Diazepam and Oxymorphone Hydrochloride must not be used together. This combination is classified as CONTRAINDICATED.
The concurrent use of oxymorphone and diazepam can lead to profound sedation, respiratory depression, coma, and death. Patients may experience decreased level of consciousness, hypoventilation, apnea, hypotension, and psychomotor impairment. This interaction significantly increases the risk of accidental overdose and life-threatening adverse events.
Mechanism: Oxymorphone, an opioid agonist, and diazepam, a benzodiazepine, both depress the central nervous system (CNS). Opioids primarily act on mu-opioid receptors to inhibit GABAergic interneurons, leading to disinhibition of dopamine neurons and respiratory depression. Benzodiazepines enhance the effect of the inhibitory neurotransmitter GABA at the GABA-A receptor, increasing chloride ion influx and hyperpolarizing neurons. The synergistic CNS depressant effects of these two drug classes significantly amplify respiratory depression, sedation, and psychomotor impairment.

The principal therapeutic action of oxymorphone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxymorphone. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression. The precise mechanism …
