You never know when your pet might be impacted by fleas, ticks and other parasites. To ensure ample protection, use the Credelio Quattro Flea and Tick Flavored Chewable Tablet for Dogs and Puppies. With a palatable beef flavor and yummy chew form, you can easily feed your canine these dog flea and tick chews. The 4 powerful ingredients, including Lotilaner, work to control and treat a variety of parasite types and eliminate ticks twice as fast. Use the flea and tick chews for dogs to protect against roundworms, hookworms and tapeworms, as well as heartworm disease, ticks and fleas.How it Works
Credelio Quattro contains four active pharmaceutical ingredients, lotilaner, moxidectin, praziquantel, and pyrantel (as pamoate salt). Lotilaner is an ectoparasiticide belonging to the isoxazoline group. Lotilaner inhibits insect and acarine gamma-aminobutyric acid (GABA)-gated chloride channels. This inhibition blocks the transfer of chloride ions across cell membranes, which results in uncontrolled neuromuscular activity leading to death of insects and acarines. The selective toxicity of lotilaner between insects and acarines and mammals may be inferred by the differential sensitivity of the insects and acarines' GABA receptors versus mammalian GABA receptors. Moxidectin is an endectocide in the macrocyclic lactone class. Moxidectin acts by interfering with the chloride channel-mediated neurotransmission in the parasite. This results in paralysis and death of the parasite. Praziquantel's mode of action is not precisely known, but treated tapeworms undergo muscular paralysis accompanied by a rapid influx of calcium ions and the disruption of the tegument. Pyrantel is a nematocide belonging to the tetrahydropyrimidine class. Pyrantel acts as a depolarizing, neuromuscular-blocking agent in susceptible parasites, causing paralysis and death or expulsion of the parasite.
