DILAUDID (hydromorphone hydrochloride), a hydrogenated ketone of morphine, is an opioid agonist.
DILAUDID INJECTION is available as a sterile, aqueous solution in clear and colorless single-dose prefilled syringes for slow intravenous, subcutaneous, or intramuscular administration. Each 1 mL of solution contains 1 mg or 2 mg of hydromorphone hydrochloride.
The chemical name of DILAUDID is 4,5α-epoxy-3-hydroxy-17-methylmorphinan-6-one hydrochloride. The molecular weight is 321.80. Its molecular formula is C17H19NO3·HCl, and it has the following chemical structure:
Hydromorphone hydrochloride is a white or almost white crystalline powder that is freely soluble in water, very slightly soluble in ethanol (96%), and practically insoluble in methylene chloride.
The inactive ingredients in DILAUDID (hydromorphone hydrochloride) include: 0.2% sodium citrate and 0.2% citric acid added as a buffer to maintain a pH between 3.5 and 5.5.
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.
