  • Publication number: 20220354778
    Abstract: The present invention includes compositions and methods for treating and delivering medicinal formulations using an inhaler. The composition includes a space filled flocculated suspension having one or more flocculated particles of one or more active agents and a hydrofluoroalkane propellant. A portion of the one or more flocculated particles is templated by the formation of hydrofluoroalkane droplets upon atomization and the templated floc compacts upon the evaporation of the hydrofluoroalkane propellant to form a porous particle for deep lung delivery.
