Lycefenac TH 4 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 conditions. Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) that exerts its therapeutic effect by inhibiting cyclooxygenase enzymes, thereby reducing the synthesis of prostaglandins responsible for pain and inflammation. Thiocolchicoside is a muscle relaxant with anti-inflammatory and analgesic properties, acting on glycine and GABA receptors to alleviate muscle spasms and stiffness. The synergistic action of these two active ingredients makes Lycefenac TH 4 Tablet particularly useful in managing conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute musculoskeletal disorders. It is indicated for patients experiencing moderate to severe pain accompanied by muscle spasms. The medication should be used under medical supervision, considering contraindications such as hypersensitivity to NSAIDs, active gastrointestinal ulcers, or severe hepatic or renal impairment. Common adverse effects may include gastrointestinal discomfort, dizziness, or allergic reactions. Lycefenac TH 4 Tablet offers a balanced approach to pain management by addressing both inflammatory and muscular components, improving patient mobility and quality of life.
