Web18 nov. 2024 · Iohexol is not bound to serum proteins and is filtered through the glomerulus, with no identifiable reabsorption or tubular secretion, making it an ideal marker for estimating GFR. Unlike other contrast agents such as iothalamate, iohexol has been reported to have a low allergenic potential. WebIn this review, iohexol was found to have a 19.9% rate of contrast-induced nephropathy, whereas iopamidol had a 9.0% contrast-induced nephropathy rate (p = 0.012) . The much higher rate of contrast-induced nephropathy observed for iohexol in this pooled analysis compared with our investigation was likely caused by multiple factors.
