Morphinan-6-one,4,5-epoxy-3-hydroxy-17-methyl-, hydrochloride (1:1), (5a)- (71-68-1)

 Dilaudid (71-68-1) is a potent centrally-acting analgesic drug of the opioid class. It is a derivative of morphine, specifically a hydrogenated ketone thereof and therefore a semi-synthetic drug. It is both medically an opiate analgesic and legally a narcotic. It should not be confused with hydromorphinol, also known as 14-hydroxydihydromorphine and RAM-320 nor dihydromorphine (Paramorfan). While all of these are strong opioids, they are indeed different drugs. Additional confusion arises from the fact that in a handful of countries hydromorphinol is distributed under the trade name Numorphan, which is the trade name for oxymorphone in the rest of the world according to the current version of The A-Z Encyclopaedia of Alcohol & Drug Abuse and other references.It is known in various countries around the world by the trade names Hydal, Sophidone, Hydrostat Hydromorfan, Hydromorphan, Laudicon, Hymorphan, Opidol, Palladone and others (warning: the brand names are inconsistent from country to country). An extended-release version of hydromorphone called Palladone was available for a short time in the United States before being voluntarily withdrawn from the market after a July 2005 FDA advisory warned of a high overdose potential when taken with alcohol. As of March 2007 it is still available in the United Kingdom under the brand name Palladone SR, and in most other European countries. Another extended-release version called Hydromorph Contin, manufactured as controlled release capsules, continues to be produced and distributed in Canada by Purdue Pharma Inc. of Pickering, Ontario. In addition to Purdue-Frederick, manufacturers of hydromorphone products include Ethex, Knoll, Abbott, Endo, Mallinkroft, Merck, Mundipharma, and Lannacher, amongst others.
