Dipyrone, also known as Metamizole (INN), is an ampyrone sulfonate analgesic, antispasmodic and antipyretic. It was withdrawn from US market in 1977 on the basis of reports of agranulocytosis. Depyrone is still used to treat severe and diffucult for relieving pains of different origin; headache, tooth-ache, pains in the joints, muscles, following traumas and operations, gall and kidney colics, neurites, neuralgias, traumatic cerebrasthenia; inflammation of upper respiratory ways of microbial or virus origin; chorea; febrile states. Mechanism of action of dipyrone is complex. It is believed that dipyrone exerts its action by inhibiting COX-3, and activates opioid and cannabioid systems either itself, or by products of its metabolic degradation.

Sample Use Guides

Dipyrone was administered orally, as subcutaneous and intramuscular injections (daily dose 0.25-1 g as 50% solution), or by intravenous injection.
Route of Administration: Other
Cyclooxygenase activity was measured by the formation of PGE2 after exposure to exogenous 30 μM acid for 10 min. Dipyrone inhibited COX-1 with IC50 350 uM, and COX-3 with IC50 of 52 uM.
