The Mechanisms of Action of NSAIDs in Analgesia | SpringerLink

Trends Pharmacol Sci ; J Clin Invest ; Traditionally, the analgesic action of nonsteroidal anti-inflammatory drugs NSAIDs has been explained on the basis of their inhibition of the enzymes that synthesise prostaglandins. Alternatively, the central action may be mediated by endogenous opioid peptides or blockade of the release of serotonin 5-hydroxytryptamine; 5-HT.

Dissociation between the antinociceptive and anti-inflammatory effects of nonsteroidal anti-inflammatory drugs: Effects of peripherally and centrally acting analgesics on somatosensory evoked potentials.

Molecular cloning of human prostaglandin endoperoxide synthase type II and demonstration of expression in mechanism of action of nsaids pdf download to cytokines. Inhibition of prostaglandin synthesis as a mechanism of action for aspirin-like drugs.

Peripheral mechanisms of somatic pain. COX-2, discovered 6 years ago, is induced by inflammatory stimuli and cytokines in migratory and other cells. Interactions between substance P, calcitonin gene-related peptide, taurine and excitatory amino acids in the spinal cord.

The Mechanisms of Action of NSAIDs in Analgesia

However, mschanism is clear that NSAIDs exert their analgesic effect not only through peripheral inhibition of prostaglandin synthesis but also through a variety of other peripheral and central mechanisms. Fatty acid cyclo-oxygenase inhibitors and the regulation of cerebral blood flow.

Inflammatory mediators of pain. Br J Pharmacol ; Inhibitory effects of diclofenac and indomethacin on interleukininduced changes in PGE2 release. COX-1 activity ratio will have a potent anti-inflammatory activity nszids fewer side-effects than drugs with a less favorable COX The mechanism of action of aspirin. Salicylic acid and salicylates, obtained from natural sources, mechanism of action of nsaids pdf download long been used as medicaments. It is therefore attractive to suggest that the anti-inflammatory actions of NSAIDs are due to inhibition of COX-2, whereas the unwanted snaids, such as irritation of the stomach lining, are due to inhibition of COX Pharmacokinetics of aspirin and salicylate in relation to inhibition of arachidonate cyclooxygenase and antiinflammatory activity.

The identification of selective inhibitors of COX-2 will therefore lead to advances in therapy. Dray A, Bevan S. Check if you have access through your login credentials or your institution.
