This book was released on 2012-12-06 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1971, Vane proposed that the mechanism of action of the aspirin-like drugs was through their inhibition of prostaglandin biosynthesis. Since then, there has been intense interest in the interaction between this diverse group of inhibitors and the enzyme known as cyclooxygenase (COX). It exists in two isoforms, COX-l and COX-2 (discovered some 5 years ago). Over the last two decades several new drugs have reached the market based on COX-l enzyme screens. Elucidation of the three-dimensional structure of COX-l has provided a new understanding for the actions of COX inhibitors. The constitutive isoform of COX, COX-l has clear physiological functions. Its activation leads, for instance, to the production of prostacyclin which when released by the endothelium is anti-thrombogenic and anti-atherosclerotic, and in the gastric mucosa is cyto protective. COX-l also generates prostaglandins in the kidney, where they help to maintain blood flow and promote natriuresis. The inducible isoform, COX-2, was discovered through its activity being increased in a number of cells by pro inflammatory stimuli. A year or so later, COX-2 was identified as a distinct isoform encoded by a different gene from COX-I. COX-2 is induced by inflammatory stimuli and by cytokines in migratory and other cells. Thus the anti-inflammatory actions of non-steroid anti-inflammatory drugs (NSAIDs) may be due to the inhibition of COX-2, whereas the unwanted side-effects such as irritation of the stomach lining and toxic effects on the kidney are due to inhibition of the constitutive enzyme, COX-I.

Available in PDF, EPUB and Kindle. Book excerpt: The mainstay of therapy for rheumatoid disease is the non-steroid antiinflammatory drugs (NSAIDs), despite their inherent gastrointestinal toxicity and ability to cause renal damage in susceptible patients. The theory that the beneficial and toxic effects of NSAIDs stem from a reduction in prostanoid production through inhibition of cyclooxygenase implied that particular toxicities were inevitable with NSAIDs and would always be correlated with efficacy. However, over the years, it became apparent that at therapeutic doses, some NSAIDs had greater toxic side-effects than others, a fact not explained by the general theory. A significant clarification arose from the discovery that there are two distinct isoforms of COX, a constitutive enzyme (COX-I) responsible for the production of prostanoids necessary for platelet aggregation and protection of the gastric mucosa and kidney; and an inducible enzyme (COX-2) that is newly synthesized at sites of tissue damage and produces prostaglandins that manifest pathological effects. It became clear that different NSAIDs had greater or lesser effects on COX-I when used in therapeutic doses, explaining the variation in side-effects. ' The elucidation of the crystal structure of these different enzymes and the skills of medicinal chemists have led to the synthesis of new chemicals with a selectivity for the inducible enzyme, and thus with therapeutic efficacy without those toxic effects result ing from inhibition of the constitutive enzyme.
Download or read book New Targets in Inflammation written by N. Bazan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past 100 years the mainstay of therapy for rheumatoid arthritis (RA) has been aspirin or other drugs of the non-steroid anti-inflammatory group. In 1971 Vane pro posed that both the beneficial and toxic actions of these drugs was through inhibition of prostaglandin synthesis. The recent discovery that prostaglandins responsible for pain and other symptoms at inflammatory foci are synthesized by an inducible cyclooxygenase (COX-2) that is encoded by a gene distinct from that of the consti tutive enzyme (COX-I) provided a new target for therapy of RA. A drug that would selectively inhibit COX-2 would hopefully produce the symptomatic benefit provided by existing NSAIDs without the gastrointestinal and renal toxicity due to the inhibition of COX-I. Drugs selective for COX-2 are now available. Experimental studies have shown them to be effective with minimal toxicity, and in clinical trials gastric and renal toxicities are less. Highly selective COX-2 inhibitors, perhaps designed with knowledge of the crystal structures of COX-I and COX-2, are also available. Other experimental studies, including those in animals lacking effective genes for COX-lor COX-2 and in experimental carcinomas, suggest there is still much to be learned of the pathophysiological functions of these enzymes. The inflammatory response is a complex reaction involving many mediators that derive from white blood cells, endothelial cells and other tissues. Preliminary data have revealed that inhibitors of the cytokines and adhesion molecules that play a crucial role in the migration of white cells to inflammatory sites may be useful in RA.

Download or read book Trends in COX 2 Inhibitor Research written by Maynard J. Howardell and published by Nova Publishers. This book was released on 2006 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cox-2 Inhibitors are newly developed drugs for inflammation that selectively block the Cox-2 enzyme. Blocking this enzyme impedes the production of the chemical messengers (prostaglandins) that cause the pain and swelling of arthritis inflammation. Cox-2 inhibitors are a new class of non-steroidal anti-inflammatory drugs (NSAIDS). Because they selectively block the Cox-2 enzyme and not the Cox-1 enzyme, these drugs are uniquely different from traditional NSAIDS. This book explores new research in the field.

Download or read book Advances in Modelling and Clinical Application of Intravenous Anaesthesia written by J. Vuyk and published by Springer Science & Business Media. This book was released on 2003-02-28 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its launch in 1998 the European Society for Intravenous Anaesthesia (EuroSIVA) has come a long way in providing educational material and supporting the research and clinical application of intravenous anaesthesia. After the first two annual meetings held in Barcelona and Amsterdam in 1998 and 1999, three other successful meetings took place in Vienna, Gothenburg and Nice in 2000, 2001 and 2002. Next to these main meetings, starting in the year 2000, a smaller winter meeting has been organised every last week of January in Crans Montana, Switzerland. Both the main summer and the winter meetings breathe the same atmosphere of sharing the latest on intravenous anaesthesia research in the presence of a friendly environment and good company. Since the first meetings the educational tools of EuroSIVA have increased in quantity and technical quality allowing digital slide and video presentation along with the use of the computer simulation program TIVAtrainer during the speaker sessions and the workshops. Furthermore, EuroSIVA now exploits a website www. eurosiva. org that allows for continuous exchange of information on intravenous anaesthesia, the TIVAtrainer, the EuroSIVA meetings and online registration for these meetings. The EuroSIVA is currently engaged in friendly contacts with the Asian Oceanic Society for Intravenous Anaesthesia (AOSIVA), the United Kingdom Society for Intravenous Anaesthesia (UKSIVA), the Korean Society for Intravenous Anaesthesia (KSIVA), the European Society of Anaesthesiology (ESA) and the International Society for Applied Pharmacology (ISAP).

Download or read book Drug Class Review on Cyclo oxygenase COX 2 Inhibitors and Non steroidal Anti inflammatory Drugs NSAIDs written by Roger Chou and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-steroidal anti-inflammatory drugs (NSAIDs) reduce pain and inflammation by blocking cyclo-oxygenases (COX), enzymes that are needed to produce prostaglandins. Most NSAIDs block two different cyclo-oxygenases, called COX-1 and COX-2. COX-2, found in joint and muscle tissue, contributes to pain and inflammation. Many NSAIDs also block COX-1, which may contribute to development of ulcers and gastrointestinal bleeding depending on the magnitude of blockade. More recently, some NSAIDs have also been associated with an increased risk of serious cardiovascular events, such as myocardial infarction. The purpose of this review is to compare the efficacy, effectiveness, and harms of NSAIDs.
