| | Diclofenac Sodium Salt Usage And Synthesis |
| Description |
Diclofenac sodium salt is the sodium salt form of diclofenac, a benzene acetic acid derivate and nonsteroidal anti-inflammatory drug (NSAID) with analgesic, antipyretic and anti-inflammatory activity.
| | Pharmacology | Diclofenac sodium salt is a non-selective reversible and competitive inhibitor of cyclooxygenase (COX), subsequently blocking the conversion of arachidonic acid into prostaglandin precursors. This leads to an inhibition of the formation of prostaglandins that are involved in pain, inflammation and fever.
| | Clinical Use |
Diclofenac sodium salt, like other NSAIDs, is often used as first line therapy for acute and chronic pain and inflammation from a variety of causes. It is often used in combination with misoprostol to prevent NSAID-induced gastric ulcers.
| | Side effects | Gastrointestinal problems (ulceration and bleeding) and adverse CNS reactions (dizziness and headache) are the most commonly encountered adverse effects.
| | 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.
