Pentosan isn’t FDA approved in the US I thought? Pentaussie is FDA approved as a surgical lavage but it is not the same drug as Pentosan because of the added acetyl d glucosamine. Your vet may be misinformed?[/QUOTE]
You are correct. Pentosan isn’t FDA approved for equine use in the US. PentAussie is approved and it can be written (off label I believe) as an IM or IV injection (can’t remember which one). However, it is NOT the same as Pentosan. It contains Pentosan (at 125mg/ml) and N-Acetyl Glucosamine together. The Nature Vet (Ceva) Pentosan is at 250mg/ml, so a much higher concentration, which is probably why it seems to be much more effective than the PentAussie.
