Combining Chlorzoxazone and Tapentadol Hydrochloride is a major interaction and should generally be avoided without close medical supervision.
Patients may experience increased sedation, dizziness, confusion, and psychomotor impairment. There is an elevated risk of respiratory depression, which can be life-threatening, and profound hypotension.
Mechanism: Tapentadol is an opioid analgesic with mu-opioid receptor agonist and norepinephrine reuptake inhibition properties, leading to central nervous system (CNS) depression. Chlorzoxazone is a centrally acting muscle relaxant that also causes CNS depression. The concomitant use of these agents results in additive CNS depressant effects.
