Normethadone (INN, BAN; brand names Ticarda, Cophylac, Dacartil, Eucopon, Mepidon, Noramidone, Normedon, and others), also known as desmethylmethadone or phenyldimazone, is a synthetic opioid analgesic and antitussive agent.[citation needed] Normethadone is listed under the Single Convention on Narcotic Drugs 1961 and is a Schedule I Narcotic controlled substance in the United States, with a DEA ACSCN of 9635 and an annual manufacturing quota of 2 grams. It has an effective span of action for about 14 days, and is 12 to 20 times stronger than morphine. [1] The salts in use are the hydrobromide (free base conversion ratio 0.785), hydrochloride (0.890), methyliodide (0.675), oxalate (0.766), picrate (0.563), and the 2,6-ditertbutylnapthalindisulphonate (0.480).[2]
