CARDIOTEC vs DRAXIMAGE MDP-10
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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).
Technetium-99m medronate is a bone-seeking radiopharmaceutical that localizes in areas of bone turnover, binding via chemisorption to hydroxyapatite crystals, allowing scintigraphic imaging of skeletal lesions.
220-260 MBq (6-7 mCi) intravenously as a single dose for planar or SPECT imaging.
555-1110 MBq (15-30 mCi) intravenously for skeletal imaging; administered 2-3 hours before imaging.

Terminal elimination half-life is 6-8 hours; clinically, steady-state achieved in 24-32 hours
Terminal elimination half-life: 2.5 hours (range 2-3 hours); clinically, allows rapid imaging post-injection.
Renal: 70% as unchanged drug; biliary/fecal: 25% as metabolites; 5% other
Renal: 95% within 6 hours; biliary/fecal: <5%.
