LUMASON vs OPTISON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LUMASON (sulfur hexafluoride lipid-type A microspheres) is an ultrasound contrast agent that consists of gas-filled microspheres. After intravenous injection, the microspheres enhance the ultrasound signal by increasing the backscatter of ultrasound waves, thereby improving the visualization of cardiac chambers, endocardial borders, and vascular structures.
OPTISON consists of perflutren protein-type A microspheres that act as an ultrasound contrast agent by increasing the echogenicity of blood, improving the visualization of cardiac chambers and intracardiac blood flow.
0.5 mL intravenous bolus injection, followed by 5 mL saline flush. May repeat once if needed.
0.5 mL intravenous bolus; may repeat with additional 0.5 mL dose if needed. Administer via peripheral intravenous line at 1 mL/sec.

Terminal elimination half-life is approximately 2 hours (range 1.5–2.5 hours) after intravenous administration, reflecting rapid clearance and supporting use as a diagnostic agent without significant accumulation.
Plasma half-life of perfluoropropane gas is approximately 2.4 minutes after intravenous administration, with rapid equilibration and elimination via the lungs.
Primarily renal; >90% excreted unchanged in urine within 24 hours. Fecal elimination is negligible (<1%).
Primarily eliminated via pulmonary excretion of the perfluoropropane gas; <1% renal excretion of the intact microsphere components.
