Pharmacology and therapeutics of non-steroidal anti-inflammatory drugs in the dog and cat 2 : Individual agents

Abstract

The general pharmacology of the non-steroidal anti-inflammatory drugs (NSAIDs) used in dogs and cats has been described in part 1 of this review (Lees and others 1991). This paper outlines the properties of the individual agents as they are used in small animal practice. The NSAIDs which have been used extensively in small animals include the older agents such as Aspirin, cinchophen and phenylbutazone. These agents have previously been used empirically by extrapolation of dosages from other species and by clinical experience. Studies are now available which provide a scientific rationale for the dosage rate recommended. A number of new drugs have recently been licensed for use in the dog or may be licensed in the near future. These include flunixin, carprofen and tolfenamic acid and the data generated from these products provides very useful information for formulating I effective dosage regimens. There are also some NSAIDs such as piroxicam which have been investigated in the dog because they have particular properties which may be of use in common clinical conditions and others, such as Paracetamol and Ibuprofen, which are readily available to the public and which owners may administer to dogs or cats at toxic doses
