Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that reduces fever, pain and inflammation. Indomethacin works by reducing the production of prostaglandins. Prostaglandins are chemicals that the body uses to cause fever, pain and inflammation. Indomethacin blocks the enzymes that make prostaglandins (cyclooxygenase 1 and 2) and thereby reduces the levels of prostaglandins. As a result, fever, pain and inflammation are reduced.

Indometacin (INN) or Indomethacin (USAN and former BAN) is a non-steroidal anti-inflammatory drug commonly used to reduce fever, pain, stiffness, and swelling. It works by inhibiting the production of prostaglandins, molecules known to cause these symptoms. It is marketed under many trade names, including Indocin, Indocid, Indochron E-R, and Indocin-SR.

Indomethacin does have potential side effects.... By reducing cerebral blood flow, indomethacin may increase the risk of cerebral hypoxia [Edwards 1990]. It remains essential, therefore, to assess carefully long-term neurodevelopmental outcomes since this potential adverse effect may oppose any benefit of a possible reduction in the incidence of intraventricular haemorrhage. Similarly, although closure of the patent ductus may be expected to reduce the incidence of necrotizing enterocolitis, this needs to be balanced against any effect indomethacin might have directly on gut blood flow [Coombs 1990]. Indomethacin may also reduce renal blood flow, thus impairing renal function [Cifuentes 1979]. In addition, it may interfere with platelet aggregation, thus impairing haemostasis [Friedman 1978].

Indomethacin has other potential actions in eosinophils, most notably through its anti-inflammatory ability to inhibit COX-1 and COX-2 isoenzymes (Fig. 9). Published IC50 values for indomethacin on these enzymes vary within low to high nanomolar ranges (56-59), and ... inhibition of eosinophil COX isoenzymes within the experiments here may have occurred. However, no other NSAID from an extensive panel of drugs including nonselective NSAIDs and drugs with specific actions on either COX-1 or COX-2, tested across a broad range of concentrations, induced any similar responses in human eosinophils. These data, in combination with the observed similarities in signaling between PGD2 and indomethacin in this study and the identification of indomethacin as a ligand for the eosinophil-expressed PGD2 receptor, CRTH2 (36), strongly suggest that the proinflammatory actions of indomethacin on eosinophils and basophils are not mediated by COX inhibition.

Indomethacin (Sigma, Poole, UK) and the selective COX-2 inhibitor, NS-398 (Cayman Chemical, Ann Arbor, MI) were prepared as 100 mM stock solutions in dimethyl sulphoxide (DMSO) obtained from Sigma. Control flasks or plates contained DMSO at an equivalent dilution to that in cultures containing NSAIDs. Lactacystin (Affiniti, Exeter, UK) was prepared as a 3 mM stock solution in sterile, distilled water. Mouse monoclonal anti-human ß-catenin antibodies 6F9 and C19220 were obtained from Sigma and BD Transduction Laboratories (Lexington, KT), respectively. Mouse monoclonal anti-human -catenin antibody (C26220) was obtained from Transduction Laboratories. Mouse monoclonal anti-human ß-actin antibody (AC-15) was obtained from Sigma.

Indomethacin inhibits prostaglandins, which reduces renin and aldosterone, and, in turn, reduces potassium excretion and causes hyperkalemia. nutritional. Indomethacin belongs to the class of medications known as nonsteroidal anti-inflammatories (NSAIDs). It works by reducing pain, swelling, and inflammation. China null of Indomethacin.
