Camphor is a bicyclic monoterpene ketone found widely in plants, especially cinnamomum camphora. Topically, camphor is used to relieve pain. It has been used to treat warts, cold sores, hemorrhoids, and osteoarthritis. It has also been applied topically as an analgesic and an antipruritic. It has been used as a counterirritant, and to increase local blood flow. Camphor has frequently been used topically to treat respiratory tract diseases involving mucous membrane inflammation. It is sometimes used topically to treat cardiac symptoms. Camphor is also used topically as an eardrop, and for treating minor burns. In inhalation therapy, camphor is used as an antitussive. Orally, camphor is used as an expectorant, antiflatulent, and for treating respiratory tract diseases. Today, most camphor is synthetic. It is approved by the FDA as a topical antitussive. Camphor is produced synthetically from the oil of turpentine. It has been used for centuries for its medicinal features, in religious rituals, and in cooking. It is no longer used as pesticide. In 1982, the US Food and Drug Administration restricted commercial products intended for medicinal use to contain <11% camphor.

Benzocaine is a local anesthetic. It acts by blocking voltage-gated sodium ion channels in nerve endings. Benzocaine is available over-the counter for local anesthesia of oral and pharyngeal mucous membranes (sore throat, cold sores, mouth ulcers, toothache, sore gums, denture irritation), otic pain, and as a local anesthetic for surgical or diagnostic procedures. As a spray, benzocaine is used for temporary relief of pain and itching associated with minor burns, sunburn, minor cuts or scrapes, insect bites, or minor skin irritations. Topical application of benzocaine to gums or mouth may cause rare, but serious and potentially fatal adverse effect methemoglobinemia.

Resorcinol is a benzenediol. Resorcinol is commonly used in hair dyes and acne medication. Resorcinol works by breaking down rough, scaly, or hardened skin. Resorcinol also disinfects the skin to help fight infection. Resorcinol topical (for the skin) is used to treat pain and itching caused by minor cuts and scrapes, burns, insect bites, poison ivy, sunburn, or other skin irritations. Resorcinol topical is also used to treat acne, eczema, psoriasis, seborrhea, corns, calluses, warts, and other skin disorders. Resorcinol is included in the FDA final rule list of all permitted active ingredients for OTC topical acne products. Permitted combination active ingredient product - Resorcinol in 2 percent concentration in combination with sulfur in concentrations of between 3 and 8 percent. In oxidative hair dyes, resorcinol is regulated to 5% or below in practice, however, many manufacturers limit the level of free resorcinol in oxidative hair dyes to 1.25%. Resorcinol is limited to 0.5% in shampoos and hair lotions. Resorcinol is usually present in anti-acne preparations at a maximum concentration of 2%. The concentration of resorcinol can be much higher in peels, in some cases around 50%. Jessner’s solution (resorcinol in ethyl alcohol, 14% w/v; lactic acid, 14%; and salicylic acid, 14%) is commonly used in chemical peeling. A specialized medical use of resorcinol is in biological glues (gelatin–resorcinol–formaldehyde glue) for cardiovascular surgery, in particular aortic operations.

Methyl salicylate (or methyl 2-hydroxybenzoate), also known as wintergreen oil, is a natural product and is present in white wine, tea, porcini mushroom Boletus edulis, Bourbon vanilla, clary sage, red sage and fruits including cherry, apple, raspberry, papaya and plum. Methyl salicylate is topically used in combination with methanol and under brand name SALONPAS to temporarily relieves mild to moderate aches and pains of muscles and joints associated with: strains, sprains, simple backache, arthritis, bruises. The precise mechanism of action of methyl salicylate is not known, but there is suggested, that it cause dilation of the capillaries thereby increasing blood flow to the area.

Butyl chloride is an alkyl halide. It is used as a butylating agent in organic synthesis, e.g., in the manufacture of butyl cellulose. n-Butyl chloride is a veterinary antiparasitic (anthelmintic) drug. It is used for the removal of ascarids and hookworms from dogs and cats. n-Butyl chloride is marketed under tradenames NBC Kaps Wormer for dogs, Happy Jack Worm for dogs; Sergeants Sure Shot Capsules for cats and dogs.

Sarmazenil (previously known as RO 153505) was developed as a weak inverse agonist at the omega modulatory sites (benzodiazepine receptors). This compound is used in veterinary medicine in order to rapidly re-awake anesthetized animals. In addition, this compound was studied in the treatment of a moxidectin intoxication in foals. Sarmazenil was also involved in preclinical development for Alzheimer's disease in the USA. However, the information about the further development of the drug is not available.

Nifursol is an antibiotic of the nitrofuran class which inhibits the growth of the protozoa Histomonas meleagridis but is non-lethal. Although previously approved as a prophylactic feed additive for turkeys, the European Union has since banned Nifursol use in agricultural operations.

Netobimin is a carbamate compound which is used as an anthelmintic drug in veterinarymedicine. Netobimin-containing products are available as liquid suspensions which are intendedfor oral administration. Products are available for sheep and cattle. An oral dose of 7.5 mg/kg bw is recommended for the treatment of gastrointestinal infestations of roundworms and tapeworms;and 20 mg/kg bw is recommended for type II ostertagiasis and adult flukes. In order to be pharmacologically active, netobimin needs to be converted to the broad spectrumanthelmintic drug albendazole, by the splitting off of a side-chain and the formation of abenzimidazole group. This occurs naturally in the ruminant gut.

Parvaquone, an antitheilerial compound that was developed for the treatment of East Coast fever. Experiments on animals have shown that this drug was effective in the treatment of cattle infected with Theileria annulata.

As a narcotic antagonist similar in action to naloxone, DIPRENORPHINE is used to remobilize animals after analgesia by super-potent opioid analgesics such as etorphine and carfentanil. It is not used in humans. Diprenorphine binds approximately equally to the three subtypes of opioid receptors (mu, delta, and kappa) and antagonizes them. This compound belongs to the class of organic compounds known as phenanthrenes and derivatives. These are polycyclic compounds containing a phenanthrene moiety, which is a tricyclic aromatic compound with three non-linearly fused benzene. The therapeutic efficacy of many other compounds can be decreased when used in combination with Diprenorphine (54 compounds mentioned on www.drugbank.ca).
