Abstract

The invention relates to a mirabegron composition and a preparation method thereof and belongs to the technical field of pharmacy. According to the technical scheme, the mirabegron sustained-release composition is characterized in that every 1000 tablets comprise 25-50 g of mirabegron, 15-45 g of hydroxypropyl methylcellulose (K4M), 0.15-0.3 g of butylated hydroxytoluene, 50-160 g of polyoxyethylene (POLYOX N80), 10-32 g of polyethylene glycol 6000, 0.8-1.4 g of magnesium stearate and 8-15 g of powdery silicon dioxide. Through implementation of the technical scheme, a clinic medicine which is excellent in dissolution behavior is obtained. Due to the adding of silicon dioxide, the sustained release of active matter mirabegron is performed to some extent.

Description

technical field [0001] The invention relates to a mirabegron composition and a preparation method thereof, belonging to the technical field of pharmacy. Background technique [0002] Overactive bladder (OAB) is a syndrome characterized by urinary urgency symptoms, often accompanied by frequent urination and nocturia, with or without urge incontinence, which obviously affects the daily life and social activities of patients, and has been Become a major disease that plagues people.
