Abstract

The invention relates to a mesalazine enteric sustained-release tablet preparation method, and belongs to the technical field of medicine. According to the present invention, a mesalazine enteric sustained-release tablet core is prepared by using wet granulation and tableting, and the mesalazine enteric sustained-release tablet is prepared through enteric coating, wherein each tablet contains 1.2g of mesalazine.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a preparation method of mesalamine enteric-coated sustained-release tablets each containing 1.2 g of mesalamine. Background technique [0002] Ulcerative colitis (ulcerative colitis, UC) is a chronic, inflammatory and ulcerative disease that occurs in the colonic mucosa. Due to the wide range of lesions, recurrent attacks, and high possibility of cancer, UC is currently recognized as one of the most difficult diseases to cure. Ulcerative colitis is very common in western countries, and the number of cases reported in my country has increased significantly in recent years with the improvement of living standards. According to the statistics of cases in many hospitals, the incidence of UC in China is about 30 cases per 100,000 people. Of course, the actual cases may be more. Ulcerative colitis is a common disease of the digestive system and an important cause of chronic diarrhea in China,...
