Febantel is a anthelminthic agent used for the treatment of parasitic worms in animals.

Phenethyl alcohol, or 2-phenylethanol, is an aromatic alcohol with a rosy scent. It is widely used in the food, fragrance, and cosmetic industries. It is used in the formulation of eye area makeup, skin care products, shampoos, perfumes, and colognes. Promising sources of natural 2-phenylethanol are microorganisms, especially yeasts, which can produce it by biosynthesis and biotransformation.

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.

Epsiprantel is a veterinary drug which is used as an antiparasitic agent. Epsiprantel in tablets (Cestex) is indicated for the removal of tapeworms in the cat (Dipylidium caninumand Taenia taeniaeformis) and dog (Dipylidium caninum and Taenia pisiformis). Epsiprantel acts directly on the tapeworm. Since it is minimally absorbed following oral administration, epsiprantel remains at the site of action within the gastrointestinal tract. Due to digestive process, tapeworm fragments or proglottids may not be readily visible in the stool. Epsiprantel is not a cholinesterase inhibitor. During the course of clinical field studies, Cestex was administered concurrently with diethylcarbamazine citrate (dogs only), anti-inflammatory agents, insecticides, and nematocides with no drug incompatibilities noted. The mechanism of action of epsiprantel appears to be similar to that of praziquantel, a drug that disrupts the regulation of calcium and other cations. Tetanic muscle contraction and paralysis occurs in the parasite, and the tegument becomes vacuolized

Ceftiofur is an antibiotic of the cephalosporin type (third generation), licensed for use in veterinary medicine only. It was first described in 1987. It is marketed by pharmaceutical company Zoetis as Excenel, Naxcel, and Excede and is also the active ingredient in that company's Spectramast LC (lactating cow formulation) and Spectramast DC (dry cow formulation) product. Ceftiofur has worldwide approvals for respiratory disease in swine, ruminants (cattle, sheep and goats) and horses and has also been approved for foot rot and metritis infections in cattle. Ceftiofur has also been approved in various countries for early mortality infections in day-old chicks and turkey poults. Ceftiofur (NAXCEL) is indicated for treatment of bovine respiratory disease (shipping fever, pneumonia) associated with Mannheimia haemolytica, Pasteurella multocida, and Histophilus somni. NAXCEL is also indicated for treatment of acute bovine interdigital necrobacillosis (foot rot, pododermatitis) associated with Fusobacterium necrophorum and Bacteroides melaninogenicus.

Enrofloxacin was developed by Bayer for the treatment of broad spectrum of bacterial infections in animals (cats and dogs). The drug exerts its action by inhibiting DNA Topoisomerase II (Gyrase) and DNA Topoisomerase IV (Topo IV), two major bacterial topoisomerase. Enrofloxacin was shown to be metabolized to ciprofloxacin and may cross the blood brain barrier in the animals.

2-Methyl-4-isothiazolin-3-one hydrochloride is an isothiazolinone based biocide and preservative used in personal care products. 2-Methyl-4-isothiazolin-3-one is also used for controlling microbial growth in water-containing solution. It is used to study the effects of tyrosine phosphorylation on focal adhesion kinase (FAK) activity in the development of neural axons and dendrites. 2-Methyl-4-isothiazolin-3-one hydrochloride (Methylisothiazolinone hydrochloride) is a common preservative used in industrial products, owing to its strong biocide effect. Contact allergy to Methylisothiazolinone hydrochloride has been reported in different occupations, including mechanics, hairdressers and healthcare workers.

Oxibendazole is an anthelmintics drug which is used to protect against roundworms, strongyles, threadworms, pinworms and lungworm infestations in horses and other domestic pets. Oxibendazole causes degenerative alterations in the tegument and intestinal cells of the worm by binding to the colchicine-sensitive site of tubulin, thus inhibiting its polymerization or assembly into microtubules.

Benzododecinium, a quaternary ammonium compound, is an antiseptic agent and disinfectant. Benzododecinium is used as preservative in different pharmaceutical formulations. Thus, the dispenser of Timoptol-LA, used for the treatment of patients with ocular hypertension, contains benzododecinium bromide as a preservative. It is used as preservative and the corneal permeability enhancer in formulation. Benzododecinium is effective against gram-positive microbes.

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.
