Title:
METHOD FOR PREPARING PROGESTERONE PARTICULATE, PREPARED PROGESTERONE PARTICULATE AND INJECTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/135352
Kind Code:
A1
Abstract:
Disclosed is a method for preparing a progesterone particulate, especially a crystal or powder. The method comprises: step 1, dissolving progesterone in a solvent to provide a progesterone solution; step 2, pumping the progesterone solution into a high-speed shearing progesterone precipitation solvent at a predetermined speed to precipitate progesterone; and step 3, separating the precipitate and freeze-drying same to obtain the progesterone particulate, wherein the progesterone particulate being a progesterone crystal or progesterone powder. By using the method of the present invention, a micron-sized progesterone crystal or powder having good stability can be obtained. The progesterone injection prepared by using same not only achieves a sustained release effect of at least 5 days, but also has good stability. The method of the present invention is simple to operate, has low cost, and is easily scaled up for industrial production.
