COMMENTS
VETSCRIPTION SURE SHOT liquid wormer for cats is a generic wormer from SERGEANT'S with piperazine (citrate), a veteran anthelmintic effective only against ascarid roundworms (Toxocara cati, Toxascaris leonina), but not against hookworms or tapeworms.
Piperazine was already used as a human medicine at the end of the 19th century. Its anthelmintic properties for animals were discovered in the 1950's. It is still used on livestock and pets, although it has been vastly replaced with more effective compounds, especially in ruminants (cattle, sheep and goats). It is also used in anthelmintics for humans, but also in antidepressants, antihistamines, antipsychotics, etc. Piperazine derivatives are also used in plastics, resins, and other industrial materials, as well as an adulterant in the psychedelic drug scene.
Piperazine as well as pyrantel and the benzimidazoles (e.g. fenbendazole, febantel, albendazole, mebendazole, etc.) has no residual effect, i.e. it acts against the worms during a few hours after administration but is 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.
