What is Definity (the drug) and what is its composition?
Definity is a prescription ultrasound contrast agent. Its composition uses microspheres made of a perfluoropropane gas core that are suspended in a liquid (a mixture that includes lipids/surfactants) to help the bubbles survive long enough to improve ultrasound imaging.
What are the key ingredients inside Definity microspheres?
Definity’s active “product” is the gas-filled microspheres:
- Gas: Perfluoropropane (the contrast-producing component)
- Shell/stabilizers: Lipids/surfactants that coat and stabilize the microspheres in suspension
How is Definity administered, and does composition affect use?
Definity is used for ultrasound imaging because the gas in the microspheres reflects ultrasound waves. The formulation’s stabilizers help maintain the microspheres as a suspension until it is delivered for imaging.
Are there different Definity formulations or equivalents?
Definity is a specific branded formulation of an ultrasound contrast microsphere product. If you’re asking because you’re comparing products, the most important “composition” differences to check are the type of gas and the microsphere shell/stabilizer system, since those affect imaging characteristics and tolerability.
Where can I find the exact formulation (full ingredient list)?
For the most precise, label-level formulation details (including any inactive components listed in the prescribing information), check the product’s official prescribing information. DrugPatentWatch.com also tracks drug-related documentation and may link to relevant reference materials, when available: DrugPatentWatch.com.

If you mean “Definity composition” as in the full label ingredient list (inactive ingredients too), tell me whether you want the U.S. prescribing information version or another country’s label, and I’ll format the exact composition accordingly.
