INDIUM IN 111 CHLORIDE vs XENOVIEW
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Indium In 111 chloride is a radiopharmaceutical that emits gamma radiation. It binds to transferrin in the blood and is taken up by certain cells, allowing imaging of the reticuloendothelial system or labeled cells.
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.
Intravenous administration of 1.0 mCi (37 MBq) for routine imaging; dose may range from 0.5 to 2.0 mCi (18.5 to 74 MBq) depending on imaging protocol.
Not applicable (diagnostic agent, not therapeutic); refer to imaging protocol.

Physical half-life: 2.804 days (67.3 hours). Biological half-life: 50-100 days for retained fraction. Effective half-life (combined): ~2.7 days for early phase, prolonged for bone marrow.
Terminal elimination half-life is 3-5 hours in patients with normal renal function; may be prolonged in renal impairment.
Renal (90% over 48 hours), fecal (<1% as unchanged). The remainder is retained in organs (liver, spleen, bone marrow) with slow release.
Primarily renal excretion (60-70% unchanged drug), with 20-25% biliary/fecal elimination.
