Aspirin desensitization in aspirin-exacerbated respiratory disease.

Although aspirin desensitization was discovered in 1922, it was not until 1979 that a therapeutic use for aspirin treatment, under the protection of desensitization, was discovered. In the last 33 years, details of aspirin treatment have been refined to the point where it is now recognized and accepted as a major therapeutic intervention in the treatment of aspirin-exacerbated respiratory disease, with therapeutic efficacy in approximately two-thirds of patients. It is only effective in patients who have aspirin-exacerbated respiratory disease and none of the other nonsteroidal anti-inflammatory drugs, despite their cross-reactive inhibition of cyclooxygenase-1, can effectively take the place of aspirin.
