Combining Methadone and Orphenadrine Citrate is a major interaction and should generally be avoided without close medical supervision.
Patients may experience profound sedation, respiratory depression, coma, and even death. Other clinical manifestations include dizziness, confusion, impaired psychomotor function, and hypotension. The risk is heightened in elderly patients or those with pre-existing respiratory compromise.
Mechanism: Methadone is a potent opioid agonist that produces central nervous system (CNS) depression through mu-opioid receptor activation. Orphenadrine citrate, an anticholinergic and antihistaminic agent with muscle relaxant properties, also exerts CNS depressant effects. The co-administration of these agents leads to an additive depressant effect on the CNS.
