Oxalgin-DP Tablet contains Diclofenac (analgesic) and Paracetamol (fever reducer/mild analgesic), effective against painful musculoskeletal pain, joint pain, and skeletal muscle spasms. Diclofenac works by blocking the action of a chemical messenger known as cyclo-oxygenase (COX), which causes pain and swelling at the injured or damaged tissue site. On the other hand, paracetamol acts as a mild analgesic (mild pain reducer) and antipyretic (fever reducer), enhancing Diclofenac's pain relief action. It also helps relieve toothache, ear pain, backache and other musculoskeletal-related pain.
