Gastrointestinal parasites should be periodical controlled in horses to maintain their productive performance and adequate health. The objective of the research was to know the effect and safety of closantel combined with fenbendazole on the eggs of gastrointestinal parasites in horses. The drug combination was administered to 102 horses of different breed, age, sex and body weight at a dose of 10 mg per kg each drug. Physiological constants were measured before and 90 minutes after the drug was administered. Additionally, a sample was collected directly from the rectum of the horses during the physical examination to determine the presence and quantity of eggs. In positive animals, samples were taken 15, 30 y 45 days after treatment to determine the time that the administrated drugs can protect the horses. In the results, 53 horses were positive for parasites, the drug showed efficacy of 99% at 15 days after treatment and 89.79 at 45 days, in the 102 treated horses there was no effect on the physiological variables evaluated. It is concluded that the combination of closantel with fenbendazole at 10 mg per kg of body weight has efficacy of 99% post application and is safe for horses.
