PHARMACEUTICAL COMPOSITION COMPRISING POTASSIUM SALT OF TELMISARTAN, AND PREPARATION METHOD THEREFOR

摘要

The present invention relates to a pharmaceutical composition containing a potassium salt of telmisartan, which is an angiotensin II receptor antagonist, and a preparation method therefor. The present invention can provide a granule or powder form of a solid formulation with improved drug dissolution and stability of a telmisartan-containing formulation, and a method for preparing capsules and tablets containing the same. Also, the composition and preparation method according to the present invention are industrially advanced techniques which allow for very easier preparation of telmisartan as a single component or a composite agent combined with other diuretics or high blood pressure-related components compared to a pharmaceutical composition containing telmisartan or salts thereof, thereby achieving significant improvements in terms of production time and cost. The size of a dosage formulation can also be significantly reduced compared to conventional formulations, thereby enhancing medication compliance of patients taking the formulation for a long period of time. In addition, the present invention can provide a composition containing a potassium salt of telmisartan which is capable of significantly improving hygroscopicity of a product, which has been a problem of existing formulations, and maintaining stability in typical packing materials.
