Overview
11 DESCRIPTION Hydromorphone hydrochloride, a hydrogenated ketone of morphine, is an opioid agonist. Hydromorphone hydrochloride tablets are supplied in 2 mg, 4 mg, and 8 mg tablets for oral administration. The tablet strengths describe the amount of hydromorphone hydrochloride in each tablet. The chemical name is 4,5α-epoxy-3-hydroxy-17-methylmorphinan-6-one hydrochloride.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Hydromorphone is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of hydromorphone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with morphine. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression. The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug. 12.

Dosage
2 DOSAGE AND ADMINISTRATION Hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. ( 2.1 ) Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals. Reserve titration to higher doses of hydromorphone hydrochloride for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the...
