Background. Intolerance to acetylsalicylic acid (ASA) and other nonsteroidal anti-inflammatory drugs (NSAIDs) is a crucial problem in clinical practice. There is, therefore, a need for safer NSAIDs in patients with analgesic intolerance. Objective. To assess the safety of nimesulide, meloxicam, and rofecoxib, selective COX-2 inhibitors, in a group of ASA/NSAIDs-intolerant patients. Method. Tolerances to nimesulide, meloxicam, and rofecoxib were assessed by single-blind placebo-controlled oral challenges. One hundred twenty-seven subjects with history of adverse reaction to ASA/NSAIDs received oral challenges with nimesulide, 61 subjects were challenged with meloxicam, 51 subjects were challenged with rofecoxib, and 37 subjects were challenged with all three drugs. Placebos were given to all patients on the first day of the study. On the second day, one-fourth and three-fourths of the therapeutic doses of the active drugs (nimesulide 100 mg, meloxicam 7.5 mg, or rofecoxib 25 mg) were given at 60-minute intervals. There was at least a 3-day interval between challenge tests. Erythema, pruritus accompanied by erythema, urticaria/angioedema, rhinorrhea, nasal obstruction, sneezing, dyspnea, or cough associated with a decrease of at least 20% in the forced expiratory volume (FEV1) and hypotension were considered as positive reactions. Results. Positive reactions to the nimesulide, meloxicam, and rofecoxib challenges were observed in 18/127 (14.3%), 5/61 (8.1%), and 1/51 (2.0%) patients, respectively. In each group of nine patients, there were two patients with asthma and four who developed skin type reactions and asthmatic reactions, respectively, to the nimesulide challenge. Among five patients who reacted to the meloxicam challenge, asthmatic type reactions were detected in two asthmatics. Only one urticarial type reaction was observed with rofecoxib challenge in one patient who presented with anaphylaxis to ASA/NSAIDs.
