Is meloxicam a COX-1 or COX-2 inhibitor?
A third COX-2–selective inhibitor, meloxicam, has recently been introduced. COX-2 inhibitors and traditional NSAIDs do not appear to differ significantly in their effectiveness in alleviating pain or inflammation. They have similar gastrointestinal side effects, including abdominal pain, dyspepsia and diarrhea.
What drugs are selective COX-2 inhibitors?
Selective COX-2 inhibitors currently used in the clinic are the sulphonamides celecoxib and valdecoxib (parecoxib is a prodrug of valdecoxib), as well as the methylsulphones rofecoxib and etoricoxib.
What is the chemical structure of meloxicam?
Meloxicam (4-hydroxy-2-methyl-N-(5-methyl-1,3-thiazol-2-yl)-2H-1,2-benzothiazine-3-carboxamide-1,1-dioxide) is a piroxicam analogue, in which the pyridyl group in the amidic part of the molecule was substituted with the 5-methylthiazole system.
Which of the following NSAID is a selective COX-2 derivative?
Celecoxib is the only selective COX-2 inhibitor available in the United States. NSAIDs are effective in musculoskeletal pain and as an abortive treatment of migraine headaches.
How selective is meloxicam?
A relatively selective COX-2 inhibitor, such as meloxicam, may combine antiinflammatory efficacy with improved tolerability. In volunteers, indomethacin 75 mg, but not meloxicam 7.5 mg, inhibited renal prostaglandin E2 excretion and platelet aggregation (COX-1 mediated effects).
What class of drug is meloxicam?
Meloxicam is in a class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by stopping the body’s production of a substance that causes pain, fever, and inflammation.
How is meloxicam metabolized?
Meloxicam is metabolized to four biologically inactive metabolites and excreted in urine and faeces with an elimination half-life (t1/2) of around 20 h. This is reflected in a total plasma clearance of 7 to 8 ml/min. Steady state is achieved within 3 to 5 days.
How does ibuprofen inhibit COX?
Ibuprofen (IBP) has classically fallen into the time-independent class of COX inhibitors as it binds rapidly and reversibly to COX and acts as a competitive inhibitor of arachidonic acid (AA) oxygenation (Gierse et al., 1999; Prusakiewicz et al., 2009).
What is the mechanism of action of meloxicam?
Meloxicam inhibits prostaglandin synthetase (cylooxygenase 1 and 2) enzymes leading to a decreased synthesis of prostaglandins, which normally mediate painful inflammatory symptoms. As prostaglandins sensitize neuronal pain receptors, inhibition of their synthesis leads to analgesic and inflammatory effects.

Is meloxicam metabolized by the liver?
Metabolism of Meloxicam in human liver involves cytochromes P4502C9 and 3A4. Xenobiotica.
Is naproxen a COX-2 inhibitor?
Introduction. Naproxen is a non-steroidal, antiinflammatory agent. It is a non-selective COX-1 and COX-2 inhibitor Mitchell et al (1993). Structurally, naproxen is a propionic acid-derived, non-steroidal, anti-inflammatory drug with a chiral center.
