ABSTRACT

Veterinary dosage forms are drug preparations designed for use in, or topical application to, one or more species of domestic animal and/or other species of veterinary interest. Although the majority of drugs available as veterinary dosage forms were initially developed for use in humans, based on experimental findings in laboratory animals, some drugs have been developed specifically for veterinary use. The type of dosage form, the route of administration, and site of injection of parenteral preparations depend on the animal species or group of related species. The anatomical arrangement of the gastrointestinal tract and associated digestive physiology govern the pattern of drug absorption. The oral route of drug administration is safer than parenteral routes and avoids tissue irritation at injection sites. A transdermal therapeutic system is a rate-controlled drug-delivery system that, applied to the surface of the skin, continuously releases the drug at a rate that will provide a desired steady-state plasma concentration for a specified duration.
