Boehringer Ingelheim Announces the Launch of Centragard™ (eprinomectin and praziquantel transdermal solution), Innovative Internal Parasite Protection For Cats

Merial, now part of Boehringer Ingelheim, and the maker of HEARTGARD® Plus (ivermectin/pyrantel), the leader in canine heartworm disease prevention, brings heartworm disease prevention and broad-spectrum treatment of intestinal parasites to felines, with new easy-to-use CENTRAGARD.  

DULUTH, Ga. Aug. 20, 2018 – Heartworm disease is a serious and potentially deadly threat to cats. Heartworms are difficult to diagnose in cats, and there is no approved treatment to eliminate feline heartworm infections. Today, Boehringer Ingelheim announces the launch of CENTRAGARD™ (eprinomectin and praziquantel transdermal solution), a monthly heartworm disease preventive product for cats that is applied topically. 

CENTRAGARD is also approved to treat and control three of the most common intestinal parasites of cats -- hookworms, roundworms, and tapeworms. It is the first, and only, product to protect against this spectrum of parasites in an easy-to-use transdermal formulation.  

“All it takes is one mosquito to transmit heartworms to your cat – and just a few heartworms can lead to severe signs, possibly death,” explains Zach Mills, DVM Head of U.S. Pet Veterinary Professional Services at Boehringer Ingelheim. "Now cat owners have a new option to protect their cats."

Heartworm disease is a serious and potentially fatal disease that can affect dogs, cats, and other animals. The risk of heartworms is widespread in the U.S. Heartworms are transmitted by infected mosquitoes. Mosquitoes become infected with heartworm microfilariae while taking a blood meal from an infected dog, and then can transmit the heartworms to cats. Once in the cat, heartworm larvae develop in the cat’s tissues and then migrate to the bloodstream. They reach the blood vessels of the heart and lungs in a few months. 

Even indoor cats are at risk of exposure to these parasites. According to the American Heartworm Society, 1 in 4 cats diagnosed with heartworm disease are indoor-only pets1. “Some cat owners may assume that their indoor cat will not be exposed to heartworm disease or harmful intestinal parasites. In reality, even indoor cats are at risk of exposure to these parasites,” Mills added.
