  • Preparation of micronized particles of an antimuscarinic compound by hydrodynamic cavitation
    Patent number: 9925168
    Abstract: Crystalline micronized particulate of a glycopyrronium salt may be prepared by hydrodynamic cavitation. The resulting drug particles are physically stable with regard to agglomeration and/or aggregation on storage.
    Type: Grant
    Filed: January 19, 2017
    Date of Patent: March 27, 2018
    Assignee: CHIESI FARMACEUTICI S.p.A.

  • System for crystalizing chemical compounds and methodologies for utilizing the same
    Patent number: 9732068
    Abstract: A system including a fluid receiver defined by a crystallization chamber, three or more fluid input conduits, wherein each fluid input conduit is configured to direct a fluid into the crystallization chamber such that the fluids from the fluid input conduits converge on a single spatial coordinate (X—Y—Z) within the crystallization chamber, and a fluid outlet body portion. A process for crystallization of the chemical compound is also disclosed. Polymorphs of paracetamol, carbamazapine, ketoprofen, atorvastatin, and itraconazole also are disclosed.
