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 controls the most important dog worms such as the roundworms Toxocara canis and Toxascaris leonina, 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.
Oxantel is a narrow-spectrum anthelmintic introduced in the 1970s (by PFIZER → ZOETIS) that belongs to the chemical class of the tetrahydropyrimidines. It is particularly effective against whipworms (Trichuris vulpis), but usually not sufficiently effective against other nematode species. Oxantel is scarcely used in pets, and not used at all in livestock or agriculture. Oxantel is not effective against tapeworms.
Praziquantel is a veteran isoquinoline anthelmintic introduced in the 1970s (by BAYER). It is still the most effective and most vastly used parasiticide against tapeworms, but without any efficacy against roundworms, fleas or ticks. Praziquantel adds efficacy against tapeworms (Dipylidium caninum, Taenia pisiformis, etc.) but has no efficacy whatsoever against roundworms, hookworms or whipworms. It is the anthelmintic most vastly used against tapeworms in pets. There are hundreds of antiparasitic brands for pets containing praziquantel.
Pyrantel, oxantel and praziquantel 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.
