Introduction to Drug Formulary

Introduction to Drug Formulary



The drugs listed in this formulary represent a compilation of the more commonly used therapeutic agents in small-animal practice, without implying endorsement (or lack thereof) of specific medications. Not all drugs used in veterinary practice are included, and clinicians may infrequently or never use some of those listed.


Drugs are organized in alphabetical order by generic names, with trade names in parentheses under the generic title, and the drugs also are listed alphabetically by brand name, with a cross-reference. A brief description of the drug’s actions or indications is also provided. Canine and feline dosages are given individually. Note that total dose is the amount given to an animal in each single dose (in contrast to dose per kilogram body weight) and not the total amount of drug given for the full course of treatment. The fifth column, entitled Comments, describes commonly seen side effects, specific important observations, or other characteristics that are particularly important to the clinician. A sixth column, entitled How the Drug Is Supplied, includes commonly available sizes and formulations. Abbreviations used in the formulary are first defined on this page for the reader’s reference.


Entries that are preceded by letters or modifiers are listed according to the principal word in the name of the drug. For example, L-asparaginase is listed under the letter A, DL-methionine is listed under the letter M, and S-adenosyl methionine is also listed under the letter M. Entries that are preceded by numbers are listed without the number (e.g., 4-methylpyrazole is listed under M).


While every effort has been made to include clinically useful, important, and accurate information, a comprehensive review of the details of individual drugs is too voluminous to be listed in this format. Therefore, it remains the prescriber’s and clinician’s responsibility to ensure that the particulars of any drug are appropriate for the intended application. The clinician should recheck drug dosages for accuracy as well as for specific indications, contraindications, and warnings. Drugs are listed not only by their licensed uses but also by commonly practiced uses. Again, the clinician needs to identify the specific and recommended indications for each drug by reviewing relevant information (e.g., product insert, primary sources) before prescribing, recommending, or using a drug.


Drugs, dosages, comments, and side effects are taken from several sources: (1) the clinical experience of the editor and previous redactors of this formulary; (2) drug-related information from the other sections of this textbook; (3) Ettinger SJ, Feldman, EC: Textbook of veterinary internal medicine, ed 6, St Louis, 2005, Saunders; (4) PDR Staff: Physician’s desk reference, ed 64, Williston, VT, 2009, PDR Network; (5) Plumb DC: Veterinary drug handbook, ed 6, Ames, Iowa, 2008, Blackwell; (6) Kirk RW, Bonagura JD, editors: Current veterinary therapy IX-XIV, Philadelphia and St Louis, 1986-2008, Saunders; (7) Greene CE, editor: Infectious diseases of the dog and cat, ed 3, St Louis, 2006, Saunders; and (8) websites medlineplus.gov, www.medicinenet.com, www.drugs.com, and www.rxlist.com.
