Clorsulon is a compound belonging to the benzenesulphonamide family. It is used in veterinary medicine for the treatment of liver fluke (monotherapy), gasrtointestinal and lung worms, lice, grubs and mites (in combination with ivermectin) in cattles. Clorsulon inhibits the enzymes involved in the glycolytic pathways of the common liver fluke (Fasciola hepatica or Fasciola gigantica), namely phosphoglycerate kinase and phosphoglyceromutase.
