Nucoxia MR Tablet contains a combination of Etoricoxib 60 mg and Thiocolchicoside 4 mg, formulated for the management of musculoskeletal pain and inflammatory conditions. Etoricoxib is a selective COX-2 inhibitor that provides effective analgesic and anti-inflammatory effects by reducing the synthesis of prostaglandins involved in pain and inflammation, thereby minimizing gastrointestinal side effects commonly associated with non-selective NSAIDs. Thiocolchicoside is a muscle relaxant with anti-inflammatory properties that acts by selectively binding to GABA and glycine receptors, resulting in the relief of muscle spasms and stiffness. The combination of these active ingredients in Nucoxia MR Tablet offers synergistic benefits, making it suitable for treating acute and chronic musculoskeletal disorders such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and low back pain with muscle spasm. It is recommended to be used under medical supervision, considering contraindications such as hypersensitivity to either component, active gastrointestinal bleeding, severe hepatic or renal impairment, and cardiovascular risk factors. Common adverse effects may include gastrointestinal discomfort, dizziness, or mild allergic reactions. Patients should adhere to prescribed dosages and consult healthcare professionals before use, especially if pregnant, breastfeeding, or on concomitant medications to avoid potential drug interactions.
