Abstract

A stable abiraterone acetate tablet and a preparing method thereof are disclosed. The abiraterone acetate tablet is free of aerosil and is prepared from following components: abiraterone acetate, lactose monohydrate, microcrystalline cellulose, croscarmellose sodium, povidone, sodium dodecylsulfate and magnesium stearate. The abiraterone acetate tablet has characteristics of stability, simple preparation process and controllability.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and more specifically relates to a stable abiraterone acetate preparation and a preparation method thereof. Background technique [0002] Abiraterone acetate, Abiraterone acetate, chemical name: (3β)-17-(3-pyridine) androst-5,16-dien-3-yl acetate, chemical structure: [0003] [0004] Abiraterone acetate is an oral 17α-hydroxylase / C17,20-lyase inhibitor, which can reduce androgen levels by inhibiting the key enzyme in androgen synthesis—CYP450c17, and has effects on androgen in testis and other parts of the body. Hormones have an inhibitory effect. [0005] Shenzhen Wanle Pharmaceutical Co., Ltd. disclosed four polymorphs of abiraterone acetate and their preparation methods in Chinese patent application CN200910189173.1 (application number, hereinafter referred to as patent application No. 173.1). Four crystal forms of abiraterone acetate: A, B, C and D. Polymorph C prov...
