We recently put our aging lab onto Adequan injections (the company link is very equine-focused, but they have a canine formulation as well) to treat her arthritis, as the NSAIDS were raising her liver enzymes. We had heard about Adequan from a friend whose dog was on it—it basically extended the dog’s life (and useful, pain-free life) by two years. Many of the online testimonials point to it being a miracle drug, essentially causing the lame to walk and run again.
Why has this not been put into use for humans?
It seems obvious that it somehow didn’t pass FDA approval for humans, but I haven’t seen anything online as to why. (Most of what’s online is horse owners wondering why people can’t take it and steroid-using bodybuilders anonymously sharing stories of how they injected themselves with Canadian-purchased horse meds after some joint injury.)
Why no version for humans? Were there crazy reactions/side-effects? Would refining it for human use (it’s made from bovine tracheal tissue, apparently) take an unprofitable number of steps for the manufacturer? Seeing as how our population keeps aging, and how every drug company is eager to put anything new into the market, I can’t believe it wouldn’t sell like gangbusters if it worked even a fraction as well as it works in dogs and horses.
