Summary

Chronic use of aspirin and other so-called nonsteroidal anti-inflammatory drugs (NSAIDs) can cause stomach bleeding, kidney failure, or worse. The problem is that the compounds not only subdue a key enzyme involved in triggering inflammation and pain; they also stifle a nearly identical enzyme that helps maintain tissues such as the stomach lining. Now researchers at a number of drug companies are making progress toward “superaspirins”—compounds capable of discriminating between the twin enzymes, which would enable them to fight pain without causing dangerous side effects.
