Iohexol

Description:
Iohexol is a non-ionic, water-soluble contrast agent commonly used in medical imaging, particularly in computed tomography (CT) scans and angiography. It belongs to the class of iodinated contrast media, which enhances the visibility of internal structures in radiographic imaging. Iohexol has a molecular formula that includes iodine, which is responsible for its radiopacity, allowing it to absorb X-rays effectively. The substance is characterized by its low osmolality, which reduces the risk of adverse reactions compared to older, high-osmolality contrast agents. It is typically administered intravenously and is known for its relatively low toxicity profile. Iohexol is stable under normal conditions and is excreted primarily through the kidneys, making it suitable for patients with normal renal function. However, caution is advised in individuals with renal impairment or those at risk of contrast-induced nephropathy. Overall, Iohexol is a widely used and effective agent in diagnostic imaging, facilitating clearer visualization of anatomical structures and pathological conditions.
