  • Co-polymer stabilizers for hydrofluoroalkane dispersions
    Patent number: 8586007
    Abstract: The use of biodegradable and biocompatible lactide-based nonionic amphiphiles to stabilize a model drug (salbutamol base) dispersion in hydrofluoroalkane (HFA) propellant is disclosed. The results have industrial applicability to the development of HFA-based dispersion pressurized metered-dose inhaler formulations.
