Hydromorphone, a more common synonym for dihydromorphinone, commonly a hydrochloride (brand names Palladone, Dilaudid, and numerous others) is a very potent centrally acting analgesic drug of the opioid class. It is a derivative of morphine, to be specific, a hydrogenated ketone thereof and, therefore, a semi-synthetic drug. It is, in medical terms, an opioid analgesic and, in legal terms, a narcotic. It is commonly used in the hospital setting, mostly intravenously (IV), due to the fact that the bioavailability oral (Mouth), rectal (Anus), or intranasal, aka "Snorting" (Nose) is very low.

Hydromorphone is used in medicine as an alternative to morphine for analgesia, and as a second- or third-line narcotic antitussive (cough suppressant) for cases of dry, painful, paroxysmal coughing resulting from continuing bronchial irritation after influenza and other ailments, inhalation of fungus, and other causes. In general, it is considered the strongest of the antitussive drugs, and was developed shortly after diacetylmorphine (heroin) was removed from clinical use for this purpose in most of the world and banned outright in many countries. The effectiveness of hydrocodone as an antitussive may be partly due to it being partially converted to hydromorphone in the liver.
