Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Stannous diphosphonate is a radiopharmaceutical agent that forms a complex with technetium-99m; it localizes to areas of increased bone turnover by chemisorption to hydroxyapatite crystals, thereby enabling bone scintigraphy.
PULMOLITE is a leukotriene receptor antagonist (LTRA) that selectively and competitively inhibits the cysteinyl leukotriene (CysLT1) receptor in the human airway, thereby reducing bronchoconstriction, mucus secretion, and eosinophilic infiltration.
Adult: 1-4 mg administered intravenously, single dose for bone scintigraphy.
Adults: 200 mg intravenously every 12 hours over 30 minutes.

Terminal elimination half-life: Approximately 2.5 hours for the diphosphonate component; the stannous ion is cleared more slowly. Clinically, this allows rapid bone uptake and background clearance for imaging within 2–4 hours post-injection.
Terminal elimination half-life: 12 hours (range 10–14 h) in adults with normal renal function (CrCl >90 mL/min); prolonged to 24–30 h in severe renal impairment (CrCl <30 mL/min).
Renal: >90% of the administered dose is excreted unchanged in the urine within 24 hours. Biliary/fecal: Minimal (<2%).
Primarily renal (80%) as unchanged drug; 15% fecal via biliary excretion; 5% metabolized.
