  2. Cyclooxygenase-2 inhibitor - Wikipedia

    en.wikipedia.org/wiki/Cyclooxygenase-2_inhibitor

    The existing nonsteroidal anti-inflammatory drugs differ in their relative specificities for COX-2 and COX-1; while aspirin and ibuprofen inhibit COX-2 and COX-1 enzymes, other NSAIDs appear to have partial COX-2 specificity, particularly meloxicam . [39] Aspirin is ≈170-fold more potent in inhibiting COX-1 than COX-2. [40]

  3. Nonsteroidal anti-inflammatory drug - Wikipedia

    en.wikipedia.org/wiki/Nonsteroidal_anti...

    COX-2 is an enzyme facultatively expressed in inflammation, and it is inhibition of COX-2 that produces the desirable effects of NSAIDs. [125] When nonselective COX-1/COX-2 inhibitors (such as aspirin, ibuprofen, and naproxen) lower stomach prostaglandin levels, ulcers of the stomach or duodenum and internal bleeding can result. [126]

  4. Analgesic - Wikipedia

    en.wikipedia.org/wiki/Analgesic

    These drugs have been derived from NSAIDs. The cyclooxygenase enzyme inhibited by NSAIDs was discovered to have at least two different versions: COX1 and COX2. Research suggested most of the adverse effects of NSAIDs to be mediated by blocking the COX1 (constitutive) enzyme, with the analgesic effects being mediated by the COX2 enzyme. Thus ...

  5. Discovery and development of cyclooxygenase 2 inhibitors

    en.wikipedia.org/wiki/Discovery_and_development...

    Once the COX-2 enzyme was identified, Dup-697 became the building-block for synthesis of COX-2 inhibitors. Celecoxib and rofecoxib, the first COX-2 inhibitors to reach market, were based on DuP-697. [ 5 ] [ 6 ] It took less than eight years to develop and market the first COX-2 inhibitor, with Celebrex ( celecoxib ) launched in December 1998 ...

  6. Prostaglandin antagonist - Wikipedia

    en.wikipedia.org/wiki/Prostaglandin_antagonist

    Relatively new NSAIDs, known as COX-2 selective inhibitors or coxibs, are used as specific inhibitors of the COX-2 isoform of cyclooxygenase. The development of these drugs allowed the circumvention of the negative gastrointestinal side effects of NSAIDs while still effectively reducing inflammation.

  7. Cyclooxygenase-2 - Wikipedia

    en.wikipedia.org/wiki/Cyclooxygenase-2

    Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit prostaglandin production by PTGS1 (COX-1) and PTGS2 (COX-2). NSAIDs selective for inhibition of PTGS2 (COX-2) are less likely than traditional drugs to cause gastrointestinal adverse effects, but could cause cardiovascular events, such as heart failure, myocardial infarction, and stroke.

  8. Cyclooxygenase - Wikipedia

    en.wikipedia.org/wiki/Cyclooxygenase

    Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen, exert their effects through inhibition of COX. Those that are specific to the COX-2 isozyme are called COX-2 inhibitors. The active metabolite of paracetamol is a COX inhibitor, a fact to which some or all of its therapeutic effect has been attributed. [5]

  9. Oxicam - Wikipedia

    en.wikipedia.org/wiki/Oxicam

    The exception is meloxicam with a slight (10:1) preference for COX-2, which, however, is only clinically relevant at low doses. [3] The most popular drug of the oxicam class is piroxicam. [1] Other examples include: ampiroxicam, droxicam, pivoxicam, tenoxicam, lornoxicam, [1] and meloxicam. Isoxicam has been suspended as a result of fatal skin ...
