Tricaine (MS-222, Tricaine-S), a water-soluble local anesthetic, is used commonly for sedation, immobilization, and anesthesia of poikilothermic animals and has been accepted as a common anesthetic for use in the cold-blooded animals. It has long been recognized as a valuable tool for the proper handling of these animals during manual spawning (fish stripping), weighing, measuring, marking, surgical operations, transport, photography, and research. Tricaine was developed by Merck as a sulfonated analog of benzocaine with high solubility in water. The main advantage of Tricaine is the short duration of action and rapid metabolism. There are many reports describing the use of Tricaine for anesthetizing poikilothermic animals because it is a safe agent for immersion anesthesia even though the other anesthetics such as ether, ethanol, thiopental, halothane, isoflurane, barbiturates also could be used. Amphibians could be anesthetized easily by immersion methods with Tricaine because the amphibian skin is extremely permeable and water is absorbed through the skin rather than ingested. Tricaine has been administered as an injectable agent also.

Dichlorophene is a halogenated phenolic compound that functions as a bacteriocide and fungicide in cosmetics. Dichlorophene was reported to be used in a total of five cosmetic formulations at concentrations of 0% to 1.0%. Dichlorophen is used in the treatment of tapeworm infestation in man and animals and is the basis of a preparation against athlete’s foot. As a fungicide and bactericide it is recommended for the protection of textiles and materials including horticultural benches and equipment against moulds and algae.

Brilliant Blue is an organic compound classified as a blue triarylmethane dye. It is coal tar derivative food dye; used as the di-NH4 or di-Na salts. Coloring agent. Brilliant Blue FCF, has been used in foods in the US since 1929. This color adds a distinctive, bright blue hue to beverages, beverage powders, dairy products, baked goods, dessert powders, confections, condiments, icings, syrups, jams, jellies, marmalades, liqueurs, extracts, dairy fats and oil, meat, seafood, snacks, dry mixes and seasonings, fruit preparations, convenient food, and flavors. Both the diammonium and disodium salts of FD&C Blue No. 1 are used. The disodium salt is used in foods, while the diammonium salt has limited usage in drugs and cosmetics.

Cetrimide is a quaternary ammonium compound. Cetrimide was first introduced as a combined cleanser and skin antiseptic by Barnes (1942). Cetrimide combines excellent detergent properties and minimal toxicity with a useful antiseptic action. Cetrimide affects membrane permeability allowing ‘leaking’ of essential cell constituents leading to cell death. This medication is a skin antiseptic and disinfectant prescribed for seborrhoeic dermatitis and wound cleansing. The cream has a bactericidal activity against gram-positive bacteria and incompatible with soaps and other anionic surfactants.

p-Chlorocresol (p-chloro-m-cresol; PCMC; brand name: Preventol CMK) possesses disinfectant and antiseptic properties. Chlorocresol is used in various preparations for skin disinfection and wounds. It also used as a preservative in creams and other preparations for external use which contain water. For use as a disinfectant such as a hand wash, it is commonly dissolved in alcohol in combination with other phenols. It is a moderate allergen for sensitive skin. Chlorocresol produces potentially life-threatening effects which include dermatitis, which are responsible for the discontinuation of chlorocresol therapy. The symptomatic adverse reactions produced by chlorocresol are more or less tolerable and if they become severe, they can be treated symptomatically, these include hypersensitivity reactions, irritation of eyes.

Cloprostenol is a synthetic prostaglandin analogue structurally related to Prostaglandin F2α (PGF2α), for use in cattle and horses. As a potent luteolytic agent it causes functional and morphological regression of the corpus luteum (luteolysis) in cattle and horses followed by return to oestrus and normal ovulation.
