Hifenac TH Tablet is a combination medication containing Aceclofenac 100 mg and Thiocolchicoside 4 mg, formulated to provide effective relief from pain and inflammation associated with musculoskeletal disorders. Aceclofenac, a nonsteroidal anti-inflammatory drug (NSAID), exerts its therapeutic effect by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), thereby reducing the synthesis of prostaglandins responsible for inflammation, pain, and swelling. Thiocolchicoside is a muscle relaxant with anti-inflammatory properties that acts as a selective antagonist of GABA and glycine receptors, helping to alleviate muscle spasms and stiffness. The combined action of these two agents makes Hifenac TH particularly useful in managing conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute musculoskeletal injuries including strains, sprains, and back pain. It is generally prescribed to reduce pain, improve mobility, and enhance patient comfort. Hifenac TH should be used under medical supervision, considering contraindications such as hypersensitivity to NSAIDs, peptic ulcers, and certain cardiovascular conditions. Common adverse effects may include gastrointestinal discomfort, nausea, dizziness, and allergic reactions. Patients are advised to follow the prescribed dosage and report any unusual symptoms to their healthcare provider promptly.
