Do you cogitate the class of coxibs (pain killer approaching arcoxia and celebrex) are out of danger?
Answers:
Although the "coxibs" are used to reduce backache, they're not really pain killer, per se: they are non-steroidal anti-inflammatory drugs. They inhibit the generation of prostaglandins, which are (among other things) signaling compounds the body uses surrounded by inflammation--which then generate the pain.
Unlike ibuprofen and naproxen and other, in advance, drugs of this class, the coxibs are somewhat selective in which of the enzymes that are involved contained by prostaglandin they inhibit. There are two main forms of cyclo-oxygenase, type 1 and type 2: COX1 and COX2 for short. The coxibs primarily inhibit COX2. Turns out, that's easier on your stomach, but harder on some blood vessel.
Are they safe? At fair doses, for reasonable period, yes. At the doses and durations used in the studies that showed Vioxx and Bextra (two other coxibs) be potentially dangerous (4 times the usual and customary dose, for years: the hope be that it would prevent people next to familial polyposis from getting cancer, and it did reduce the risk, but not other by an acceptable means), apparently not.
It be, I believe, Paracelsus who pointed out that the only difference between a poison and a medication was knowing the proper dose..
they r generallly safer than previous classmates of NSAIDs(e.g. indomethacin, ibuprofen.), because they do not cause GI bleeding. but they enhance platelet agregation and may be destructive for patients at risk for coronary artery occlusion.
