NEPHROSCAN vs TECHNETIUM TC 99M MERTIATIDE KIT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcium trisodium pentetate (NEPHROSCAN) chelates gadolinium ions by forming a stable complex with the metal, thereby reducing the toxicity and enhancing elimination of gadolinium from the body. It acts as a decorporation agent for gadolinium.
Technetium Tc 99m mertiatide is a radiopharmaceutical diagnostic agent that undergoes renal tubular secretion and glomerular filtration, allowing for dynamic imaging of renal function and urinary tract patency.
1 to 5 mCi (37 to 185 MBq) as a single intravenous injection for renal imaging.
1-10 mCi (37-370 MBq) intravenously as a single dose for renal imaging.

Terminal elimination half-life: 1.6 hours in normal renal function; prolonged to >20 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life: approximately 1.5–2 hours for the non-protein-bound fraction; allows rapid imaging within 30 minutes and clearance from blood pool.
Renal: 95% as unchanged drug via glomerular filtration; no biliary/fecal excretion.
Renal: approximately 50% excreted unchanged in urine within 2 hours; 70% within 24 hours. Biliary/fecal: negligible.
