Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Technetium-99m medronate is a bone-seeking radiopharmaceutical that localizes in bone by chemisorption to hydroxyapatite crystals, particularly in areas of increased osteoblastic activity.
CARDIOTEC is a technetium-99m labeled tracer that binds to viable myocardial cells. Its uptake is dependent on mitochondrial membrane potential and reflects myocardial perfusion and viability. The exact mechanism involves passive diffusion across cell membranes and retention within mitochondria via interaction with the mitochondrial complex I (NADH dehydrogenase).
Intravenous administration of 10-20 mCi (370-740 MBq) for adult bone imaging. Administer 2-4 hours prior to imaging.
220-260 MBq (6-7 mCi) intravenously as a single dose for planar or SPECT imaging.

Terminal elimination half-life: approximately 6 hours (range 4-8 hours) for the diphosphonate component; reflects clearance from bone and renal elimination.
Terminal elimination half-life is 6-8 hours; clinically, steady-state achieved in 24-32 hours
Renal: approximately 50-60% unchanged within 2-3 hours post-injection; biliary/fecal: negligible (<5%). The remainder is retained in bone (up to 40%) with slow release.
Renal: 70% as unchanged drug; biliary/fecal: 25% as metabolites; 5% other
