CONTRAST GADOLINIUM COMPLEX COMPOSITION FOR MEDICAL DIAGNOSTICS Russian patent published in 2010 - IPC A61K49/00 A61K49/12

Abstract RU 2396983 C1

FIELD: medicine.

SUBSTANCE: invention refers to a contrast composition in the form of an aqueous solution for magnetic-resonance and X-ray diagnostics containing gadolinium oxide (Cd₂O₃), diethylene triaminopentaacetic acid (DTPA), medical polymer - polyvinylpyrrolidone of molar mass (12000±5000) Da in amount 0.5-5 wt % and pH 5.0-8.5.

EFFECT: invention provides preparation of the composition with the lower content of free gadolinium ensured by DTPA/Cd₂O₃concentrations related as 2,035-2,10 that exceeds the stoichiometric ratio.
