Among the antiparasitic drugs used for the control of parasitic worms (anthelmintics ) that affect dogs and cats , there are four major groups based on their spectrum of activity:
Heartworms preventatives (against Dirofilaria spp ), often controlling also some roundworm species.
Wormers against roundworms (Toxocara canis , Toxocara cati ), hookworms (Ancylostoma spp , Uncinaria stenocephala ) whipworms (Trichuris spp ), lungworms (Angiostrongylus vasorum ) and other nematodes.
Wormers against tapeworms (Dipylidium caninum , Echinococcus granulosus , Echinococcus multilocularis , Mesocestoides spp , Taenia spp, etc ).
All-Wormers against both roundworms and tapeworms.
Active ingredients used in anthelmintic drugs
Heartworm preventatives contain all macrocyclic lactones , mainly ivermectin , milbemycin oxime , moxidectin , abamectin or selamectin . The spectrum of activity of these active ingredients at the recommended dose for heartworm prevention is different: some are ineffective against most roundworm (e.g. ivermectin), others control a several roundworm species as well.
Anthelmintics against roundworms contain mainly pyrantel , febantel , fenbendazole , emodepside , piperazine and in some countries also mebendazole , levamisole and a few other active ingredients.
Anthelmintics against tapeworms contain mainly praziquantel , a few ones niclosamide or epsiprantel .
All-wormers contain mostly mixtures of the previously mentioned active ingredients.
Wormers that control also external parasites (e.g. fleas ) are shown in another section in this site (click here ).
This section includes articles on the most popular heartworm preventatives and wormers used in major English-speaking countries.
