Abstract

A dripping pill of Aipuliete is prepared through superfine pulverizing and the conventional steps for preparing dripping pills.

Description

technical field [0001] The invention relates to a pharmaceutical preparation and a preparation method thereof, in particular to Apret dripping pills and a preparation method thereof. Background technique [0002] Apretide is a selective non-competitive steroid type II 5α-reductase inhibitor for the treatment of benign prostatic hyperplasia, its mechanism of action is to reduce the production of dihydrotestosterone in the prostate by inhibiting the conversion of testosterone into dihydrotestosterone content, leading to atrophy of the prostatic body of hyperplasia. [0003] The pharmacokinetics of Apretide presents a two-compartment model, it is rapidly absorbed in the digestive tract, and the drug can be detected in the serum 0.25 hours after administration. The plasma concentration reaches the peak in 3 to 4 hours, and the half-life of the elimination phase (t 1 / 2 β) is 7.5 hours. On the 6th day of continuous administration (5 mg / time, twice a day), the blood drug concentr...
