Combining Orphenadrine Citrate and Oxymorphone Hydrochloride is a major interaction and should generally be avoided without close medical supervision.
Patients may experience profound sedation, respiratory depression, hypotension, and psychomotor impairment. This can lead to increased risk of falls, accidental injury, and potentially life-threatening respiratory compromise, especially in opioid-naive individuals or those with underlying respiratory conditions.
Mechanism: Oxymorphone is an opioid agonist that produces central nervous system (CNS) depression through its action on mu-opioid receptors. Orphenadrine is an anticholinergic muscle relaxant with significant CNS depressant and sedative properties. The co-administration of these two agents results in an additive depressant effect on the CNS.
