Hi all. Do any of you know about either of these? My vet recommended I let my horse participate in an FDA drug trial for "Tildren." He has a 'softening' of the navicular bone. No limping. Tildren is a drug which helps in bone reabsorbtion and remaking of bone and has been used in Europe for a number of years. However, I can find no information online about it other than a few veterinary threads which reference the potential bad side affects. ( Colic and heart attacks ) It is administered in a 4 hour IV drip which seems like a horrible thing to put my horse thru. When I was researching Tildren I also found a product called Gallium Nitrate. It is, apparently, a mineral that used to be plentiful in the soil and is now primarily leached out. Gallium Nitrate is used in people to help in bone reabsorbion and remaking of bone and has been used in some horses over the last 10 years. However, as much as I search forums and blogs, I have fiound 1 person who used Gallium Nitrate and had good results and no one who used Gallium and had bad results. So. My questions are: Does anyone have any experience or information on either of these products? Has anyone used Gallium? Thanks, thanks, thanks.
