  • Publication number: 20180071436
    Abstract: The invention provides therapeutic particulates including a macrolide, such as rapamycin, in solid state crystalline form, having a size of 20 ?m or less, or 10 ?m or less. The particulates are formed in one method by preparing a composition with a macrolide and first (e.g., xylene) and second (e.g., an alcohol, acetone, or acetonitrile) solvents. In the composition a maximum solubility for the macrolide that is greater than a maximum solubility of the macrolide dissolved in either the first or second solvent individually. The first and second solvents are then evaporated from the composition to provide the macrolide particulates. In another method, the particulates can be formed by a method including sonication and stirring/evaporation steps, and the particulates can be obtained from a supersaturated solution, formed during the process.
