  • Method for preparing spherical Clopidogrel Hydrogen Sulfate polymorph I
    Patent number: 9815848
    Abstract: This invention provides a new preparation method of Clopidogrel Hydrogen Sulfate spherical crystal form I, using single 2-butanol as solvent, controlling the concentration, addition way and addition speed of sulfuric acid used to salify to shorten the process time, thus separating out Clopidogrel Hydrogen Sulfate from solution system stably with spherality. And the Clopidogrel Hydrogen Sulfate obtained complies with the requirements of the follow-up process on residual solvent, bulk density and mobility.

  • Amorphous allisartan isoproxil, preparation method therefor, and pharmaceutical composition containing amorphous allisartan isoproxil
    Patent number: 9670184
    Abstract: The present invention relates to an amorphous allisartan isoproxil which is an angiotensin II receptor blocker with good flowability and a large bulk density and with no obvious electrostatic phenomenon; the find of the amorphous allisartan isoproxil can effectively reduce the generation of dust pollution during the production, thereby providing convenience the production of allisartan isoproxil. The present invention also relates to a pharmaceutical composition containing the amorphous allisartan isoproxil. The pharmaceutical composition is highly stable, and allisartan isoproxil formulation prepared from the pharmaceutical composition can effectively ensure the quality of the drug.
