DRAXIMAGE DTPA vs TECHNECOLL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DRAXIMAGE DTPA (technetium Tc-99m pentetate) is a radiopharmaceutical that, after intravenous injection, distributes in the extracellular space and is cleared by glomerular filtration. It allows imaging of renal function and structure by emitting gamma radiation detectable by a gamma camera.
TECHNECOLL is a collagen-based hemostatic agent that promotes platelet aggregation and activation of the coagulation cascade, leading to thrombus formation at bleeding sites.
Diagnostic imaging: 3-5 mCi (111-185 MBq) IV for renal studies; 10-20 mCi (370-740 MBq) IV for lung perfusion imaging.
Intravenous: 250-500 mg every 12 hours; maximum 1 g/day.

Terminal elimination half-life is approximately 1.6 hours (range 1.2-2.0 hours) in patients with normal renal function; prolonged in renal impairment (up to 50 hours in severe cases).
Terminal elimination half-life 6.2 hours; clinically, steady-state reached in 24-30 hours
Renal: 95% within 24 hours via glomerular filtration; biliary/fecal: <5%.
Renal: 95% unchanged; biliary/fecal: 5%
