  • Patent number: 5376359
    Abstract: A method of making a stabilized aerosol drug formulation is disclosed, along with the formulations so produced and metered drug inhalers containing the same. The method comprises combining a solid particulate drug composition with a fluoropolymer in a liquid fluorocarbon aerosol propellant to form a stable suspension. Further stabilization can be achieved by cooling the suspension for a time and to a temperature sufficient to adsorb the fluoropolymer to the solid particulate drug composition in the liquid fluorocarbon aerosol propellant. Preferred propellants for carrying out the invention are 1,1,1,2-tetrafluoroethane, heptafluoropropane, and mixtures thereof, and preferred fluoropolymers for carrying out the invention are fluoropolyethers.
