Abstract

The invention provides a sodium prasterone sulfate sustained-release tablet and a preparation method thereof. The sodium prasterone sulfate sustained-release tablet comprises, by weight, 10% to 90% of sodium prasterone sulfate, 5% to 75% of framework matierals, 0.1% to 80% of filler and 0.1% to 5% of lubricant. The sodium prasterone sulfate sustained-release tablet in the embodiment only needs to be taken once a day and is good in patient compliance. The stable blood concentration can be provided, the limited concentration can be kept for a long time, and thus, the toxic and side effects of the medicine are reduced, and the safety of the medicine is improved.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, in particular, the invention relates to prasterone sulfate sodium sustained-release tablets and a preparation method thereof. Background technique [0002] Prasterone sulfate sodium is mainly used clinically to ripen the cervix before induction of labor at term. [0003] CN1509719 discloses a new application of prasterone sulfate sodium for treating menopausal syndrome, especially women's senile and atrophic vaginitis. CN102429912 discloses a pharmaceutical composition prepared by micronized prasterone or prasterone sulfate sodium and its application, and the medicine can be prepared into an ordinary tablet for oral administration. [0004] However, the current research on prasterone sulfate sodium preparations still needs to be deepened. Contents of the invention [0005] The present invention aims to solve one of the technical problems in the related art at least to a ce...
