MONOHYDRATE CRYSTAL OF FIMASARTAN POTASSIUM SALT, METHOD FOR PREPARING SAME, AND PHARMACOLOGICAL COMPOSITION COMPRISING SAME Russian patent published in 2017 - IPC C07D403/10 A61K31/513 

FIELD: chemistry.

SUBSTANCE: invention relates to a crystalline form a fimasartan potassium salt monohydrate, where crystalline form of a fimasartan potassium salt monohydrate is characterised by X-ray powder diffraction spectrum peaks using Cu-Kα radiation in diffraction angles with value 2θ, reduced at 6.67±0.2, 7.62±0.2, 11.03±0.2, 15.32±0.2, 16.49±0.2, 20.12±0.2, 25.65±0.2 and 27.28±0.2. Invention also relates to methods of producing a fimasartan potassium salt monohydrate and to a pharmaceutical composition.

EFFECT: technical result is a novel crystalline form of a fimasartan potassium salt monohydrate, which is resistant to moisture and temperature and has same particle size of crystal.
