Selective COX-2 inhibitors have antiinflammatory actions similar to conventional nonselective NSAIDs, but there is some evidence that they may be less effective analgesics. Selective COX-2 inhibitors do not affect platelet TXA 2 production and therefore do not directly impair platelet aggregation. These newer drugs were termed COX-2 selective NSAIDs and also referred to as COX-2 inhibitors, selective COX-2 inhibitors, and coxibs. An overview of the COX-2 selective NSAIDs, particularly of those characteristics that distinguish them from COX nonselective NSAIDs, is presented here.
There have been several clinical trials of selective COX-2 inhibitor for HO control in THA. However, the effectiveness of the use of selective COX-2 inhibitors in THA patients was controversial in several studies. And whether selective COX-2 inhibitor was as effective as non-selective COX inhibitor . Exacerbation with a range of COX-2 selective inhibitors in experimental colonic inflammation has been reported,64 and such agents do not appear to offer anti-inflammatory benefit in colitic models However, the possibility that selective COX-2 inhibitors could also have a use in other major therapeutic areas such as in colon cancer, as well Cited by:
Less than 10 years after the discovery of the COX-2 gene, 2 different selective COX-2 inhibitors were approved for human use and several others are currently under investigation. This book provides a timely review of the history and current status of work with this important new class of by: 1. These agents are used for prophylaxis in high-risk patients. The place of this strategy in comparison with COX-2 inhibitors is difficult to predict and may depend on relative pricing. Compared with COX-2 inhibitors, NSAIDs with a protective agent will allow the benefits of selective COX-1 and COX-2 inhibition to be by:

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 Format: Paperback.

The development of selective COX-2 inhibitors started in early ’s with the identification of COX-2 isoenzyme which was found to be responsible for the pathological processes such as inflammation and pain.
Thus, it was though that more selective COX-2 inhibitors would have reduced the side by: COX-2 Selective (includes Bextra, Celebrex, and Vioxx) and Non-Selective Steroidal Anti-Inflammatory Drugs (NSAIDs); U.S. Food and Drug Administration Overview of selective COX-2 inhibitors.
COX-2 inhibitors may also delay the ability of the blood to clot, increasing the risk of hemorrhage. COX-2 inhibitors are not approved for use in children younger than two years old.
Most NSAIDs, including celecoxib, should not be taken during the last three months of pregnancy or while breastfeeding except on a doctor’s advice.
The COX-2 inhibitors represent a newer class of anti-inflammatory drugs that do not affect COX-1, but selectively block only COX This selective action provides the benefits of reducing inflammation without the increased risk of stomach irritation, ulceration, and bleeding.

COX-2 inhibitors and other NSAIDs may increase the risk of heart attacks, stroke, and related conditions, which can be fatal.
This risk may increase with duration of use and in patients who have underlying risk factors for disease of the heart and blood vessels. The introduction of celecoxib (Celebrex) and rofecoxib (Viox), COX-2 selective inhibitors was effected to decrease the adverse effects that are typically associated with inhibition of COX The recent concerns about the safety of COX-2 selective inhibitors pertain to a possible increase in the risk of cardiovascular events such as myocardial 4/5(2).
These side effects led in time to the development of NSAIDs that behave as selective COX-2 inhibitors. This manuscript highlights the structure–activity relationships which characterize the chemical scaffolds endowed with selective COX-2 inhibition.
Additionally, the role of COX-2 inhibitors in the pain phenomenon and cancer is discussed. Molecular Modelling Studies of Novel COX-2 Inhibitors: /ch Molecular modelling uses theoretical and computational chemistry, which offers insight into the nature of molecular systems.

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.

Assessment of COX-2 selectivity There is a wide variety of assays to assess COX-1 and COX-2 selectivity. 4 This has led to confusion in the reporting of the relative effects of some of the new selective inhibitors depending on which assay system is used.

The term selective cox-2 inhibitors refer to the drugs which will block only the cox-2 isoenzyme. On the other hand nonselective and preferential cox inhibitors will block both cox-1 and cox Selective cox-2 ones will have lesser side effects as compared to non selective inhibitors because it will supress the regulation of prostaglandins and lead to hepatic and renal side effects.
Methods. We conducted a case control study of breast cancer designed to compare effects of selective and non-selective COX-2 inhibitors. A total of incident breast cancer patients were ascertained from the James Cancer Hospital, Columbus, Ohio, during – and compared with cancer free controls matched to the cases at a ratio on age, race, and county of by:
