Rimadyl keeps changing its name. It was called norocarp for a while but this was changed (I think) because its name was very similar to an antibiotic called noroclav (synulox) and mistakes in administration were recorded.
Its now called carprofen.
Found this;
Carprodyl® is a non-steroidal anti-inflammatory drug (NSAID) for the safe treatment of inflammation and pain relief in chronic diseases of the musculoskeletal system (canine arthritis, osteoarthrosis, orthopedic) and soft tissue surgery in dogs. Carprodyl is offered as chewable, brown oval scored liver-flavored tablets, containing 25 or 100 mg of carprofen.
Hope that helps!
