IODOHIPPURATE SODIUM I 131 vs MACROTEC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodohippurate sodium I 131 is a radioactive diagnostic agent that is actively transported by the renal tubules, allowing imaging of renal morphology and function. The iodine-131 emits gamma radiation, enabling scintigraphic evaluation of renal blood flow, tubular secretion, and excretion.
Not applicable for diagnostic use.
Adult: 5-30 microcuries (0.185-1.11 MBq) intravenously for renal function studies.
5 mCi (185 MBq) intravenously as a single dose for lung perfusion imaging.

Terminal elimination half-life is approximately 60 minutes in patients with normal renal function. In renal impairment, half-life may be prolonged up to several hours, correlating with reduced clearance.
6 hours; prolonged in renal impairment (up to 30 hours in ESRD)
Primarily renal; >90% of administered dose excreted unchanged in urine within 24 hours via glomerular filtration and tubular secretion. Fecal excretion <2%.
Renal: 95% as unchanged drug; biliary/fecal: <5% as metabolites
