CHLORMERODRIN HG 197 vs MACROTEC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Radioactive mercury isotope that emits gamma rays; distributes in renal parenchyma, allowing scintigraphic imaging of kidneys. The mercury moiety binds to sulfhydryl groups in renal tubules, concentrating in functioning renal tissue.
Not applicable for diagnostic use.
Chlormerodrin Hg 197 is administered intravenously as a single dose of 10 µCi (0.37 MBq) for renal imaging. The typical adult dose is 10-30 µCi (0.37-1.11 MBq) IV.
5 mCi (185 MBq) intravenously as a single dose for lung perfusion imaging.

Terminal elimination half-life approximately 3 days (72 hours) in patients with normal renal function; prolonged in renal impairment.
6 hours; prolonged in renal impairment (up to 30 hours in ESRD)
Renal: >90% of absorbed dose excreted in urine within 24 hours; biliary/fecal: <5%.
Renal: 95% as unchanged drug; biliary/fecal: <5% as metabolites
