Solid dispersions comprising Telmisartan and the preparation method thereof

摘要

The solid dispersions comprising telmisartan and a manufacturing method thereof, according to the present invention, unlike conventional methods requiring a low yield, can manufacture telmisartan of a high yield through simple and short steps by using a relatively inexpensive raw material, can secure excellent quality through reduction of generation of decomposition products, and can manufacture the solid dispersions on a mass production basis to be commercially available. Therefore, the solid dispersions of novel crystalline polymorph of the telmisartan of the present invention has improved storage stability and solubility, and can be synthesized at a high yield, thereby being expected to be very useful in the manufacture of pharmaceuticals.
