DRAXIMAGE MDP-10 vs TECHNESCAN HDP
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 areas of bone turnover, binding via chemisorption to hydroxyapatite crystals, allowing scintigraphic imaging of skeletal lesions.
Technetium Tc-99m oxidronate (HDP) is a bone-seeking radiopharmaceutical that localizes to areas of osteoblastic activity. It binds to hydroxyapatite crystals in bone via chemisorption, allowing scintigraphic imaging of skeletal lesions.
555-1110 MBq (15-30 mCi) intravenously for skeletal imaging; administered 2-3 hours before imaging.
For bone scintigraphy: 740 MBq (20 mCi) intravenous injection.

Terminal elimination half-life: 2.5 hours (range 2-3 hours); clinically, allows rapid imaging post-injection.
Terminal elimination half-life is approximately 2-3 hours for the diphosphonate component, with clinical imaging typically performed 2-4 hours post-injection.
Renal: 95% within 6 hours; biliary/fecal: <5%.
Renal: >95% excreted unchanged in urine within 24 hours. Biliary/fecal: <5%.
