  • Patent number: 11013736
    Abstract: The invention discloses an oral solid preparation containing any one, or a mixture of two or more of crystalline form I, II, III, and IV of the compound represented by formula (A). The oral solid preparation of the present invention disintegrates rapidly, increasing dissolution rate thereof, thereby improving bioavailability. In particular, it is possible to solve the problem that an active material (active ingredient), which is high hygroscopic and becomes sticky after moisture absorption, can not be effectively disintegrated by conventional disintegrants. The present invention further relates to a use of the oral solid preparation in preparing an angiotensin II receptor antagonist or a use thereof in preparing medicine for preventing and/or treating hypertension, chronic heart failure and diabetic nephropathy.

  • Patent number: 11008311
    Abstract: The preparation method for the compound, composition and application thereof in preparing an angiotensin II receptor antagonist or application in preparing medicine for preventing and/or treating hypertension, chronic heart failure and diabetic nephropathy. After entering a human body, when releasing azilsartan, the compound releases hydroxyligustrazine or NO at the same time, thus generating a synergistic effect with azilsartan. The compound therefore has stronger and longer blood pressure lowering effect, more obvious and longer lasting heart rate lowering effect and high safety, and achieves ideal protective effect for heart and kidney functions.
