dextromethorphan is a substrate for a variety of other Cytochrome P450 isoenzymes, such as CYP2B6 (minor), 2C8/9 (minor), 2C19 (minor), 2D6 (major), 2E1 (minor), 3A4 (minor).
In 1995, it was reported that dextromethorphan and dextrorphan concentrations after ingesting dextromethorphan varied between individuals due to the genetic polymorphisms of the CYP2D6 enzyme.
Clinical trials confirm that dextromethorphan does not produce physical addiction, lose effectiveness through increased tolerance, or cause withdrawal, even in high experimental doses, but this was over a relatively short period of time.

 Clinical Trial: Studies of Dextromethorphan and Topiramate to Treat Oral and Facial Pain
Dextromethorphan, a commonly used cough suppressant, and topiramate, an anti-seizure medicine, block certain receptors on brain and spinal nerve cells that may cause the cells to produce electrical discharges and pain.
Thus, the purpose of this study is to evaluate the efficacy and safety of topiramate (TPM) or high-dose dextromethorphan (DM) versus placebo in the treatment of pain in patients with trigeminal neuralgia (TN) and other orofacial neuropathic pain syndromes.
We propose two 6 month studies respectively evaluating dextromethorphan (60 patients; at least 20 with TN, 20 with definite trigeminal nerve pathology and 20 with likely trigeminal nerve pathology) and topiramate (40 patients; at least 20 with TN, 20 with definite trigeminal nerve pathology).

Consuming large amounts of dextromethorphan from combination products that include acetaminophen, pseudoephedrine, or antihistamines is more dangerous because of the ancillary toxic effects of these other compounds.
Repackaging of bulk powdered dextromethorphan for resale as dextromethorphan or as counterfeit PCP or Ecstasy may be a criminal act subject to the jurisdiction of either the FDA (misbranding) or the DEA (counterfeit controlled substance).
