Title: Mixable combination for generating a suspension of stable microbubbles for ultrasonic imaging
Abstract:Gas or air filled microbubble suspensions in aqueous phases usable as imaging contrast agents in ultrasonic echography. They contain laminarized surfactants and, optionally, hydrophilic stabilizers. The laminarized surfactants can be in the form of liposomes. The suspensions are obtained by exposing the laminarized surfactants to air or a gas before or after admixing with an aqueous phase.

Assignee: Bracco International B.V. (Amsterdam, NL)
Filing Date:Aug 23, 2002
Application Number:10/226,244
Claims:1. A mixable combination for generating a suspension of stable microbubbles for use in ultrasonic imaging, said combination comprising: (a) a dry pulverulent formulation comprising at least one film forming surfactant and a hydrophilic stabilizer in the presence of an entrappable gas comprising freon, the film forming surfactant being a saturated phospholipid in lamelar or laminar form and capable of generating a suspension of stabilized gas microbubbles when brought into contact with an aqueous carrier phase; and (b) an aqueous carrier phase mixable with said dry formulation, said dry formulation and said aqueous carrier phase being mixable with each other to produce said suspension of stable microbubbles.

2. The mixable combination of claim 1, wherein the entrappable gas is a mixture of freon with nitrogen.
