How BrandName Metaxalone 400 mg work
This medicine consists of active ingredients such as diclofenac 50 mg and metaxalone 400 mg that work together to relieve pain and muscle spasms. Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) that reduces pain, swelling, and inflammation by blocking the production of prostaglandins (pain-producing chemicals in the body). Metaxalone is a centrally acting muscle relaxant that helps reduce muscle spasm and stiffness, allowing muscles to relax and improve mobility.
