IODOHIPPURATE SODIUM I 131 vs XENOVIEW
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.
Xenoview is a paramagnetic contrast agent for MRI that enhances T1 relaxation by shortening the longitudinal relaxation time of water protons in tissues where it accumulates, thereby increasing signal intensity on T1-weighted images.
Adult: 5-30 microcuries (0.185-1.11 MBq) intravenously for renal function studies.
Not applicable (diagnostic agent, not therapeutic); refer to imaging protocol.

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.
Terminal elimination half-life is 3-5 hours in patients with normal renal function; may be prolonged in renal impairment.
Primarily renal; >90% of administered dose excreted unchanged in urine within 24 hours via glomerular filtration and tubular secretion. Fecal excretion <2%.
Primarily renal excretion (60-70% unchanged drug), with 20-25% biliary/fecal elimination.
