AREDIA vs EXDENSUR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bisphosphonate that inhibits osteoclast-mediated bone resorption by binding to hydroxyapatite crystals in bone and inhibiting osteoclast activity.
EXDENSUR (generic name not specified) is a novel oral anticoagulant that selectively inhibits activated factor XI (FXIa), thereby reducing thrombin generation and preventing clot formation without significantly affecting hemostasis.
90 mg intravenously over 2 hours every 3-4 weeks for hypercalcemia of malignancy; 90 mg intravenously over 2 hours every 4 weeks for osteolytic bone metastases of breast cancer or multiple myeloma.
5 mg orally twice daily

Multiphasic; terminal half-life is approximately 300 hours (range 200-400 hours) reflecting slow release from bone. Clinically, this results in prolonged suppression of bone resorption lasting weeks after a single dose.
Terminal elimination half-life is 8 hours in healthy adults, prolonged to 12-15 hours in moderate renal impairment (CrCl 30-50 mL/min).
Primarily eliminated unchanged via renal excretion (about 30-40% of administered dose within 24 hours); remainder sequestered in bone and slowly released over months. Biliary/fecal excretion is negligible (<1%).
Primarily renal excretion of unchanged drug (85%) and minor biliary excretion (15%). Total clearance is 120 mL/min.
