DRAXIMAGE MDP-25 vs RADIOGENIX SYSTEM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Technetium-99m methylene diphosphonate (MDP) is a bone-seeking radiopharmaceutical. After intravenous injection, it adsorbs onto hydroxyapatite crystals in bone, with increased uptake in areas of high metabolic activity or blood flow, such as tumors or fractures. The technetium-99m emits gamma rays which are detected by a gamma camera for imaging.
RADIOGENIX SYSTEM is a radiopharmaceutical that emits beta radiation (yttrium-90 microspheres) to deliver targeted radiotherapy to hepatic tumors via intra-arterial administration, causing irreversible DNA damage and cell death.
555–925 MBq (15–25 mCi) intravenously for bone scintigraphy; imaging performed 2–4 hours post-injection
Not applicable; the RADIOGENIX SYSTEM is a medical imaging device, not a pharmacologic agent. No standard dosing.

Terminal elimination half-life is approximately 6-8 hours for the primary complex; minor radiochemical impurities may have longer half-lives
Physical half-life of 6.0 hours for Tc-99m; effective half-life is approximately 6.0 hours due to rapid renal clearance.
Primarily renal (urinary excretion of 60-70% as unchanged drug within 24 hours, with 5-10% biliary excretion)
Primarily renal excretion; >95% of administered activity excreted in urine within 24 hours; negligible biliary or fecal elimination.
