Ireecox 90 Tablet contains Etoricoxib 90 mg, a selective cyclooxygenase-2 (COX-2) inhibitor used primarily for the management of pain and inflammation associated with osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute gouty arthritis. Etoricoxib works by selectively inhibiting the COX-2 enzyme, thereby reducing the synthesis of prostaglandins responsible for inflammation, pain, and fever, while sparing COX-1, which helps maintain gastrointestinal mucosal integrity. This selective mechanism offers an improved gastrointestinal safety profile compared to non-selective nonsteroidal anti-inflammatory drugs (NSAIDs). Ireecox 90 Tablet is indicated for short-term and long-term treatment of musculoskeletal disorders and inflammatory conditions where pain relief and anti-inflammatory effects are desired. The recommended dosage should be individualized based on the patient’s clinical condition and response, with caution advised in patients with cardiovascular risk factors, renal impairment, or hepatic dysfunction. Contraindications include hypersensitivity to Etoricoxib or other NSAIDs, active peptic ulcer disease, severe heart failure, and pregnancy. Common adverse effects may include headache, dizziness, hypertension, and gastrointestinal discomfort. Patients should be monitored regularly for any signs of adverse reactions, and use should be in accordance with current clinical guidelines to optimize therapeutic outcomes while minimizing risks.
