Diethylcarbamazine is used in humans, dogs and cats for the treatment of parasitic infections, including pulmonary eosinophilia, loiasis, and lymphatic filariasis. The exact mechanism of its action is unknown, however some studies showed the involvment of inducible nitric-oxide synthase and the cyclooxygenase pathway. Although there is no information on whether the drug is marketed in the USA and Europe, it is currently used in India.
Imidacloprid is a systemic, chloro-nicotinyl insecticide used for the control of sucking insects such as fleas, aphids, whiteflies, termites, turf insects, soil insects, and some beetles. It is used on co on and vegetable crops as foliar and seed treatments, soil, structures, indoor and outdoor insect control, home gardening and pet products. It is indicated for the prevention of heartworm disease caused by Dirofilaria immitis. It kills adult fleas and is indicated for the treatment of flea infestations (Ctenocephalides felis). It is also indicated for the treatment and control of the following intestinal parasites Hookworm species, Roundworm species, Whipworms. Adverse events in animals included: malaise, vomiting, diarrhea, shaking, mydriasis, hypersalivation with abnormal neurologic signs, seizures, death, generalized hematoma of the body, and alopecia at the treatment site. Adverse reactions in humans included: burning, tingling, numbness, bad taste in the mouth, dizziness, and headache.
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.

Fenbendazole (FBZ) is a broad-spectrum benzimidazole antiparasitic drug currently approved for use in numerous animal species, including rodents. Although nematodes, and in particular pinworms, are the main endoparasites of concern in laboratory rodents, FBZ also is indicated for use in other animal species against a wide spectrum of nematodes, tapeworms, flukes, and protozoa (Giardia duodenalis, Encephalitozoon intestinalis). The molecular mode of fenbendazole action consists in binding of beta-tubulin monomer prior to dimerisation with alfa-tubulin which blocks subsequent microtubule formation. These microtubules are important organelles involved in the motility, the division and the secretion processes of cells in all living organisms. In the worms the blocking of microtubules perturbs the uptake of glucose, which eventually empties the glycogen reserves. This blocks the whole energy management mechanism of the worms that are paralyzed and die or are expelled. FBZ have a greater binding to nematode as compared to mammalian tubulin at 37°C. The oral LD50 of p-OH fenbendazole was >10 000 mg/kg b.w. in mice and rats.

Ivermectin B1B (dihydroavermectin B1b) is the minor component (<10%) of the commercial anthelmintic, ivermectin. Members of the avermectin/milbemycin anthelmintic class exert their anthelmintic effects by binding to glutamate-gated chloride channels expressed on nematode neurons and pharyngeal muscle cells. The avermectin/milbemycins are also potent insecticides. In vitro, the B1b (25-isopropyl) analog is slightly more potent than the 25-sec-butyl (B1a) analog as an inhibitor of nematode larval development and paralysis, and also a more sensitive probe for ivermectin resistance.
22,23-dihydro-avermectin B1a is a major form of Ivermectin mixture (more than 90%). It is a broad-spectrum anthelmintic (worms), microfilaricide (heartworms), and miticide (mites) drug, used for horses, cattle, pigs, household pets. Ivermectin used in humans, especially for river blindness. Ivermectin binds selectively and with high affinity to glutamate-gated chloride ion channels in invertebrate muscle and nerve cells of the microfilaria.
