  • Publication number: 20200197311
    Abstract: Embodiments of the invention relate to a process for enhancing the bioavailability of poorly soluble active ingredients, and to formulations of powders made by such process. Embodiments of the invention comprise a spinodal decomposition method by which low, sparingly or poorly-soluble materials are converted to amorphous materials with, improved or enhanced solubility suitable for therapeutic use. The powder formulations are useful for the treatment of diseases and conditions, especially respiratory diseases and conditions.

  • Patent number: 8614232
    Abstract: An injectable depot formulation comprising crystals having structure (I) wherein R is (FII) and the X50 value of the crystals is from 1 to 200 microns. Depot formulations containing crystals of iloperidone or its metabolites have the following advantages: (i) release of the crystals in plasma can be correlated with the size of the crystals; (ii) absorption of the crystals in plasma can be correlated with the size of the crystals; (iii) the particle size of the crystals can be controlled by crystal engineering and/or milling; and (iv) the crystals are stable upon storage, and stable to sterilization procedures, such as gamma irradiation.

  • Patent number: 6423722
    Abstract: 33-Epichloro-33-desoxyascomycin of formula I and various tautomeric or forms thereof, in crystalline form, such as Form A and Form B. Their preparation involves appropriately converting amorphous compound of formula I, or compound of formula I in other than Form A, or compound of formula I in other than Form B, respectively, from a solution thereof under crystallization-inducing conditions or conditions inducing preferential crystallization of Form A or B, respectively. Such crystals are particularly indicated for use in the preparation of topical galenical forms of the compound for pharmaceutical use, e.g. creams, emulsions and ointments.
