Abstract

The invention discloses a process method and a composition for improving flowability of piperacedryl isethionate, and belongs to the field of pharmaceutical preparations. The method comprises the step of granulating pepericide isethionate and pharmaceutically acceptable auxiliary materials, the tap density of the obtained granules is 0.55-0.72 g/mL, and the angle of repose is smaller than or equal to 44 degrees. According to the process method disclosed by the invention, when the piperacipril isethionate composition is subjected to capsule filling, the particle fluidity is relatively good, and the prepared piperacipril isethionate capsule is uniform in content, good in stability and controllable in quality. The preparation method is convenient to operate, easy to master and adjust and good in production amplification controllability.

Description

technical field [0001] The invention relates to a pharmaceutical preparation and a preparation method thereof, in particular to a process method and a composition for improving the fluidity of palbociclib isethionate, belonging to the technical field of medicine. Background technique [0002] Breast cancer is one of the major malignant tumors that endanger the health of women around the world. According to the report of the International Cancer Research Center of the World Health Organization, there were about 1.677 million new cases of female breast cancer in the world in 2012, accounting for 25.2% of female malignant tumors. The age-standardized incidence rate of breast cancer is 43.3 / 100,000, ranking first in the incidence of female malignant tumors; the age-standardized mortality rate of female breast cancer in the world is 12.9 / 100,000, ranking first in the order of female malignant tumor deaths. Breast cancer has become a major public health problem in today's society....
