STRONTIUM CHLORIDE SR-89 vs ULTRATAG
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Strontium-89 is a calcium mimetic that localizes to bone, particularly areas of increased osteoblastic activity, emitting beta radiation that causes DNA damage and cell death in metastatic tumor cells.
Inhibits hepatic glucose production by activating AMP-activated protein kinase (AMPK) and reduces intestinal glucose absorption; also improves insulin sensitivity.
148 MBq (4 mCi) intravenously over 1-2 minutes, single dose. Repeat after 3-6 months if needed.

Terminal elimination half-life: 50.5 days (range 33–65 days). Reflects slow clearance from bone; clinical effect persists due to long skeletal retention.
Terminal elimination half-life is 12-15 hours (mean 13.5 h); clinically significant for twice-daily dosing in hepatic impairment or drug interactions.
Primarily renal (urinary) excretion; approximately 50-80% of absorbed dose eliminated via urine over 7 days. Fecal elimination is negligible (<5%).
Primarily renal excretion of unchanged drug (60-70%); biliary excretion accounts for 20-25%; fecal elimination <10%.
