Laminitis. Second only to colic as the number one killer of horses, this one word diagnosis strikes fear into the hearts of horse lovers of all breeds. In addition to the unpredictable nature of the disease, laminitis often progresses quickly making rapid diagnosis and treatment essential to the horse’s survival and future quality of life.
Finally, after decades of research, science is getting closer to putting a stop to this killer with the first injectable drug treatment for acute and active chronic laminitis, Laminil. We had the chance to speak with Charles Owen, the Operating Manager of Willowcroft Pharmacy LLC, to find out more about this revolutionary treatment.
“It has been in clinical testing under FDA supervision for six years,” Owen says. “The product has been in the works for ten years, and the theory behind Laminil took 17 years to develop. It is a mast cell stabilizer that inhibits inflammatory responses from being released from the mast cells. The inflammatory response is the activator of laminitis.”
“It is the first drug to halt the inflammatory response and the laminitis cascade. Understanding the proper sequence of the laminitis cascade is vital to understanding how to treat laminitis. That is why the theory took 17 years to develop.”
By its simplest definition, laminitis is inflammation of the hoof. Although there are many causes of laminitis, the end result is often the same, the destruction of the sensitive laminae that secure the coffin bone to the hoof wall. Because Laminil is a mast cell stabilizer, it inhibits the inflammatory response from being released in excess amounts. This helps to break or stop the laminitis cascade so the affected horse is able to recover.

During the course of clinical trials, “Laminil has been successful in stopping laminitis in 80 percent of horses treated so far. The drug has been administered to more than 60 horses and 120 hooves with no adverse effects. It has shown efficacy with all types of laminitis such as insulin resistance, equine metabolic syndrome, grain overload, grass founder, trauma and weight-bearing laminitis.” (Laminil.us).
Interestingly enough, the active ingredient in Laminil is already FDA approved for use in humans. For the past six years, Laminil has been undergoing clinical testing under FDA supervision. Currently, the drug is being tested in top veterinary facilities such as Rood and Riddle Equine Hospital in Kentucky and Dubai Equine Hospital overseas.
Because clinical testing is still underway, more laminitis cases are needed for treatment. To see if your horse might qualify for participation in a clinical trial, you can visit http://www.laminil.us. Veterinarians interested in treating laminitic horses with the drug should view the “For Veterinarians” tab on the website to download inclusion forms and pharmacological details.
“Laminil is administered via retrograde venous therapy, or distal limb perfusion,” Owen says. “Laminil is injected into the digital vein at the fetlock joint, and a tourniquet is placed above it causing Laminil to back flow into the artery, which carries Laminil to the laminae of the foot, or target source of laminitis.”
“It is the first drug to halt the inflammatory response and the laminitis cascade. No other treatment has that capability.”
