Embodiment 1

[0052] In this embodiment, the drug-loaded pellet core was prepared according to the prescription shown in Table 1 below and the operation steps described below:

[0053] Preparation:

[0054] Pass prasterone sulfate sodium through an 80-mesh sieve, weigh the sieved prasterone sulfate sodium and the blank ball core according to the prescription amount shown in Table 1, and use a centrifugal granulator and a fluidized bed to granulate respectively. After the granulation is completed, the drug-loaded pellet core is obtained.

[0067] prescription:

[0068] Prasterone Sulfate Sodium 200g

[0069] Blank ball core (sucrose ball core) 274g

[0070] 8% PVP-k30 solution (solvent is 90% ethanol) 150g

[0071] Preparation Process:

[0072] Pass prasterone sulfate sodium through an 80-mesh sieve, weigh the prescription amount, and pour it into the hopper of the centrifugal granulator. Pour blank pellet cores into a centrifugal granulator for granulation, set the air inlet pressure to 0.7 bar, atomization pressure to 2 bar, thimble pressure to 1 bar, feeding speed to 3 rpm, peristaltic pump efficiency to 10%, and turntable speed to 135rpm, spray 8% PVP-k30 solution (the solvent is 90% ethanol), and the drying temperature is 55°C. After the granulation is finished, about 480 g of drug-loaded pellet cores are obtained.

Abstract

The invention provides a sodium prasterone sulfate sustained-release capsule and a preparation method thereof. The sodium prasterone sulfate sustained-release capsule comprises sodium prasterone sulfate and auxiliary materials acceptable on pharmacy. The sodium prasterone sulfate sustained-release capsule can achieve 12-hour sustained release, and is stable in quality, high in bioavailability and good in medication compliance.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to prasterone sulfate sodium sustained-release capsules and a preparation method thereof. Background technique [0002] Prasterone sulfate sodium is currently marketed in the form of injection and injection powder, which is mainly used clinically to ripen the cervix before induction of labor in full-term pregnancy. [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 micronizing prasterone or prasterone sulfate sodium and its application. [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 certain extent....
