Abstract

The invention relates to a composite preparation, and preparing method and use thereof. The composite preparation uses Tamsulosin and Dutasteride as active ingredients, wherein Tamsulosin is in the form of enteric pellet, granule or tablet, Dutasteride is in the form of soft capsule, and both of them are filled in a hard capsule. The invention discloses a preparing method of the composite preparation.

Description

technical field [0001] The invention relates to a compound preparation and a preparation method, belonging to the technical field of medicine. Background technique [0002] Benign prostatic hyperplasia (BPH) is a common disease in elderly men, and its incidence increases with age, but there may not be clinical symptoms when there are hyperplasia lesions. The occurrence of BPH is affected by many factors, such as smoking, obesity, drinking, race, genetics, hypertension, diabetes, sex life, socioeconomic status, etc. Although there are many studies on various factors, they are related to the occurrence of BPH The exact relationship has yet to be determined. The incidence of BPH mainly comes from autopsy data, 40% of men aged 50, and 90% of men aged 80 have BPI-I histological changes. In the United States, about 1.7 million BPH patients go to outpatient clinics every year, about 300,000 people undergo prostate surgery, and about 2 billion U.S. dollars are lost each year due t...
