Due to each of the components of the drug.
Metamizol. When used simultaneously with blockers hl-histamine receptors, butyrophenone and phenothiazine derivatives, tricyclic antidepressants, amantadine and quinidine, m-cholinoblocking action may be enhanced.
Enhances the effects of ethanol. Simultaneous use with chlorpromazine or other phenothiazine derivatives can lead to the development of severe hyperthermia.
Tricyclic antidepressants, oral contraceptives and allopurinol increase the toxicity of the drug.
Phenylbutazone, barbiturates and other inducers of microsomal liver enzymes with simultaneous use reduce the effectiveness of metamizole.
Sedative and anxiolytic drugs (tranquilizers) increase the analgesic effect of metamizole. Radiopaque drugs, colloidal blood substitutes and penicillin should not be used during treatment with drugs containing metamizole.
With the simultaneous use of cyclosporine, the concentration of the latter in the blood decreases.
Metamizole, displacing from the connection with protein oral hypoglycemic drugs, indirect anticoagulants, glucocorticosteroids and indomethacin, can increase the severity of their action.
Thiamazole and cytostatics increase the risk of developing leukopenia.
The effect is enhanced codeine, b2-histamine receptor blockers and propranolol (slows the inactivation of metamizole).
Cherry and currant juice enhances the absorption of metamizole in the gastrointestinal tract (GIT) and promotes an increase in the concentration of its active metabolites in the plasma.
The pitofenon. Strengthens the effect of myotropic antispasmodics (drotaverin, papaverine, mebeverin, otilonium bromide), antisecretory drugs (ranitidine, famotidine).
Fenpierverinium. When combined, increases the hypotensive effect of calcium channel blockers (nifedipine, amlodipine), clonidine and dibazole.
