Whoa! Do You Know If Your Product Adds Up?

Competing with your horse is a team effort. You give 100% percent. You want your horse to give 100%. That’s what it takes to win. But what if the equine health care product you choose is only giving 27%?1

Unfortunately, studies show that might be the case. Especially when it comes to products claiming to treat and/or prevent equine stomach ulcers, a condition affecting two out of three non-racing competitive horses.2

Horse owners need to be wary when making purchases of certain equine ulcer care product; studies and tests conducted by Scott Stanley, PhD, University of California, Davis, and by the U.S. Food & Drug Administration (FDA) have confirmed that not all products are created equal.1,3,4 And just because the product’s label contains a statement doesn’t necessarily make it so.

“Horse owners should be concerned that they aren’t always getting what they are paying for,” said Megan Green, DVM, manager, large animal veterinary services, Merial. “But this has been an ongoing problem. Some manufacturers have been making claims that simply aren’t true.”

The Studies

In studies of products claiming to treat or prevent equine stomach ulcers, some products were found to have inconsistent and varying amounts of the active ingredient used to treat or prevent ulcers--omeprazole. The studies show a wide range of omeprazole found in four different “equine ulcer” products, from as little as 27% to as much as 126%.

Ultimately, the FDA issued warning letters to the manufacturers of GastroMax 3 and Gastrotec, along with multiple other manufacturers (see complete list in the news release “FDA Issues Warning Letters for Unapproved Omeprazole Drugs Marketed for Use in Horses,” found here:
http://www.fda.gov/animalveterinary/newsevents/cvmupdates/ucm422694.htm.)

The FDA issued these warnings because the manufacturers were marketing their unapproved animal drugs “for use in the mitigation, treatment, or prevention of disease in animals.” Unapproved drugs have not been tested by the agency for safety or effectiveness.

“The wide variation of active ingredient found in these products by Dr. Stanley and the FDA really isn’t a surprise,” said Green. “Omeprazole is highly unstable, which is why it’s so important it is manufactured under the good manufacturing practices established by the FDA.”

Besides the stability challenge inherent with omeprazole, its ability to travel through a horse’s highly acidic stomach is also a concern with unproven and unapproved drugs. “For omeprazole to work, it has to travel through the horse’s stomach, which requires a special formulation,” Green added.

That special formulation is found in the only proven and FDA-approved products for equine stomach ulcers, which are ULCERGARD (omeprazole) for prevention and GASTROGARD (omeprazole) for treatment.9,10 These products are manufactured following stringent FDA guidelines, ensuring quality and efficacy.

What to Do

1. Work with a Veterinarian

A horse owner should always consult with a veterinarian before using equine health care products, advised Green. “Veterinarians have the most information and experience with equine health care, whether it be for treatment or preventive care. In most cases, they will also be familiar with the particular horse in question and can make educated health care recommendations.”

2. Check the Labels

The FDA approval process ensures a drug is safe, effective and has accurate, comprehensive labeling. In addition, following initial FDA approval, the FDA continually monitors the drug. All-FDA approved drugs for use in animals have a New Animal Drug Application (NADA) number. The six-digit NADA number and the statement “Approved by the FDA” are usually found on the drug’s label.

Unfortunately, in spite of the warning letters issued by the FDA, some illegally marketed products remain available, so horse owners should be vigilant about checking the labels to ensure they are getting products that have been proven to contain the appropriate amount of omeprazole and proven to work.

3. Get Educated

With all the products available to horse owners, knowing what is safe and effective is critical. One resource is the website www.equinedrugfacts.com, which helps explain the different types of products on the market and the FDA approval process.

“Horse owners have a significant investment in their horses and deserve to get what they are paying for,” said Green. “Working with a veterinarian, checking labels and becoming educated will help them make good health care decisions.”

Important Safety Information
