Abstract

The invention discloses an Apixaban tablet, which comprises the following components in parts: 1 part of Apixaban, 10-20 parts of water-soluble carrier material, 30-60 parts of filling agent, 5-10 parts of disintegrating agent and 5-10 parts of glidant. The Apixaban tablet provided by the invention improves the deficiencies in the prior art that the extracorporeal dissolution rate and the bioavailability is low. The preparation method of the Apixaban tablet disclosed by the invention is simple to operate, has good reproducibility, and is suitable for large-scale production. The Apixaban tablet is mainly used for the anti-thrombosis purpose.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an apixaban tablet and a preparation method thereof. Background technique [0002] Apixaban is a novel oral direct factor Xa inhibitor with the chemical formula 1-(4-methoxyphenyl)-7-oxo-6-[4-(2-oxopiperidin-1-yl) )phenyl]-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxamide. Molecular formula is C 25 h 25 N 5 o 4 , the molecular weight is 459.50. The structural formula is as follows: [0003] [0004] Cardiovascular and cerebrovascular diseases are characterized by their high incidence, high recurrence rate, high disability rate, and high mortality rate, which have seriously threatened people's health. At present, one out of every five adults in my country suffers from cardiovascular and cerebrovascular diseases, and one person dies from cardiovascular and cerebrovascular diseases every 10 seconds. The number of deaths due to cerebrovascular disease...
