Ouxia 120 Tablet contains Etoricoxib 120 mg, a selective cyclooxygenase-2 (COX-2) inhibitor used primarily for the management of pain and inflammation associated with various musculoskeletal and inflammatory conditions. Etoricoxib exerts its therapeutic effects by selectively inhibiting the COX-2 enzyme, thereby reducing the synthesis of prostaglandins involved in inflammation and pain, while sparing COX-1, which helps maintain gastrointestinal mucosal integrity. Ouxia 120 is indicated for the treatment of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute gouty arthritis, as well as for the relief of acute musculoskeletal pain and postoperative dental pain. The recommended dosage should be individualized based on the patient's condition and response to therapy, with careful consideration of contraindications and potential adverse effects. Common side effects may include gastrointestinal discomfort, headache, dizziness, and elevated blood pressure. Due to its selective mechanism, Ouxia 120 generally has a lower risk of gastrointestinal ulceration compared to non-selective NSAIDs, but caution is advised in patients with cardiovascular risk factors, renal impairment, or hepatic dysfunction. It is essential to use Ouxia 120 under medical supervision, adhering to prescribed dosages and monitoring for any signs of adverse reactions or drug interactions.
