Definity microbubble composition and approval?

What is Definity’s microbubble composition?

Definity (perflutren lipid microsphere injection) is a suspension of microbubbles made from perflutren gas contained in a lipid shell. The product is designed for ultrasound imaging and is administered as an injection.

How does Definity work for ultrasound imaging?

The microbubbles enhance ultrasound contrast by increasing the reflectivity of blood to ultrasound waves. The lipid-encapsulated perflutren bubbles stay intravascular long enough to improve visualization during echocardiography.

What approvals has Definity received?

Definity is an FDA-approved ultrasound contrast agent. The drug is marketed for echocardiographic enhancement in patients where image quality is insufficient for accurate diagnosis.
