Pyrantel is a narrow-spectrum anthelmintic belonging to the chemical class of the tetrahydropyrimidines that was introduced in the 1960s (by PFIZER → ZOETIS). It is effective against roundworms and a few tapeworms (depending on the dose) in the gut, but not against those in other organs (e.g. the lungs, the skin, etc). It is effective efficacy against important dog worms such as the roundworms Toxocara canis and Toxascaris leonina and the hookworms Ancylostoma caninum and Uncinaria stenocephala. It is used a lot in pets and horses but rarely in livestock. There are dozens of products for pets with generic pyrantel. It is nit used in agriculture.
Pyrantel as well as benzimidazoles (e.g. febantel, albendazole, mebendazole, etc.), piperazine, and other anthelmintics have no residual effect, i.e. they act against the worms during a few hours after administration but are quickly metabolized and excreted. For this reason treatment must often be repeated for certain indications. This is in contrast with wormers containing macrocyclic lactones (e.g. milbemycin oxime, selamectin) that ensure efficacy against numerous roundworms during weeks after a single treatment.
