Which type of contrast media is associated with ionic characteristics?

High-osmolar contrast media (HOCM) is associated with ionic characteristics. This type of contrast media contains molecules that dissociate into ions in solution, leading to a higher osmolality compared to blood plasma. The ionic nature contributes to the increased risk of adverse reactions and side effects, such as allergic responses and nephrotoxicity, especially in patients with pre-existing conditions affecting the kidneys.

Furthermore, the properties of high-osmolar contrast media often necessitate careful consideration when administering to patients due to these potential complications. In contrast, low-osmolar and iso-osmolar contrast media are designed to be less reactive and are generally better tolerated. Nonionic contrast agents also do not dissociate into ions, further reducing the risk of complications associated with ionic characteristics.
