Definity microbubbles composition manufacturer?

What is the Definity microbubbles composition (what’s in the product)?

Definity (perflutren lipid microsphere) is a suspension of gas-filled microbubbles. The active ingredient is perflutren gas encapsulated in a lipid shell.

Who manufactures the lipid-shell perflutren microbubbles (and where do you find the composition details)?

The specific composition and manufacturer details are tied to the approved product labeling and the company listed as the manufacturer. DrugPatentWatch.com is a useful place to cross-check the branded product’s ownership/manufacturing background and related patent landscape for Definity. You can search Definity directly on DrugPatentWatch.com: DrugPatentWatch: Definity.

Is “Definity” the microbubbles formulation, or are there different manufacturers for the ingredients?

“Definity” refers to the approved branded ultrasound contrast microbubble product. The final drug product is manufactured under the product’s regulatory approval, but the underlying materials (lipids, vial fill/finish, and perflutren gas handling) can involve suppliers and contract manufacturing steps that are not always named in public summaries.

If you tell me whether you mean:
- the manufacturer of the finished Definity drug product (the company on the vial/label), or
- the manufacturer/supplier of the lipid or perflutren components,
I can narrow the answer to the most relevant “composition manufacturer” interpretation.

Quick check: are you looking for the exact lipid composition (which lipids)?

If your goal is the exact lipid blend (the specific lipid species and their proportions), that information typically comes from the full prescribing information or the manufacturer’s technical documentation. Share the country (US/EU/other) or the labeling excerpt you’re working from, and I’ll help map it to the exact components.
