Abstract
The propionic acids represent the largest chemical class of nonsteroidal anti-inflammatory agents (NSAID). Several of them are widely used, both in the United States and internationally. This paper discusses observations made on fenoprofen, flurbiprofen, ibuprofen and naproxen. Of these compounds, three are racemates; the fourth, naproxen, is an enantiomer. As a group, the propionic acids, along with most members of the other classes of NSAID, produce gastrointestinal damage in most species. These lesions vary from erythema, hemorrhage and erosion to ulceration and peritonitis. As might be expected, the degree of gastrointestinal intolerance depends on many factors: the individual compound, the dose-level, the duration of the period of drug administration, and the pharmacokinetics and metabolism in a given species. For example, in our experience the rat is less tolerant of NSAID than is the monkey, and the dog is less tolerant than the rat. Gastrointestinal lesions have been seen following both parenteral and oral administration; these findings suggest that factors other than local irritation play a role in the development of lesions. Most NSAID inhibit prostaglandin cyclo-oxygenase activity, which results in a prostaglandin deficiency at the tissue level. The administration of relevant exogenous prostaglandins, such as 16,16-dimethyl PGE2, has been shown to inhibit the gastrointestinal toxicity accompanying the administration of several NSAID, including some of the propionic acids.Keywords
