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.
정의
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

Questionable carcinogen with experimental neoplastigenic data. See also SULFONATES. When heated to decomposition it emits very toxic fumes of NOx,, Na2O, and SOx,.
