    • The present invention relates to the field of pharmaceutical chemistry. Disclosed herein is a crystalline form of azilsartan medoxomil potassium, which is substantially pure. The crystalline form is crystalline form A, form B, form C, form D, form E, form F, form G, form H, form I, form J, form K or form L. The substantially pure crystalline forms of azilsartan medoxomil potassium of the invention generally have good properties such as high solubility, high bioavailability, good stability, long shelf life and good antistatic property. The crystalline forms of azilsartan medoxomil potassium generally exhibit an excellent performance in reducing clinical systolic blood pressure (SBP) and average 24-hour SBP. Disclosed herein are methods of preparing the substantially pure crystalline forms of azilsartan medoxomil potassium, pharmaceutical compositions comprising the crystalline forms, and preparation methods and uses thereof.
