One-TH Tablet is a combination medication containing Aceclofenac 100 mg and Thiocolchicoside 4 mg, formulated for the management of musculoskeletal pain and inflammation. Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) that exerts its effect by inhibiting cyclooxygenase enzymes, thereby reducing the synthesis of prostaglandins responsible for pain and inflammation. Thiocolchicoside is a muscle relaxant with anti-inflammatory properties, acting as a selective antagonist of GABA and glycine receptors, which helps in relieving muscle spasms and associated discomfort. The synergistic action of these two active ingredients makes One-TH Tablet effective in treating conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute musculoskeletal disorders including strains and sprains. It is indicated for patients requiring both anti-inflammatory and muscle relaxant therapy to improve mobility and reduce pain. One-TH Tablet should be used under medical supervision, considering contraindications such as hypersensitivity to NSAIDs, peptic ulcer disease, and severe hepatic or renal impairment. Common adverse effects may include gastrointestinal disturbances, dizziness, and allergic reactions. Caution is advised in patients with cardiovascular risk factors. The dosage and duration of treatment should be individualized based on clinical response and tolerability.
