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.
SETHOTOPE is a radiolabeled monoclonal antibody that binds to the prostate-specific membrane antigen (PSMA) on prostate cancer cells, delivering beta radiation (177Lu) to cause DNA damage and cell death.
Intravenous administration of 10-20 mCi (370-740 MBq) for adult bone imaging. Administer 2-4 hours prior to imaging.
1.0 mg IV every 12 hours for 7 days.

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: 12 hours (range 10-14 h); clinically, dosing interval is 12-24 h to maintain therapeutic levels
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; fecal: 25% as metabolites; biliary: 5%
