Dymanthine (Thelmesan) is an Anthelmintic, it is prepared as the hydrochloride and has some activity against hookworm infection, ascariasis, trichuriasis and hymenolepiasis. The drug appears to be safe, well tolerated and to cause few side effects (nausea, vomiting, headache, diarrhea, giddiness).

Flubendazole is an anthelmintic that is used to treat worm infection in humans. It is available OTC in Europe. Flubendazole is registered and sold in Europe (EMEA) as Fluvermal (Johnson and Johnson, Sante Bea). A 100mg dose of Fluvermal is most commonly proscribed for treating pinwoms (Enterobius vermiculus)). This is followed by a second dose of 100mg 15-21 days later to ensure reinfection is avoided, as flubendazole does not kill pinworm eggs. 100mg taken 3 times a day for 3 days is effective against larger nematodes, but only marginally effective against tapeworms. Flubendazole was validated for its anti-proliferative efficacy in MDA-MB-231 cells. Moreover, Flubendazole induced autophagy and increased ROS production. In silico analysis and experimental validation together demonstrate that Flubendazole can target autophagy-related protein 4B (Atg4B) in MDA-MB-231 cells and induce autophagy, which may shed light on the exploration of this compound as a potential new Atg4B targeted drug for future triple-negative breast cancer (TNBC) therapy.

Melarsomine (melarsomine dihydrochloride) is an organic arsenical chemotherapeutic agent and is a trypanocidal antiparasitic drug. As of 2016 DIROBAN, a generic melarsomine dihydrochloride product, is the only FDA-approved treatment for adult heartworm (Dirofilaria immitis) infection in dogs. It is not approved for treatment in cats, or dogs in late-stage infection. It is marketed by Merial under the trade name Immiticide and is not currently available in the U.S. due to a manufacturing shortage. Sponsored by Anzac Animal Health, LLC and distributed by Zoetis, Inc., DIROBAN is a prescription animal drug supplied as a sterile powder that must be reconstituted with an accompanying sterile water diluent. The exact mode of action on D. immitis is unknown. Post-treatment mortality due to thromboembolism and/or progression of the underlying disease may occur in 10 to 20% of the Class 3 patients treated with DIROBAN.

Sarolaner is a member of the isoxazoline class of parasiticides. It is sold under the brand name Simparica, indicated for the treatment of tick infestations (Dermacentor reticulatus, Ixodes hexagonus, Ixodes ricinus and Rhipicephalus sanguineus), as well as of flea infestations (Ctenocephalides felis and Ctenocephalides canis) in dogs. The primary target of action of sarolaner in insects and acarines is functional blockade of ligand-gated chloride channels (GABA-receptors and glutamate-receptors). Sarolaner blocks GABA- and glutamate-gated chloride channels in the central nervous system of insects and acarines. Disruption of these receptors by sarolaner prevents the uptake of chloride ions by GABA and glutamate gated ion channels, thus resulting in increased nerve stimulation and death of the target parasite. Sarolaner exhibits higher functional potency to block insect/acarine receptors compared to mammalian receptors.

Ponazuril, sold by the Bayer Corporation under the trade name Marquis, was the first FDA-approved treatment for equine protozoal myeloencephalitis (EPM) in horse, caused by Sarcocystis neurona. Also this drug was used in animals such as cats, dogs against coccidia, an intestinal parasite. Coccidia treatment is far shorter than treatment for EPM.

Monensin is an antibiotic produced as a byproduct of fermentation by Streptomyces cinnamonensis and belongs to a family of drugs known as polyether antibiotics or ionophores. The drug was approved by FDA for the prevention of coccidiosis in turkeys, chickens, quail, cattle, goats, calves (Coban, Rumensin). The exact mechanism of monesin action is unknown, however there are several hypotesis, which includes the inhibition of K+ transport, the inhibition of the transport of carbohydrates across the host cell membrane, the interruption host cell invasion by sporozoites, etc.

Morantel (1,4,5,6-tetrahydro-1-methyl-2-[2-(3-methyl-2-thienyl)ethenyl pyrimidine) is a tetrahydro-pyrimidine anthelmintic, differing from the related analogue pyrantel by the presence of a methyl group on the thiophene ring. Morantel tartrate, manufactured by Pfizer, Inc., was approved in the United States for use in cattle in 1981, and entered the market in early 1982. Three formulations have been approved in the United States: RUMATEL® Medicated Premix-88; RUMATEL Cattle Wormer Bolus, and PARATECT FLEX™ Diffuser, a sustained release bolus. It is intended to treat roundworms and tapeworms. Morantel is administered in lactating and non lactating cattle as morantel tartrate as a slow-release bolus (11.8 g morantel base per animal) or as a single oral dose of 6 to 7.5 mg morantel base/kg bw and in pigs at a single dose equivalent to 7.5 mg base/kg bw. In sheep, the citrate salt is administered at a single dose equivalent to 5 to 6 mg morantel base/kg bw. Morantel acts as a potent agonist at the acetylcholine receptors on the muscle cells of nematodes. Activation of the acetylcholine receptors induces a prolonged, spastic paralysis of the worms and expulsion from the host. It also been reported to block neurotransmission in vertebrates, to possess nicotine-like properties and to mimic acetylcholine at receptors in autonomic ganglia, adrenal medullae and respiratory tissues. Morantel and its salts are not used in human medicines.

Oxfendazole is a broad spectrum benzimidazole anthelmintic. Oxfendazole has broad-spectrum activity against inhibited larval stages of gastrointestinal roundworms, tapeworms, and lungworms in many animal species at doses between 4.5–10 mg/kg.

Robenidine (l,3-6ts (p-chlorobenzylidenamino) guanidine hydrochloride) is an effective anticoccidial, first introduced by Kantor, Kennett, Waletzky & Tomcufcik (1970). It does not affect the earliest stages in the coccidial life-cycle and its main activity is against the almost mature first generation schizont. It is used as an aid in the prevention of coccidiosis caused by Eimeria mivati, E. brunetti, E. tenella, E. acervulina, E. maxima and E. necatrix in broiler chickens.
