Botox For Laminitis & Founder?

I read an interesting article in Equus magazine this morning & thought I'd share. The article was about using Botox to aid in the prevention & treatment of laminitis & founder. Botox is the trade name for a botulinum toxin. The toxin blocks muscle contractions & causes localized muscular paralysis. It's this property that makes Botox popular for reducing facial wrinkles.

A pediatric neurologist & a vet teamed up on a study of Botox use for laminitic & foundered horses. They also studied it's use as a preventative to these 2 devastating diseases. Their study consisted of 7 horses, 6 with varying degrees of laminitis & founder plus 1 horse who had a serious injury to a front leg. The premise for their study was to see if Botox injections would relax the deep digital flexor tendon so it didn't contract & pull the coffin bone into the classic, founder rotation. This would be equivalent to cutting the tendon, which has been the traditional method of treatment for rotation, barring euthanasia. The study horses were injected with Botox above the knees of each affected leg. After 2 weeks, x-rays showed that rotation in the affected hooves had stabilized. The horse who was given Botox as a preventative because of the severe injury never developed laminitis. The effects of Botox begin in a few days & peaks at 2 weeks, with about 3 months being the lasting length of 1 injection.

Botox treatments aren't cheap & depending on the severity of the laminitis & founder, multiple treatments might be needed. The article stated the cost between $1500-$2000 per leg. But when faced with laminitis & founder, there is now one more option that gives our horses a chance at life.
