Mechanism of action

Ioversol contains iodine atoms that absorb X-rays more strongly than surrounding soft tissues, creating contrast that allows radiologists to visualize vascular structures, organs, and pathology on X-ray and CT imaging. The non-ionic formulation reduces osmolality compared to ionic contrast agents, which decreases the risk of adverse reactions and renal toxicity. It is administered intravenously and distributes throughout the intravascular and extracellular compartments before being renally eliminated.
