Definity generic name?

What is “Definity” and what generic name does it use?

Definity is the brand name for a contrast agent used in ultrasound imaging. Its generic name is perflutren lipid microspheres (often written as perflutren lipid microsphere).

Is there a true generic version of Definity?

For many ultrasound contrast products, substitutes may be limited or depend on availability and regulatory approvals by country. If you mean “generic” as in an FDA-approved equivalent, the key is the active ingredient: perflutren lipid microspheres.

If you tell me your country (or whether you need an FDA/EU/UK listing), I can tailor the answer to the specific generic/alternate products available there.
