Hn TH4 Tablet is a combination medication containing Aceclofenac 100 mg and Thiocolchicoside 4 mg, formulated for the management of pain and inflammation associated with musculoskeletal disorders. Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) that exerts its therapeutic effect by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), leading to a reduction in prostaglandin synthesis, thereby alleviating pain and inflammation. Thiocolchicoside is a muscle relaxant with anti-inflammatory and analgesic properties, acting as a selective antagonist of GABA and glycine receptors, which helps in relieving muscle spasms and stiffness. The combination of these two agents provides synergistic benefits in conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute musculoskeletal injuries. Hn TH4 Tablet is indicated for short-term use to improve patient mobility and reduce discomfort associated with inflammatory and spastic conditions. It should be used under medical supervision, considering contraindications such as hypersensitivity to NSAIDs, active gastrointestinal ulcers, and certain cardiovascular or hepatic conditions. Common adverse effects may include gastrointestinal disturbances, dizziness, and allergic reactions. Patients are advised to follow prescribed dosages and report any unusual symptoms promptly to their healthcare provider.
