ABSTRACT Adverse reactions to nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly observed, particularly among patients with chronic urticaria or asthma. The identification of a safe and reliable alternative is a frequent problem in clinical practice. Our aim was to investigate the clinical tolerability of etoricoxib, a new selective cyclooxygenase-2 inhibitor, in a group of patients with well-established NSAID hypersensitivity.
We assessed 31 adults (21 women and 10 men) who reported one or more adverse reactions to NSAIDs, manifested as cutaneous, respiratory or anaphylactic symptoms. Sixteen of them reported reactions to a single NSAID (single reactors) and 15 to more than one NSAID (multiple reactors); the most frequently involved drug was acetylsalicylic acid. First, each patient underwent allergologic tests (skin and/or oral challenge tests) with culprit NSAIDs and then tolerability tests with increasing doses of etoricoxib up to 120 mg. All challenges were performed under single-blind, placebo-controlled conditions.
NSAID hypersensitivity was diagnosed in all 31 patients: 3 displayed positive results to pyrazolone skin tests and the other 28 to challenges with culprit NSAIDs. None reacted to either placebos or etoricoxib.
Etoricoxib seems to be a safe alternative for patients with well-demonstrated NSAID hypersensitivity.

    ABSTRACT: BACKGROUND: COX-2 inhibitors are safe alternatives in patients with cross-reactive non-steroidal anti-inflammatory drug (NSAID) hypersensitivity. These drugs are recommended to these patients after negative drug provocation tests (DPTs). However, cumulative data on encouraging results about the safety of COX-2 inhibitors in the majority of these patients bring the idea as to whether a DPT is always mandatory for introducing these drugs in all patients with cross-reactive NSAID hypersensitivity. OBJECTIVE: To document the safety of COX-2 inhibitors currently available and to check whether or not any factor predicts a positive response. METHODS: This study included the retrospective analysis of cases with cross-reactive NSAID hypersensitivity who underwent DPTs with COX-2 inhibitors in order to find safe alternatives. DPTs were single-blinded and placebo controlled. RESULTS: The study group consisted of 309 patients. COX-2 inhibitors were well tolerated in the majority of the patients [nimesulide: 91.9%; meloxicam: 90.2%; rofecoxib: 94.9%; and celecoxib: 94.9%)]. Twenty-five patients (30 provocations) reacted to COX-2 inhibitors. None of the factors were found be associated with positive response. CONCLUSION: Our results suggest to follow the traditional DPT method to introduce COX-2 inhibitors for finding safe alternatives in all patients with cross-reactive NSAID hypersensitivity before prescription as uncertainty of any predictive factor for a positive response continues. However, these tests should be performed in hospital settings in which emergency equipment and experienced personnel are available.

    ABSTRACT: Non-steroidal anti-inflammatory drugs (NSAIDs) frequently cause adverse drug reactions. Many studies have shown that drugs which selectively inhibit the cyclooxygenase-2 enzyme (COX-2) are safe alternatives in the majority of patients. However, hypersensitivity reactions to COX-2 inhibitors have been published. Hardly any data are available regarding the safety of alternatives in case of COX-2 inhibitor hypersensitivity. We aimed to investigate the tolerance to COX-2 inhibitors in patients with non-selective NSAID hypersensitivity. Furthermore, in COX-2 hypersensitive patients tolerance of a second COX-2 inhibitor was investigated. We retrospectively analyzed 91 patients with proven non-selective NSAID hypersensitivity that underwent oral challenges with a COX-2 inhibitor. Patients with intolerance to the first challenged COX-2 inhibitor received a second challenge with a different COX-2 inhibitor. 19 out of 91 (21% ) patients had a positive reaction to the first oral challenge with a COX-2 inhibitor. 14 of them underwent a second challenge with a different COX-2 inhibitor and 12 (86% ) did not react. A relatively high percentage (21% ) of the non-selective NSAID hypersensitive patients did not tolerate a COX-2 inhibitor and oral challenge is advised prior to prescription of a COX-2 inhibitor. For the majority of patients reacting to a COX-2 inhibitor an alternative can be found.

    ABSTRACT: Introduction: Nonsteroidal anti-inflammatory drugs (NSAIDs) are first-line therapies in the management of patients with ankylosing spondylitis. This chronic inflammatory skeletal disorder, a subtype of spondyloarthritis, is characterized by inflammatory back pain and affects young adults causing important suffering and disability. Long-term use of conventional NSAIDs is associated with a risk of gastrointestinal complications. Etoricoxib is a specific cyclooxygenase 2 inhibitor with strong anti-inflammatory effects and a favorable pharmacokinetic profile for the management of inflammatory disorders. The drug has been associated with reduced severe gastrointestinal adverse events. However, the cardiovascular safety of cyclooxygenase 2 inhibitors has been debated. Areas covered: This review discusses etoricoxib in the treatment of ankylosing spondylitis. Literature searches were performed in PubMed, Web of Science, and the Cochrane library based on the terms "etoricoxib" and "ankylosing spondylitis" or "spondyloarthritis" as well as "safety" and "side-effects." Expert opinion: Etoricoxib is useful in the first-line management of ankylosing spondylitis patients. Its anti-inflammatory effects and relative protection against severe gastrointestinal side effects should be balanced with negative effects on the cardiovascular system and an overall subjective tolerance not better than that of conventional NSAIDs. Whether etoricoxib will also become a mainstay in the prevention of structural damage in ankylosing spondylitis is not yet clear.
