Abstract

The invention relates to the field of pharmaceutical chemicals, and in particular relates to a rivaroxaban pharmaceutical composition and a preparation method thereof; the pharmaceutical composition consists of a rivaroxaban active substance, a solubilizer, a binding agent, a lubricant, a filling agent and a disintegrating agent, wherein the rivaroxaban active substance is not subject to hydrophilic treatment; and the solubilizer accounts for about 1.5%-3.5% in the entire composition in percentage by mass. The rivaroxaban pharmaceutical composition is stable and good in dissolution; and the preparation method is simple and convenient and is energy-saving, and the preparation method is applicable to industrial production.

Description

technical field [0001] The invention relates to a rivaroxaban pharmaceutical composition suitable for oral application and a preparation method thereof, belonging to the field of medicinal chemistry. Background technique [0002] Rivaroxaban, whose chemical name is 5-chloro-N-(((5S)-2-oxo-3-(4-(3-oxomorpholin-4-yl)phenyl)-1,3 -Oxazolin-5-yl)methyl)thiophene-2-carboxamide, the chemical structural formula is as follows: [0003] [0004] It is a low molecular weight and oral coagulation factor Xa inhibitor, which is used to prevent or / and treat various thromboembolic diseases (see WO01 / 47919). JANSSENPHARMS has developed and launched oral tablets of rivaroxaban. Said rivaroxaban is a publicly known compound. [0005] Rivaroxaban has poor solubility in water, about 7 mg / L, thus resulting in poor dissolution in the composition. A low dissolution rate in the pharmaceutical composition may lead to low bioavailability, so it can be seen that the bioavailability of rivaroxaba...
