![]() If your horse is competing in a sanctioned competition where there are drug rules, you should consult with a knowledgeable veterinarian regarding the withdrawal time for isoxsuprine.īe sure to discuss any side effects with your veterinarian immediately. Wash your hands after giving your pet this medication.ĭespite the low level of oral absorption, isoxsuprine can be found in a horse's urine for many weeks after treatment is discontinued. If you miss giving your horse a dose of isoxsuprine, give the next dose as soon as you remember or, if it is close to the next scheduled dose, return to the regular schedule. Give this medication to your horse exactly as your veterinarian prescribes. Instead, it is compounded by a specialty pharmacy. Like many other drugs in veterinary medicine, isoxsuprine is not FDA approved for use in animals and is not available from a veterinary pharmaceutical manufacturer. Its effectiveness in the broodmare has not been well evaluated. ![]() Because of its demonstrated effectiveness in humans, some veterinarians use isoxsuprine for the same purpose in broodmares. Isoxsuprine is used in human medicine to treat premature labor and prevent abortion. Nevertheless, there are many veterinarians who feel that it is helpful in selected cases. The use of oral isoxsuprine in the horse is not universally accepted because it has been shown that horses only absorb a very small amount of this drug through their digestive tracts. This drug works by relaxing the smooth muscle that surrounds small blood vessels causing "vasodilation" and potentially increasing blood flow to the hooves. In all cases, therapeutic farriery should be based on the horse’s individual case needs rather than on a standard formula.Isoxsuprine is a human drug that is sometimes used in horses to treat navicular disease or laminitis. Hooves must be able to expand when they make contact with the ground, plus roll forward efficiently (good “rollover” requires toes to be properly shortened and beveled). The feet must be carefully balanced, with all weight-bearing structures brought into play. A skilled farrier should first remedy any pre-existing problems, including underrun, contracted, or sheared heels mismatched hoof angles or a broken hoof/pastern axis. Shelley PaulsonĬorrect trimming/shoeing should be the basis of all heel-pain treatment, with any medicinal or surgical strategies considered adjuncts. Though navicular syndrome usually can’t be fully cured, proper management and treatment can reduce stress, inflammation, and pain in the affected areas, and some horses may even remain ridable. The intermittent use of NSAIDs (such as bute) may also be a part of the plan. In addition, depending on the source of your horse’s pain, your vet may propose medical therapies applied systemically or injected into the coffin joint or navicular bursa to reduce inflammation or preserve bone (at right). If your horse does develop heel pain, your vet is likely to recommend therapeutic trimming and/or shoeing (see below). These include correct and regular hoof care, proper nutrition (that prevents obesity), regular exercise plus turnout, and decent footing. To lower the risk that your horse will ever develop navicular syndrome, provide all the horsekeeping standards that are basic to excellent care. ![]() MRI and other advanced imaging techniques may be needed the more precise the diagnosis of the cause, the more precise and effective the treatment. Your vet will determine whether your horse has navicular syndrome, then try to pinpoint which disease process is at work. Watch for these symptoms and consult with your veterinarian if any appear: increased stumbling a shortened, choppy stride standing with a front foot pointed front-end tenderness on hard ground or when moving in a circle. Horses with large, heavy bodies and small hooves are at even greater risk. Heel pain can occur to any horse, but the risk is higher for Quarter Horses, Thoroughbreds, and warmbloods, especially those over the age of 7. Palmar heel pain is an alternate term, referring to the site of the nerve block (at the back and bottom of the front feet) that resolves pain for all these conditions. Navicular syndrome refers to a variety of conditions that create pain in and around the structures surrounding the navicular bone. ![]()
