A highly selective cyclooxygenase 2 inhibitor, it was briefly used for the treatment of osteoarthritis, but was withdrawn due to concersns of hepatotoxicity. It has a role as a cyclooxygenase 2 inhibitor and a non-steroidal anti-inflammatory drug. It is an organofluorine compound, an organochlorine compound, an amino acid, a secondary amino compound and a monocarboxylic acid."}]
