iopromide - Generic Medications

ULTRAVIST (iopromide) injection is a nonionic radiographic contrast agent for intra-arterial or intravenous administration. The chemical name for iopromide is N,N' -Bis(2,3-dihydroxypropyl)-2,4,6-triiodo-5-[(methoxyacetyl)amino]- N -methyl- 1,3- benzenedicarboxamide. Iopromide has a molecular weight of 791.12 (iodine content 48.12%). Iopromide has the following structural formula: Each mL contains 623.4 mg or 768.86 mg iopromide (300 mg or 370 mg iodine, respectively) and the following inactive ingredients: 0.1 mg edetate calcium disodium as a stabilizer and 2.42 mg tromethamine as a buffer. It may also contain sodium hydroxide or hydrochloric acid to adjust pH to 7.4 (6.5–8) at 25± 2°C and contains no preservatives. ULTRAVIST is a sterile (sterilized by autoclaving), clear, colorless to slightly yellow, odorless, pyrogen-free aqueous solution and has the following physicochemical properties: Property Concentration of ULTRAVIST (mg Iodine/mL) 300 370 Osmolality*(mOsmol/kg water) @ 37°C 607 774 Osmolarity*(mOsmol/L) @ 37°C 428 496 Viscosity (cP) @ 20°C @ 37°C 9.2 4.9 22 10 Density (g/mL) @ 20°C @ 37°C 1.330 1.322 1.409 1.399 *Osmolality was measured by vapor-pressure osmometry. Osmolarity was calculated from the measured osmolal concentrations. ULTRAVIST 300 mg Iodine per mL and 370 mg Iodine per mL have osmolalities respectively 2.1 and 2.7 times that of plasma (285 mOsmol/kg water). Chemical diagram
