Mavacoxib
Mavacoxib (trade name Trocoxil) is a veterinary drug used to treat pain and inflammation in dogs with degenerative joint

Mavacoxib, along with other COX-2 selective inhibitors, celecoxib, valdecoxib, and parecoxib, were discovered by a team at the Searle division of Monsanto led by John Talley.
