Abstract

To evaluate the tolerance to piroxicam in patients with urticaria induced by analgesic and/or nonsteroidal antiinflammatory drugs (NSAIDs), we carried out a 2-year study in an outpatient clinic. All the patients referred to the clinic for study entered a protocol for evaluation of intolerance to one or more drugs. If patients were allergic to at least two different NSAIDs they were allocated to group A, but if patients were allergic to only one they were considered as having selective intolerance (group B). Either piroxicam or placebo was administered under controlled conditions to both groups. In group A, five out of 18 patients had a positive response to piroxicam. In group B, in all the 25 cases studied a good tolerance to piroxicam was shown. These results indicate that in the group with intolerance to NSAIDs piroxicam induced a positive reaction in 27% of the cases, and that this drug should be administered with caution and with a previous controlled challenge in this type of patient. Piroxicam was well tolerated in the group with selective intolerance, indicating that mechanisms other than interference with the prostaglandin synthesis and release of inflammatory mediators participate in allergic reactions to NSAIDs. © 1992.
