Combining Metaxalone and Oxymorphone Hydrochloride is a major interaction and should generally be avoided without close medical supervision.
Patients may experience profound sedation, respiratory depression, hypotension, coma, and even death. Impaired psychomotor function, dizziness, and confusion are also common, increasing the risk of falls and accidents.
Mechanism: Oxymorphone, an opioid agonist, produces central nervous system (CNS) depression by binding to mu-opioid receptors. Metaxalone, a centrally acting skeletal muscle relaxant, also causes generalized CNS depression. The concurrent use of these agents results in an additive depressant effect on the CNS.

Metaxalone
Metaxalone’s mechanism of action has not been fully characterized, but may be related to its sedative properties. Metaxalone has no direct action on the contractile mechanism of striated muscle, the motor end plate, or the nerve fiber.

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 …
