MACROTEC vs VIZAMYL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Not applicable for diagnostic use.
Vizamyl is a radiopharmaceutical that binds to beta-amyloid plaques in the brain, enabling visualization via PET imaging.
5 mCi (185 MBq) intravenously as a single dose for lung perfusion imaging.
For diagnostic imaging: 370 MBq (10 mCi) administered as a slow intravenous bolus (approximately 1 mL/sec).

6 hours; prolonged in renal impairment (up to 30 hours in ESRD)
Terminal elimination half-life is approximately 45-50 minutes in patients with normal renal function, allowing for rapid clearance and early imaging within 4 hours post-injection.
Renal: 95% as unchanged drug; biliary/fecal: <5% as metabolites
Primarily renal excretion as unchanged drug (90-95%) with the remainder excreted via feces (5-10%).
