Onsior (Robenacoxib)

What is Onsior?
Onsior (robenacoxib) is a non-steroidal anti-inflammatory drug (NSAID) used in veterinary medicine for dogs and cats. It is commonly used for post operative pain and musculoskeletal pain such as osteoarthritis. 
Onsior works by selectively inhibiting COX-2 enzymes, which are responsible for producing inflammatory chemicals this in turn results in less side effects compared to traditional NSAIDs.
