For the first time pharmacology is tackled as book in its own right. This multi-contributor text provides a complete source of information on drugs used in the horse. Each chapter covers a particular class of drugs or organ system, providing clinical information and discussing therapeutic strategies for managing disease conditions.The text is fully referenced and current prescribing practice for horses is backed up by scientific research published in the literature: for example, direct evidence from equine studies versus extrapolation from studies in other species is reviewed by the contributors. A formulary of generic drug names that includes dosages and routes of administration, with a special emphasis on products and dose rates approved for use in horses, is included at the end of the book.
