Webthan chemical structure.41 There is only one selective COX-2 inhibitor currently available, celecoxib (Celebrex®). In addition, recent evidence suggests that some of the older NSAIDs such as diclofenac and meloxicam show some selectivity towards the COX-2 enzyme.41 Due to the variability in NSAID half-life WebThe objective was to compare AKI risk between selective and non-selective NSAIDs using a laboratory-based definition of AKI. Methods: From a cohort of 1 459 271 new NSAID users, we identified 22 824 cases of AKI (97% male; mean age: 63 years), and 336 734 matched controls between 2000 and 2006.
Webdifferences observed were for rofecoxib compared to naproxen: OR, 95% CI: 5.39 (2.08, 14.02) and for valdecoxib compared to diclofenac OR, 95% CI: 0.14 (0.03, 0.73). However, these individual comparisons are limited by the small number of events, e.g. one event in the valdecoxib arm in the WebNSAIDs are antiinflammatory, antipyretic, and analgesic via COX-2 inhibition and have antiplatelet activity via COX-1 inhibition. For clinical decision-making, NSAIDs can be divided into three major groups: classical nonselective agents, newer COX-2 preferential drugs, and even newer COX-2 selective coxibs. GI Toxicity of Available NSAIDs
WebHazard ratios (95% CIs) for ischemic stroke were 1.68 (1.05-2.69) for nonselective and 4.54 (2.06-9.98) for COX-2-selective NSAIDs. For individual NSAIDs, current use of the nonselective naproxen (HR, 2.63; 95% CI, 1.47-4.72) and the COX-2-selective to rofecoxib (HR, 3.38; 95% CI, 1.48-7.74) was associated with a greater risk of stroke. Web22 feb. 2024 · Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit cyclooxygenase enzymes (COX, including COX-1 and COX-2) and are classified as COX-2-selective and nonselective NSAIDs based on their selectivity for COX-2 inhibition.
