Product properties


Each ml contains 500 mg metamizole sodium

Mechanism of Action:

Metamizole (dipyrone) is one of the strongest  non-opioid analgesic drugs  with antipyretic and spasmolytic effects. The mechanism responsible for the analgesic effect is a complex one, and most probably rests on the inhibition of a central cyclooxygenase-3 (a splice variant of cox 1 which occurs mainly in the CNS) and activation of the opioidergic system and cannabinoid system. Metamizole can block both PG-dependent and PG-independent pathways of fever induced by LPS, which suggests that this drug has a profile of antipyretic action distinctly different from that of NSAIDs. The mechanism responsible for the spasmolytic effect of metamizole is associated with the inhibited release of intracellular Ca2+ as a result of the reduced synthesis of inositol phosphate. Metamizole derivatives can easily permeate through the blood brain barrier ,their concentration in the cerebrospinal fluid ,is sufficiently high to induce a therapeutic effect. Metamizole is predominantly applied in the therapy of pain of different etiology, of spastic conditions, especially affecting the digestive tract, and of fever refractory to other treatments.
