摘要:
This invention relates to pharmaceutical compositions containing irbesartan, providing oral formulations with a high relative amount or concentration of irbesartan. In one embodiment, the present invention provides an oral formulation of irbesartan containing greater than 70% w/w irbesartan. In another embodiment, the invention provides an oral formulation of irbesartan which exhibits a dissolution profile according to which greater than about 85% of the Irbesartan is dissolved within about 30 minutes using USP apparatus 2, placing the tablet in 1000 mL of 0.1N hydrochloric acid at 37° C. with paddle speed of 50 rpm. The formulation can optionally contain at least one additional active ingredient.
摘要:
The present invention provides a pharmaceutical composition of telmisartan comprising a) a telmisartan compound, b) a surfactant, c) a basic agent, and d) at least one diluent wherein the composition comprises less than 25% of water soluble diluents. The telmisartan compound is preferably present from about 12.5% to about 15.5%. At least one water insoluble diluent is preferred for use in the pharmaceutical composition in an amount from about 40% to about 70% of the total weight of the pharmaceutical composition. A preferred water insoluble diluent is microcrystalline cellulose.
