MACROTEC vs TECHNETIUM TC-99M MEDRONATE KIT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Not applicable for diagnostic use.
Technetium Tc-99m medronate (MDP) is a bone-seeking radiopharmaceutical that binds to calcium ions in hydroxyapatite crystals of bone. Uptake is proportional to osteoblastic activity and regional blood flow, allowing scintigraphic imaging of skeletal structures.
5 mCi (185 MBq) intravenously as a single dose for lung perfusion imaging.
Intravenous injection: 370-1110 MBq (10-30 mCi) for bone imaging. Adult dose is administered once for each imaging procedure.

6 hours; prolonged in renal impairment (up to 30 hours in ESRD)
Terminal elimination half-life: 6.02 hours (range 5.8–6.3 hours) in patients with normal renal function; prolonged in renal impairment.
Renal: 95% as unchanged drug; biliary/fecal: <5% as metabolites
Renal: approximately 50% of injected dose excreted unchanged in urine within 24 hours. Biliary/fecal: less than 5%.
