Coxib
COX-2 inhibitors are a type of nonsteroidal anti-inflammatory drug (NSAID) that directly targets cyclooxygenase-2, COX-2, an enzyme responsible for inflammation and pain. Targeting selectivity for COX-2 reduces the risk of peptic ulceration and is the main feature of celecoxib, rofecoxib, and other members of this drug class. After several COX-2-inhibiting drugs were approved for marketing, data from clinical trials revealed that COX-2 inhibitors caused a significant increase in heart attacks and strokes, with some drugs in the class having worse risks than others. Rofecoxib (sold under the brand name Vioxx) was taken off the market in 2004 because of these concerns, while celecoxib (sold under the brand name Celebrex) and traditional NSAIDs received boxed warnings on their labels. Many COX-2-specific inhibitors have been removed from the US market. As of December 2011, only Celebrex (generic name of celecoxib) is still available for purchase in the United States.

Vioxx
Rofecoxib is a COX-2 selective nonsteroidal anti-inflammatory drug (NSAID). It was marketed by Merck & Co. to treat osteoarthritis, rheumatoid arthritis, juvenile rheumatoid arthritis, acute pain conditions, migraine, and dysmenorrhea. Rofecoxib was approved in the US by the US Food and Drug Administration (FDA) in May 1999, and was marketed under the brand names Vioxx, Ceoxx, and Ceeoxx. Rofecoxib was available by prescription in both tablet-form and as an oral suspension. Rofecoxib gained widespread use among physicians treating patients with arthritis and other conditions causing chronic or acute pain. Worldwide, over 80 million people were prescribed rofecoxib at some time. In September 2004, Merck voluntarily withdrew rofecoxib from the market because of concerns about increased risk of heart attack and stroke associated with long-term, high-dosage use. Merck withdrew the drug after disclosures that it withheld information about rofecoxib's risks from doctors and patients ...

Parecoxib
Parecoxib, sold under the brand name Dynastat among others, is a water-soluble and injectable prodrug of valdecoxib. Parecoxib is a COX2 selective inhibitor. It is injectable. It is approved through much of Europe for short term perioperative pain control. It was patented in 1996 and approved for medical use in 2002. Approval In 2005, the U.S. Food and Drug Administration (FDA) issued a letter of non-approval for parecoxib in the United States. No reasons were ever documented publicly for the non-approval, although one study noted increased occurrences of heart attacks following cardiac bypass surgery compared to placebo when high doses of parecoxib were used to control pain after surgery. Importantly, rare but severe allergic reactions (Stevens–Johnson syndrome, Lyell syndrome) have been described with valdecoxib, the molecule to which parecoxib is converted. The drug is not approved for use after cardiac surgery in Europe. All anti-inflammatory medications in the U.S. ca ...

Analgesic
An analgesic drug, also called simply an analgesic (American English), analgaesic (British English), pain reliever, or painkiller, is any member of the group of drugs used to achieve relief from pain (that is, analgesia or pain management). It is typically used to induce cooperation with a medical procedure. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owing ...

Etoricoxib
Etoricoxib, sold under the trade name Arcoxia, is a selective COX-2 inhibitor from McOLSON Research Laboratories. Currently it is approved in more than 80 countries worldwide but not in the US, where the Food and Drug Administration (FDA) has required additional safety and efficacy data for etoricoxib before it will issue approval. It was patented in 1996 and approved for medical use in 2002. Medical uses Etoricoxib is indicated for the treatment of rheumatoid arthritis, psoriatic arthritis, osteoarthritis, ankylosing spondylitis, chronic low back pain, acute pain, and gout. Approved indications differ by country. In the U.K. and Germany, it is also "used for the short term treatment of moderate pain after dental surgery" of adults. Efficacy A Cochrane review assessed the benefits of single-dose etoricoxib in reduction of acute post-operative pain in adults. Single-dose oral etoricoxib provides four times more pain relief post-operatively than placebo, with equivalent leve ...

Nonsteroidal Anti-inflammatory Drug
Non-steroidal anti-inflammatory drugs (NSAID) are members of a therapeutic drug class which reduces pain, decreases inflammation, decreases fever, and prevents blood clots. Side effects depend on the specific drug, its dose and duration of use, but largely include an increased risk of gastrointestinal ulcers and bleeds, heart attack, and kidney disease. The term ''non-steroidal'', common from around 1960, distinguishes these drugs from corticosteroids, which during the 1950s had acquired a bad reputation due to overuse and side-effect problems after their initial introduction in 1948. NSAIDs work by inhibiting the activity of cyclooxygenase enzymes (the COX-1 and COX-2 isoenzymes). In cells, these enzymes are involved in the synthesis of key biological mediators, namely prostaglandins, which are involved in inflammation, and thromboxanes, which are involved in blood clotting. There are two general types of NSAIDs available: non-selective, and COX-2 selective. Most N ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

COX-2
Prostaglandin-endoperoxide synthase 2 (prostaglandin G/H synthase and cyclooxygenase) (The HUGO official symbol is PTGS2; HGNC ID, HGNC:9605), also known as cyclooxygenase-2 or COX-2, is an enzyme that in humans is encoded by the ''PTGS2'' gene. In humans it is one of two cyclooxygenases. It is involved in the conversion of arachidonic acid to prostaglandin H2, an important precursor of prostacyclin, which is expressed in inflammation. Function PTGS2 (COX-2), converts arachidonic acid (AA) to prostaglandin endoperoxide H2. PTGSs are targets for NSAIDs and PTGS2 (COX-2) specific inhibitors called coxibs. PTGS-2 is a sequence homodimer. Each monomer of the enzyme has a peroxidase and a PTGS (COX) active site. The PTGS (COX) enzymes catalyze the conversion of arachidonic acid to prostaglandins in two steps. First, hydrogen is abstracted from carbon 13 of arachidonic acid, and then two molecules of oxygen are added by the PTGS2 (COX-2), giving PGG2. Second, PGG2 is reduced to ...

Familial Adenomatous Polyposis
Familial adenomatous polyposis (FAP) is an autosomal dominant inherited condition in which numerous Adenomatous polyps, adenomatous Colorectal polyp, polyps form mainly in the epithelium of the colon (anatomy), large intestine. While these polyps start out benign, malignant transformation into colorectal cancer, colon cancer occurs when they are left untreated. Three variants are known to exist, FAP and attenuated FAP (originally called hereditary flat adenoma syndrome) are caused by APC gene defects on chromosome 5 while autosomal recessive FAP (or MUTYH-associated polyposis) is caused by defects in the ''MUTYH'' gene on chromosome 1. Of the three, FAP itself is the most severe and most common; although for all three, the resulting colonic polyps and cancers are initially confined to the colon wall. Detection and removal before metastasis outside the colon can greatly reduce and in many cases eliminate the spread of cancer. The root cause of FAP is understood to be a genetic mutati ...
