Abstract

The invention relates to a method for preparing apixaban tablets. The method comprises the following steps: (1) uniformly mixing apixaban, an excipient, a disintegrating agent, a surfactant and a lubricating agent, performing wet granulation, screening the prepared soft material by using a 20-mesh sieve, granulating, drying and finishing the obtained particles, and collecting the dried particles with the particle size being between 20 meshes and 80 meshes; and (2) mixing the prepared particles with the lubricating agent for 30 minutes and tabletting, wherein the hardness of the tablets is 50-60N. In order to improve the dissolubility, a method for adding the surfactant into the prescription is adopted. According to the method, the dissolubility of the apixaban can be improved, and the problem is well solved, so that the bioavailability of the medicine is improved, and an excellent treatment effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of western medicine preparations, and particularly relates to a preparation method of apixaban tablets. Background technique [0002] Agaoxaban is a new type of oral direct factor Xa inhibitor with the chemical formula of 1-(4-methoxyphenyl)-7-oxo-6-[4-(2-oxopiperidin-1-yl) ) Phenyl]-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-methideamine. The molecular formula is C25H25N5O4 and the molecular weight is 459.50. The structural formula is as follows: [0003] [0004] Atrial fibrillation (AF) is the most common type of arrhythmia clinically, and it is an important independent risk factor for stroke. AF patients are at risk of cerebral embolism or transient ischemic attack (TIA) in non-AF patients 4-5 times. In addition, patients with AF usually have poorer stroke outcomes and higher mortality and disability rates. The fatality rate of AF patients within 1 year after stroke is as high as 50%. Therefore, it i...
