Combining Fentanyl and Orphenadrine Citrate is a major interaction and should generally be avoided without close medical supervision.
Patients may experience severe respiratory depression, including hypoventilation and apnea, profound sedation, somnolence, and decreased level of consciousness. Other potential effects include dizziness, impaired psychomotor function, and increased risk of falls. In severe cases, this can lead to coma and death.
Mechanism: Both fentanyl, an opioid analgesic, and orphenadrine citrate, a skeletal muscle relaxant with anticholinergic and antihistaminic properties, exert central nervous system (CNS) depressant effects. The co-administration leads to an additive pharmacological effect on GABAergic and other inhibitory neurotransmitter systems, significantly enhancing CNS depression. This synergistic action increases the risk of profound respiratory depression and sedation.
