An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
NSAID identification on label of generic ibuprofen, an over-the-counter non-steroidal anti-inflammatory drug. Non-steroidal anti-inflammatory drugs [1] [3] (NSAID) [1] are members of a therapeutic drug class which reduces pain, [4] decreases inflammation, decreases fever, [1] and prevents blood clots.
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]
Aspirin is non-selective and irreversibly inhibits both forms [4] (but is weakly more selective for COX-1 [5]). It does so by acetylating the hydroxyl of a serine residue at the 530 amino acid position. [6] Normally COX produces prostaglandins, most of which are pro-inflammatory, and thromboxanes, which promote clotting.
[2] [3] [4] This discovery raises the possibility of developing more potent and selective drugs targeting the site. A number of arguments counted against the COX-3 hypothesis: COX-2-selective inhibitors react weakly with the COX-3 enzymatic site, because the site is identical to that in COX-1, but they are as good at reducing fever as older NSAIDs.
Naproxen, sold under the brand name Aleve among others, is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain, menstrual cramps, and inflammatory diseases such as rheumatoid arthritis, gout and fever. [8] It is taken orally. [8] It is available in immediate and delayed release formulations. [8]
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.
Oxicam is a class of non-steroidal anti-inflammatory drugs (NSAIDs), [2] meaning that they have anti-inflammatory, analgesic, and antipyretic therapeutic effects. Oxicams bind closely to plasma proteins. [1] Most oxicams are unselective inhibitors of the cyclooxygenase (COX) enzymes.
