Combining Baclofen and Oxycodone is a major interaction and should generally be avoided without close medical supervision.
This interaction can manifest as profound sedation, respiratory depression, hypotension, and psychomotor impairment. Patients may experience dizziness, confusion, decreased level of consciousness, and impaired coordination, increasing the risk of falls and accidents.
Mechanism: Oxycodone, an opioid analgesic, exerts its effects primarily through mu-opioid receptor agonism, leading to central nervous system (CNS) depression. Baclofen, a skeletal muscle relaxant, acts as a GABA-B receptor agonist, also causing CNS depression. The co-administration of these agents results in an additive depressant effect on the CNS.

Oxycodone
Oxycodone is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxycodone. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression. The precise mechanism of the…

Baclofen
INDICATIONS AND USAGE Baclofen injection (intrathecal) is indicated for use in the management of severe spasticity. Patients should first respond to a screening dose of intrathecal baclofen prior to consideration for long term infusion via an implantable pump. For spasticity of spinal cord origin, chronic infusion of baclofen injection (intrathecal) via an implantable pump should be reserved for patients unresponsive to oral baclofen therapy, or those who experience intolerable CNS side effects at effective doses. Patients with spasticity due to traumatic brain injury should wait at least one …
