Abstract

The invention relates to a dabigatran etexilate medicine composition and a preparation method thereof. The dabigatran etexilate medicine composition consists of a pill I and a pill II, wherein the pill I contains an active ingredient, a blank pill core material, an adhesive, an anti-sticking agent and / or an isolation material, wherein the active ingredient is dabigatran etexilate or a pharmaceutically acceptable salt, hydrate or solvate thereof; and the pill II contains a medicinal organic acid, a pill core material, an adhesive, an anti-sticking agent and / or an isolation material. The discovery shows that the active ingredient and the organic acid are respectively contained in the two different pills, so that the requirement of dissolving out the active ingredient is satisfied, and the active ingredient is more uniformly dissolved out; and in addition, an isolation effect between the active ingredient and the organic acid is enhanced, so that the stability of the dabigatran etexilate medicine composition is improved.

Description
