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.

Allantoin is a metabolic intermediate of a wide variety of organims: from bacteria to vegetals and animals. Allantoin is a skin active ingridient with keratolytic, moisturizing, anti-irritant properties, promotes renewal of epidermal cell and accelerates wounds healing. Allantoin possesses one chiral center thereby exists in the two enantiomeric forms R-(-) and S-( ). Enzymes that catalyze the formation of (S)-allantoin from the product of the urate oxidase reaction have been identified. The two proteins encoded by mouse genes catalyze two consecutive steps following urate oxidation to 5-hydroxyisourate (HIU): hydrolysis of HIU to give 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU) and decarboxylation of OHCU to give S-( )-allantoin. Urate oxidation produces racemic allantoin on a time scale of hours, whereas the full enzymatic complement produces dextrorotatory allantoin on a time scale of seconds. Scioderm is developing Allantoin (Zorblisa; SD-101), as a novel topical therapy for patients with epidermolysis bullosa.

Diethyltoluamide (DEET) is an insect repellent used to keep insects away. This product is effective against mosquitoes, biting flies (gnats, sandflies, deer flies, stable flies, black flies), ticks, harvest mites, and fleas. DEET is absorbed through the skin. DEET has few adverse effects when applied as directed. The most common problem is local skin irritation, including erythema and pruritis, at the site of application.

Perflunafene is a perfluorocarbon that can absorb, transport, and release oxygen and carbon dioxide. Perflunafene is a can be used as an alternative to red blood cell preparations to improve gaseous transport, in particular oxygen supply, to the tissues. Intra-ocular injection of perflunafene is used to provide temporary tamponade in ophthalmic procedures such as retinal re-attachment. Perflunafene and perfluamine have been used together for their oxygen-carrying properties in blood substitute preparations and to prevent myocardial ischaemia during percutaneous transluminal coronary angioplasty.

Zeaxanthin is one of the most common carotenoid alcohols found in nature. It is synthesized in plants and some micro-organisms. Lutein and Zeaxanthin are found in the macula of the human retina, as well as the human crystalline lens. They play a role in protection against age-related macular degeneration (ARMD) and cataract formation. The antioxidant properties of lutein and zeaxanthin together with ocular antioxidants (selenium, zinc, copper, vitamin A, C, E, etc.) inhibit free radical damage caused by light and oxygen. Zeaxanthin supplements are typically taken on the supposition of supporting eye health. It is is Generally Recognized As Safe by FDA.

Troclosene is chlorinated hydroxytriazine and it is used as a source of free available chlorine, in the form of hypochlorous acid, for the disinfection of water. It kills bacteria, bacterial spores, cysts, algae, fungi, protozoa and virus and are especially lethal to Entamoeba histolytica. Troclosene kills mastitis-causing organisms. It is now widely available for household water treatment. It does not prevent diarrhea but improved water quality.

Resveratrol, a natural non-flavonoid polyphenol, exhibits a wide range of beneficial properties as an anticancer agent, a platelet anti-aggregation agent, and an antioxidant, as well as its anti-aging, anti-inflammatory, antiallergenic. This compound is in phase III clinical trials in combination with carboxymethyl-β-glucan for improving nasal symptoms in children with pollen-induced allergic rhinitis. Also in phase III clinical trial in the treatment of painful knee osteoarthritis and in type 2 diabetic patients. It has been demonstrated that resveratrol may prevent type 2 diabetic by targeting Sirtuin type 1 (SIRT1), indicating that SIRT1 may be a novel therapeutic target for diabetes prevention.

Cypermethrin is a synthetic, pyrethroid insecticide that has high insecticidal activity, low avian and mammalian toxicity. Cypermethrin works by quickly affecting the insect’s central nervous system. The major target site of cypermethrin is the sodium channel of the nerve membrane. A sodium channel exposed to cypermethrin can remain open much longer, even up to several seconds. It is used to control many pests including lepidopterous pests of cotton, fruit, and vegetable crops. In veterinary, it is applied topically for the control of ectoparasites such as ticks, fleas, lice and blowflies.

Acepromazine a potent neuroleptic agent with a low order of toxicity, is of particular value in the tranquilization of dogs, cats and horses. Its rapid action and lack of hypnotic effect are added advantages. Acepromazine is a commonly used tranquilizer/sedative in dogs, cats, horses, and other animals. Veterinarians typically prescribe acepromazine to quiet agitated animals or use it as a part of an anesthetic protocol. It is important to note that when used alone, acepromazine is not an effective pain reliever and does little if anything to relieve a pet’s anxiety or fear. Acepromazine can also be used to treat motion sickness and nausea associated with car or plane rides. The mechanism by which acepromazine decreases a pet’s alertness is not fully understood. It is thought to block dopamine receptors in the brain or inhibit the activity of dopamine in other ways.

Dichloroacetic acid, often abbreviated DCA (dichloroacetate), is an acid analog of acetic acid in which two of the three hydrogen atoms of the methyl group have been replaced by chlorine atoms. The salts and esters of dichloroacetic acid are called dichloroacetates. Salts of DCA are used as drugs since they inhibit the enzyme pyruvate dehydrogenase kinase. Early reports of its activity against brain cancer cells led patients to treat themselves with DCA, which is commercially available in non-pharmaceutical grade. A phase 1 study in 5 patients concluded that DCA was safe, but wasn't designed to establish effectiveness. DCA was approved for use in Canada in 1989 (as a topical formulation for the treatment of warts and for cauterization and removal of a wide variety of skin and tissue lesions), but was cancelled post market. DCA is a noncompetitive inhibitor of the endoplasmic reticulum enzyme HMG CoA reductase, which catalyzes the rate limiting step in cholesterol biosynthesis. DCA has been researched in adults, children, animals, and cells as a monotherapy as well as in combination with other therapies for the treatment of severe metabolic disorders including diabetes and hypercholesterolemia, lactic acidosis, certain heart conditions, and cancer. DCA has been prescribed to reduce tumour size and tumour markers, prevent angiogenesis, reduce cancer related symptoms, manage pain, and aid in palliation.
