COMMENTS

EASY WORMER GRANULES is a cat wormer from JOHNSON'S VETERINARY containing fenbendazole, a generic version of MERCKS's PANACUR C.

Fenbendazole is a veteran benzimidazole introduced in the 1970s (by HOECHST). It is a broad-spectrum anthelmintic effective against most gastrointestinal worms that infect pets. Depending on the dose this includes roundworms (Toxocara cati, Toxascaris leonina), hookworms (Ancylostoma spp, Uncinaria stenocephala), lungworms (Aelurostrongylus abstrusus) and certain tapeworms (e.g. Taenia spp). It is abundantly used in livestock and horses, moderately in pets. It is not used in agriculture.

Fenbendazole and most other benzimidazoles (e.g. febantel, albendazole, mebendazole, etc.) and tetrahydropyrimidines (e.g. pyrantel, morantel, etc.) 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 protection against numerous roundworms during weeks after a single treatment.
