Fen-IverQuantel is a Combination active roundworm, bot and tapeworm paste for horses.
 
Active Ingredient
An aniseed-flavoured gel formulation for oral administration. Each 30 mL syringe delivers 120 mg Ivermectin, 1500 mg Praziquantel, and 6000 mg Fenbendazole sufficient to treat a horse of 600 kg bodyweight.
 
Actions
Ivermectin acts as a gamma amino-butyric acid (GABA) agonist that causes neuromuscular blockage, which causes paralysis and death of the parasite. Praziquantel kills cestodes by disrupting the integrity of the tegument and by interfering with glucose metabolism. Fenbendazole interferes with the energy metabolism of the parasite, causing it to starve to death.

These include: Large strongyles, including adult and arterial larval stages of Strongylus vulgaris, adult and tissue larval stages of S. edentates, adult of S. equinus and Triodontophorus spp: Small strongyles, including benzimidazole resistant strains and adult and immature stages of Cyathostomum spp, Cylicocyclus spp, Cylicostephanus spp, Cylicodontophorus spp, and Gyalocephalus spp: Dictyocaulus arnfeldi (adult and immature), Oxyuris equi (adult and immature) Parascaris equorum (adult), Trichostrongylus axei (adult), Hebronema muscae, Strongyloides westeri, Gasterophilus spp. (oral and gastric stages) and Anoplocephala perfoliate.
