Aceclofenac + Paracetamol + Thiocolchicoside is a combination of a muscle relaxant (Thiocolchicoside) and two pain relievers ( Aceclofenac , Paracetamol). The muscle relaxant works on the centers in the brain and spinal cord to relieve muscle stiffness or spasm and improve movement of muscles. The pain relievers work by blocking the release of certain chemical messengers in the brain that cause pain and inflammation (redness and swelling).
