The mechanisms of aspirin-intolerant asthma and its management.

Aspirin is one of the most widely used medications in the world. Adverse effects related to aspirin use were described almost concurrently with its first use. The most common side effects are gastrointestinal and renal, but adverse respiratory effects are not uncommon, and approximately 10% of adult asthmatics are aspirin intolerant. Many of these patients present with the so-called aspirin triad of aspirin sensitivity, chronic rhinosinusitis with associated nasal polyposis, and severe asthma. This paper provides a review of recent investigations into the pathogenesis of this process, which have furthered our understanding of the mechanisms and management of aspirin-induced asthma.
