Diclofenac Sodium 50mg. + Paracetamol 325mg. + Chlorzoxazone 250mg. is a combination medication used to relieve pain and muscle spasms associated with musculoskeletal conditions. Diclofenac sodium is a non-steroidal anti-inflammatory drug (NSAID) that reduces inflammation, pain, and swelling by inhibiting the production of prostaglandins, chemicals in the body that promote inflammation. Paracetamol (acetaminophen) provides additional pain relief and reduces fever. Chlorzoxazone is a muscle relaxant that works by relaxing muscles and reducing muscle spasms. This combination is particularly effective for conditions such as muscle pain, strains, sprains, or other musculoskeletal disorders where pain, inflammation, and muscle spasms occur together.
