Metamizole sodium Chemical Properties,Usage,Production

Description

Dipyrone is a water soluble pyrazolone derivative available in oral, rectal and injectable forms. It has analgesic, antipyretic, antispasmodic, and anti-inflammatory properties. Dipyrone is used most commonly to treat severe pain, particularly, for pain associated with smooth muscle spasm or colic affecting the gastrointestinal, biliary or urinary tracts. It is useful for fever that is refractory to other treatment. Because of the risk of serious adverse effects, such as agranulocytosis, its use is justified only in serious situations where no alternative is available or suitable.

Process vivo: Easily absorbed orally, mainly metabolized by the liver and excreted of renal
Indications: It is mainly used for cooling, acute arthritis, headache, rheumatic neuralgia, toothache and muscle pain etc.

Dosage
Oral or intranasal administration. For oral, the adult should take 0.5g of the medicine and three times a day, the amount of the child is 8-10mg/ kg, the number of the times is according to the necessary. For intranasal, the child under 5 years old can take 1-2drops for each nostril, can take the medicine another time if necessary,for the patient above 5 years old increase the dosage appropriately.
Note
1, The dosage should be controled strictly to prevent collapse.
2, The intramuscular injection can cause atrophy and erosion to the local muscle, it is abandoned now.

Chemical Properties

solid

Uses

A non-steroidal anti-inflammatory drug that, when coadministered with morphine, potentiates its antinociceptive action and delays the development of tolerance. Dipyrone is a relatively selective inhibitor of cyclooxygenase-3 (COX-3), with lower activity against COX-1 and no activity against COX-2. Blocks PGE2-induced hyperalgesia in several models.

Uses

Methamizole sodium has expressed analgesic and fever-reducing properties and poorly expressed anti-inflammatory action, and is very convenient in cases where high concentrations of drug need to be quickly reached. Methamizole sodium is used for relieving pain of various origins (renal and biliary colic, neuralgia, myalgia, trauma, burns, headaches, and toothaches). Use of this drug may cause allergic reactions, and long-term use may cause granulocytopenia.

Definition

ChEBI: An organic sodium salt of antipyrine substituted at C-4 by a methyl(sulfonatomethyl)amino group, commonly used as a powerful analgesic and antipyretic.

World Health Organization (WHO)

Metamizole sodium, a pyrazolone derivative with analgesic, antipyretic and antinflammatory activity, was introduced in 1921 and has since been widely available in over-the-counter products. By the early 1970s its use had been associated, as with some other pyrazolones, with serious and sometimes fatal adverse reactions, notably cases of blood dyscrasias including agranulocytosis, which led to its withdrawal by some regulatory authorities. Although preparations of metamirole sodium are prohibited in certain countries, they remain widely available in others and, in some cases, in over-the-counter products.

Safety Profile

Poison by subcutaneous route. Moderately toxic by several other routes. An experimental teratogen. Other experimental reproductive effects. Human mutation data reported. Questionable carcinogen with experimental neoplastigenic data. See also SULFONATES. When heated to decomposition it emits very toxic fumes of NOx,, Na2O, and SOx,.

Synthesis

Methamizole sodium, 1-phenyl-2,3-dimethyl-4-methylaminopyrazolone-5-N-sodium methansulfonate (3.2.16), is synthesized in a multi-stage synthesis from acetoacetic ester and phenylhydrazine. Their reaction leads to the formation of 1-phenyl- 3-methylpyrazolone-5 (3.2.9). Methylation of this product with methyl iodide gives 1-phenyl- 2,3-dimethylpyrazolone-5 (3.2.10). This compound is used independently in medicine as a fever-reducing and anti-inflammatory analgesic under the name antipyrin. It undergoes nitrozation by sodium nitrite in an acidic medium, forming 1-phenyl-2,3-dimethyl-4- nitrozopyrazolone-5 (3.2.11). Reduction of the nitrous derivative (3.2.11) by different reducing agents leads to the formation of 1-phenyl-2,3-dimethyl-4-aminopyrazolone-5 (3.2.12). This product is reacted with benzaldehyde, forming an easily separable crystalline 1-phenyl- 2,3-dimethyl-4-benzylidenaminopyrazolone-5 (3.2.13), which is methylated at the imine atom of nitrogen by dimethylsulfate, giving a quaternary salt (3.2.14). Hydrolysis of the resulting salt gives 1-phenyl-2,3-dimethyl-4-methylaminopyrazolone-5 (3.2.15). Treating the product with a water solution of a mixture of sodium bisulfite and formaldehyde leads to the formation of 1-phenyl-2,3-dimethyl-4-methylaminopyrazolone-5-N-sodium methanesulfonate (3.2.16), the desired sodium methamizole [72¨C75].
