Diclofenac + Trypsin Chymotrypsin is a combination of two medicines: Diclofenac and Trypsin Chymotrypsin which relieve pain and inflammation. Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) which works by blocking the release of certain chemical messengers in the brain that are responsible for pain, fever and inflammation (redness and swelling). Trypsin Chymotrypsin is a combination of enzymes which break down proteins into smaller fragments, thereby making them available for absorption into the blood. Once absorbed, they increase blood supply in the affected area and reduce swelling.
