Efficacy
Previcox is an NSAID used to treat postoperative pain and inflammation and manage pain and inflammation in dogs with osteoarthritis. It works by inhibiting the production of chemicals known as prostaglandins and features firocoxib as its active ingredient.
The prescribing information for Previcox provides details of several field studies conducted to determine the safety and efficacy of the medication. These include:
In a study of 249 dogs, pets were assessed for lameness, pain on manipulation, range of motion, joint swelling, and overall improvement. At the end of the study, 87% of owners rated dogs treated with Previcox as improved, while veterinarians rated 88% of Previcox-treated dogs as improved.
In a separate study, 258 dogs received Previcox or a control following soft-tissue therapy. Dogs treated with Previcox had a significantly lower need for rescue medication than those pets that needed the control.
In a study of postoperative pain and inflammation in 226 dogs following orthopedic surgery, dogs who received Previcox had a significantly lower need for rescue medication than those dogs who received the control.
A study into the long-term efficacy and safety of firocoxib, the active ingredient in Previcox, saw dogs treated with 5mg/kg firocoxib once a day for 52 weeks. Results showed that 82% of the dogs had improved by day 15, 84% by day 90, and 96% of the dogs who completed the trial had improved by day 360. However, 5.1% of dogs enrolled in the study were later withdrawn due to gastrointestinal side effects.
