Webideal markers—such as iohexol, iothalamate, iopamidol, and iopromide—have been proposed as alternatives for measuring GFR. Iohexol is the most widely used marker for measuring GFR, at least in Europe, and is increasingly being used in other countries, while iothalamate is traditionally the most widely used marker in the Unites States. The ... Web(1) A recommendation from the conference is that in drug development, GFR should be measured directly with an inert tracer (e.g. inulin, iohexol, iothalamate, etc.) to determine pharmacokinetic or pharmacodynamic alterations due …

Previous studies have noted possible differences in renal handling of these 2 agents, but clarity about the differences has been lacking. Study Design Study of diagnostic test accuracy. Webiothalamate and iohexol, have therefore been more widely used. Several studies have suggested that iothalamate1-6 and iohexol7 provide renal clearance measures that are …

WebEstimated GFR Notes Glomerular filtration rate can only be determined accurately by direct measurement of renal clearance of markers such as inulin, 51 Cr-EDTA, 125 I-iothalamate or iohexol, but GFR can be estimated from serum creatinine using a number of formulae. WebInjection of iothalamate led to large extravasation of 99 Tc m-DTPA, 125 I-HSA and Trypan blue which means severe damage of the blood-brain barrier. Injection of iopentol and iohexol resulted in some extravasation of all three tracers used, whereas injection of iodixanol only led to extravasation of the small molecule tracer 99 Tc m -DTPA …
