Feeding horses treated with omeprazole a well-balanced concentrate ration can ensure they receive enough calcium to make up for any deficiencies the ulcer medication could potentially cause. Researchers have found that horses treated for gastric ulcers could be getting less calcium into the bloodstream than they would normally. Depending on the calcium source, horses treated with omeprazole (such as GastroGard, the FDA-approved medications for the treatment and prevention of equine gastric ulcers) could be digesting 15-20% less calcium than when they’re not on omeprazole.
Over prolonged treatment periods, this could lead to deficiencies if the horse isn’t consuming adequate amounts of calcium, said Joe Pagan, PhD, founder of Kentucky Equine Research (KER), in Versailles...
