NEPHROSCAN vs TECHNECOLL
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.
TECHNECOLL is a collagen-based hemostatic agent that promotes platelet aggregation and activation of the coagulation cascade, leading to thrombus formation at bleeding sites.
1 to 5 mCi (37 to 185 MBq) as a single intravenous injection for renal imaging.
Intravenous: 250-500 mg every 12 hours; maximum 1 g/day.

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 6.2 hours; clinically, steady-state reached in 24-30 hours
Renal: 95% as unchanged drug via glomerular filtration; no biliary/fecal excretion.
Renal: 95% unchanged; biliary/fecal: 5%
