Nimesulide (CAS NO.51803-78-2) was launched in Italy for the first time as Aulin and Mesulid in 1985. It has become a leading non-steroidal anti-inflammatory drug in over 50 countries worldwide. In 2002 nimesulide benefit/risk profile was reviewed by the EMEA following decision to temporarily suspend the drug from the market in March 2002.
Due to concerns about the risk of hepatotoxicity, nimesulide has been withdrawn from market in many countries.
Nimesulide (CAS NO.51803-78-2) is a relatively COX-2 selective, non-steroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic properties. Its approved indications are the treatment of acute pain, the symptomatic treatment of osteoarthritis and primary dysmenorrhoea in adolescents and adults above 12 years old.
