How Eprytor-A Tablet SR works

Eprytor-A Tablet SR is a combination of two medicines: Eperisone and Aceclofenac, which relieve pain and relax the muscles. Eperisone is a muscle relaxant. It works on the centres in the brain and spinal cord to relieve muscle stiffness or spasm and to improve pain and movement of muscles. Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) that works by blocking the release of certain chemical messengers that cause pain and inflammation (redness and swelling).
