Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor; inhibits VEGFR-1, -2, -3, and PDGFR-β, Kit, and RET.
Technetium Tc-99m sestamibi is a lipophilic cation that accumulates in myocardial cells via passive diffusion across the sarcolemmal and mitochondrial membranes. Its uptake is proportional to myocardial blood flow and viability, allowing for imaging of myocardial perfusion.
AXUMIN (florbetaben F 18) is a diagnostic radiopharmaceutical for PET imaging of beta-amyloid plaques. The recommended dose is 300 MBq (8.1 mCi) administered as a single intravenous bolus injection over 10-15 seconds, followed by a saline flush.
CARDIOLITE (Technetium-99m sestamibi) is administered intravenously. For myocardial perfusion imaging, adult dose: 10-40 mCi (370-1480 MBq), administered as a single bolus.

The terminal elimination half-life is approximately 2.7 hours (range 1.5-5.0 hours) in patients with normal renal function; this supports twice-daily dosing, but may be prolonged in renal impairment.
Terminal elimination half-life: 6-8 hours; prolonged in elderly and renal impairment (up to 12-16 hours).
Renal elimination of unchanged drug accounts for approximately 60% of the administered dose; fecal excretion accounts for approximately 35% (mainly as unchanged drug); biliary excretion contributes to fecal elimination; less than 1% is excreted in urine as metabolites.
Renal: 85-90% as unchanged drug; fecal: <5%
