Combining Baclofen and Oxymorphone Hydrochloride is a major interaction and should generally be avoided without close medical supervision.
Patients may experience increased sedation, dizziness, confusion, and psychomotor impairment. The most significant risk is profound respiratory depression, which can be life-threatening. Other effects include hypotension and coma.
Mechanism: Oxymorphone is an opioid analgesic that acts as a mu-opioid receptor agonist, causing central nervous system (CNS) depression. Baclofen is a gamma-aminobutyric acid (GABA) analogue that acts as a GABA-B receptor agonist, also producing CNS depressant effects. The co-administration of these two agents results in an additive depressant effect on the CNS.

Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression. The precise mechanism …
