Combining Buprenorphine and Chlorzoxazone is a major interaction and should generally be avoided without close medical supervision.
Patients may experience increased sedation, dizziness, and psychomotor impairment. The most serious clinical effect is an enhanced risk of respiratory depression, which can be life-threatening. Other effects include profound somnolence, confusion, and difficulty concentrating.
Mechanism: Buprenorphine, an opioid partial agonist, exerts its primary effects through mu-opioid receptor agonism, leading to central nervous system (CNS) depression. Chlorzoxazone, a centrally acting muscle relaxant, also causes CNS depression by acting on subcortical and spinal cord levels. The co-administration of these agents results in an additive depressant effect on the CNS.
