The vascular effects of COX-2 selective inhibitors
The discovery of the two isoforms of COX (COX-1 and COX-2) has led to greater understanding of the mechanism of action and potential adverse effects of NSAIDs.... Introduction Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely used of therapeutic agents. Taken singly or in combination with other classes of drug, they relieve symptoms

COX-dependent mechanisms involved in the antinociceptive

Inhibition of COX-2 activity represents the most likely mechanism of action for NSAID-mediated analgesia, while the ratio of inhibition of COX-1 to COX-2 by NSAIDs should determine the likelihood of adverse effects. In addition, some NSAIDs inhibit the lipoxygenase pathway, which may itself result in the production of algogenic metabolites. Interference with G-protein-mediated signal...
The NSAIDs aspirin, indomethacin and ibuprofen are nonselective inhibitors of COX isozymes whereas celecoxib and rofecoxib exhibit selective COX-2 inhibition. Arachidonic acid …

3/09/2013 · Mechanisms of Action of NSAIDs in CRC Chemoprevention Aspirin and NSAIDs have regulatory effects on the gene transcription and protein synthesis of multiple molecules involved in several inflammatory and neoplastic pathways [ 12 ].

  • Cyclooxygenase and NSAIDs. Cyclooxygenase • An enzyme responsible for the production of prostaglandins • Two forms, COX1 and COX2 • Contains two separate active sites for prostaglandin synthase • One side contains the cyclooxygenase active site • The opposite side contains the peroxidase active site which is involved in activating the heme group necessary for cyclooxygenase …
  • Classes of Nsaids are based on their chemical structure or mechanism of action. Older NSAIDs were known long before their mechanism of action was elucidated and were for this reason classified by chemical structure or origin.
  • These is increasing evidence that NSAIDs have a central mechanism of action that augments the peripheral mechanism. This effect may be the result of interference with the formation of prostaglandins within the CNS. Alternatively, the central action may be mediated by endogenous opioid peptides or blockade of the release of serotonin (5-hydroxytryptamine; 5-HT). A mechanism involving inhibition
