GREENFIELD, Ind., Aug. 15, 2024 /PRNewswire/ -- Parasites & Vectors, a leading peer-reviewed journal focused on parasites and vector-borne pathogens published the results of a head-to-head study demonstrating that Credelio, a prescription flea and tick protection product from Elanco Animal Health, has the fastest initial speed of tick kill in just 12 hours and sustains that advantage throughout the dosing interval.^1,2,3 According to the Centers for Disease Control (CDC), during 2019 – 2022, state and local health departments reported more than 45,000 human cases of tickborne disease to CDC.⁴ The Companion Animal Parasite Council (CAPC) recommends using products on pets that kill and/or repel ticks before pathogens are transmitted.⁵

The 2023 head-to-head study compared three popular prescription flea and tick treatment products for dogs, Credelio (lotilaner), Simparica TRIO (sarolaner, moxidectin, pyrantel), and NexGard (afoxolaner), tracking the comparative data for the relative speeds of kill of Amblyomma americanum (lone star tick) – an aggressive and expanding tick found in the United States that is one of the hardest to kill. Not only is this tick hard to kill, but it can also transmit dangerous disease-causing pathogens to pets and people. The CDC recently provided in-depth tick surveillance information regarding the aggressive nature of the lone star tick that can bite humans and transmit bacterial and viral pathogens, as well as cause alpha-gal syndrome (red meat allergy).⁶

"The results of this head-to-head study establishes Credelio as the front runner in speed of tick kill in prescription flea and tick treatment products for dogs.¹ This is important because the longer a tick is attached, the greater the risk of pathogen transmission," said Dr. Kathryn Reif, Bailey-Goodwin Endowed Associate Professor in Parasitology at Auburn University. "These pathogens can cause serious diseases, such as Rocky Mountain Spotted Fever and ehrlichiosis, so it is critical that veterinarians talk with pet owners about year-round parasite protection. Credelio's rapid and sustained speed of tick kill helps protect pets against pathogen-carrying ticks which can result in dangerous diseases."¹

The study included dogs that were randomly allocated to one of four treatment groups: Credelio, Simparica TRIO, NexGard or untreated control.

Live tick counts were performed on dogs by blinded investigators during regular intervals.¹
The study results found that by all 12-hour evaluation intervals, only the Credelio group significantly reduced lone star ticks as compared to the untreated control group.
The study observed that the Simparica TRIO and NexGard groups were not significantly different from the untreated control group by any of the 12-hour evaluation intervals.
The study also showed that Credelio significantly reduced ticks at all 12- and 24-hour evaluation time points and only Credelio provides a rapid speed of kill throughout the entire month-long treatment period.^1,2,3
Of the evaluated products, only Credelio killed ticks as fast at the end of the month as at the beginning of the month.

"This study sets Credelio apart from competitors as it maintains a rapid speed of tick kill throughout the entire monthly dosing period," said David Gosche, DVM, Elanco Sr. Director of Technical Marketing.^1,2,3 "This product maintains consistent levels of efficacy in tick kill throughout the month, outperforming the competitors tested." ^1,2,3
