Introduction: In patients with NSAID-Exacerbated Respiratory Disease (N-ERD), respiratory symptoms occur as a result of the use of cyclooxygenase (COX)-1 inhibitor non-steroidal anti-inflammatory drugs (NSAIDs). Patients with N-ERD generally tolerate selective COX-2 inhibitor NSAIDs. However, respiratory symptoms may be exacerbated in patients with N-ERD due to the intake of selective COX-2 inhibitor NSAIDs. The aim of this study was to evaluate which selective or partial COX-2 inhibitor NSAID is safer in patients with N-ERD.
Materials and methods: Forty-nine patients with a history of respiratory hypersensitivity reactions to NSAIDs (N-ERD) who underwent a drug challenge test with celecoxib, nimesulide, meloxicam, and paracetamol between January 2021-April 2022 were retrospectively evaluated.
Result: Of the 49 patients who underwent the drug challenge tests, 16 (32.7%) were male and 33 (67.3%) were female and the mean age was 37.67 ± 11.62 years. The most common comorbidities were chronic urticaria [n= 21 (42.9%)] and allergic rhinitis [n= 21 (42.9%)]. As a result of drug challenge tests, celecoxib, nimesulide, meloxicam, and paracetamol drug challenge tests were positive in 2 (4.1%), 8 (16.3%), 7 (14.3%) and 11 (22.4) patients, respectively. The rate of allergic reaction to celecoxib was statistically significantly lower than other drugs (p= 0.001). In paired comparisons of the drugs, the allergic reaction rate with celecoxib was statistically significantly lower than with nimesulide (p= 0.031) and paracetamol (p= 0.004).
Conclusions: Selective COX-2 inhibitor NSAIDs are safe in patients with N-ERD. NSAIDs should be prescribed to these patients following general medical precautions and drug challenge tests.
