Zencoxia-TH Tablet is a combination medication containing Etoricoxib 60 mg and Thiocolchicoside 4 mg, formulated for the management of musculoskeletal pain and inflammation associated with conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute musculoskeletal disorders. Etoricoxib, a selective COX-2 inhibitor, provides effective analgesic and anti-inflammatory effects by selectively inhibiting the cyclooxygenase-2 enzyme, thereby reducing prostaglandin synthesis responsible for pain and inflammation. Thiocolchicoside, a muscle relaxant with anti-inflammatory properties, acts by antagonizing glycine receptors and modulating muscle tone, thereby alleviating muscle spasms and associated discomfort. The combination of these agents offers synergistic benefits, addressing both inflammatory pain and muscle spasticity. Zencoxia-TH is indicated for short-term use in patients requiring relief from painful muscle conditions and inflammatory joint disorders. It is recommended to be used under medical supervision, considering contraindications such as hypersensitivity to components, active gastrointestinal ulcers, severe hepatic or renal impairment, and cardiovascular risk factors. Common adverse effects may include gastrointestinal disturbances, dizziness, and mild allergic reactions. Patients should adhere to prescribed dosages and report any unusual symptoms to their healthcare provider promptly.
