Aspirin-induced asthma

In some asthma individuals, aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) that inhibit cyclooxygenase 1 (COX-1) exacerbate the condition. This distinct clinical syndrome, called aspirin-induced asthma (AIA), is characterised by an eosinophilic rhinosinusitis, nasal polyposis, aspirin hypersensitivity, and asthma.
