Beschreibung
Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) and COX inhibitor (IC
50s = 0.9-2.7 and 1.5-20 μM, for human COX-1 and COX-2, respectively). It is also an active metabolite of diclofenac methyl ester and diclofenac amide . Diclofenac inhibits release of arachidonic acid (Item Nos.

10006607) induced by A23187 in isolated rat peritoneal neutrophils and macrophages (IC
50s = 60 and 10 μM, respectively). Transdermal administration of diclofenac inhibits carrageenan-induced paw edema in rats. Formulations containing diclofenac have been used in the treatment of pain associated with osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis.

Verwenden
Diclofenac sodium is a nonsteroidal anti-inflammatory compound and cyclooxygenase (COX) inhibitor. Oxidation of diclofenac sodium produces the metabolite 4'-hydroxy diclofenac) which demonstrates specific inhibition of Cox-2. Inhibition of Cox by diclofenac and 4'-hydroxy diclofenac suppresses prostaglandin E2 synthesis, producing anti-inflammatory and analgesic effects. Diclofenac is also shown to stabilize the native tetrameric conformation of transthyretin (TTR) fibrils, preventing the formation of insoluble amyloidogenic TTR deposits. Diclofenac Sodium is a substrate of CYP2C9. It is also used as an inhibitor of Cox-1 and Cox-2.
Definition
ChEBI: Diclofenac sodium is the sodium salt of diclofenac. It contains a diclofenac(1-).
Weltgesundheitsorganisation (WHO)
The World Health Organization currently has no information to
suggest that diclofenac is less safe than other widely available non-steroidal
antiinflammatory substances of this type, or that children are particularly liable to
react adversely. It is registered in many countries in several dosage forms,
including a 12.5 mg suppository indicated for juvenile arthritis.
Allgemeine Beschreibung
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Diclofenac is a derivative of benzeneacetic acid. It is categorized under the class of non-steroidal anti-inflammatory drugs (NSAIDs). It shows inflammatory, analgesic and antipyretic activities.
Clinical Use
Diclofenac sodium is indicated for the treatment of rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis.
Synthese
Synthesis: Acylation of N-phenyl-2,6- dichloroaniline with chloroacetyl chloride gives the corresponding chloroacetanilide, which is fused with aluminum chloride to give 1-(2,6- dichlorophenyl)-2-indolinone. Hydrolysis of the indolinone with dilute aqueous-alcoholic sodium hydroxide affords the desired sodium salt directly.
