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. It is not used in agriculture.
Febantel is a broad-spectrum anthelmintic belonging to the chemical class of the benzimidazoles that was introduced in the 1970s (by BAYER). In fact it is a pro-benzimidazole (a so-called pro-drug) that becomes a benzimidazole only once ingested by the host. It is transformed into fenbendazole in the stomach and the intestine of the host, shortly after ingestion. Febantel is effective against numerous roundworms (e.g. Toxocara canis, Toxascaris leonina), hookworms (e.g. Ancylostoma caninum, A. braziliense, Uncinaria stenocephala), and whipworms (Trichuris vulpis). Febantel is moderately used in livestock, but not in agriculture.
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. It is not used in agriculture.
Pyrantel, febantel 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.
