Clinical economics review: gastrointestinal complications of non-steroidal anti-inflammatory drugs.
Non-steroidal anti-inflammatory drugs (NSAIDs) are the most widely used symptomatic remedies for rheumatic disorders. Their major side-effects involve the gastrointestinal tract and, while the stomach is often the prime focus of adverse reactions, the whole gut may be involved. A number of strategies have been used to reduce both the incidence of side-effects and their economic consequences. Decreased NSAID use can be achieved both by rational prescribing and by active promotion of other, usually non-pharmacological, methods of controlling symptoms. Prescribing NSAIDs based on their cost assumes all have equal efficacy and side-effects, which is demonstrably untrue. Picking the least toxic NSAID is more logical. Most of the larger studies and meta-analyses available concentrate on older NSAIDs and risk overlooking the advantages of newer preparations which have been shown to be cost beneficial by more comprehensive economic analyses. Misoprostol prophylaxis has been the subject of a number of economic evaluations which, until recently, were based on extrapolations rather than clinical data. There are now good clinical data available which show a small but significant reduction in major side-effects at the expense of an increase in minor but unpleasant ones. Proton pump inhibitors appear to offer the same degree of gastroprotection as misoprostol, with the additional benefit of symptom relief. Economic data regarding the costs and benefits of prophylaxis with proton pump inhibitors are not yet available. There is still a need for a more comprehensive evaluation of the benefits of NSAIDs in different clinical situations to balance against the costs of adverse reactions.
