And oily progesterone has a long half-life, and it usually takes several weeks to recover
Long-term high-frequency injections will also cause other symptoms such as induration at the injection site, which is not conducive to the health of the tissue at the injection site
The patients are all pregnant women, and it is extremely inconvenient to inject progesterone every day, and the presence of oil solvent in progesterone injection can easily cause problems such as muscle hardening and pain

Embodiment 1
[0055] Preparation of progesterone suspension injection (wet grinding method)
[0056] Prescription (100 sticks):
[0057]
[0058] Preparation Process:
[0059] (1) Prepare grinding media, dissolve 3 g of polyethylene glycol 4000, 0.3 g of Tween 80 and 2.7 g of sodiumchloride in 300 mL of water for injection, stir until completely dissolved, and use as grinding media.
[0060] (2) Pour 200mL of zirconia grinding beads into the grinding chamber, disperse 15g of progesterone in 150mL of grinding media, pour into the chamber, and transfer the remaining drug with the remaining media.
[0061] (3) Circular grinding at 1500 rpm for 10 min to obtain a progesterone suspension, which was dispensed into prefilled syringes under aseptic conditions to prepare 100 prefilled injections.

Abstract
The invention relates to the technical field of medicine. The invention discloses a progesterone suspension long-acting injection and a preparation method thereof and a progesterone suspension injection powder injection, which are used for threatened abortion and assisted reproductive corpus luteum support. The embodiment of the present invention can be made into progesterone suspension or freeze-dried powder injection through micronization and nanometerization, and adding some stabilizers, which can be used for intramuscular or subcutaneous injection. The suspension of the present invention solves the problem of administration of insoluble drugs, uses less auxiliary materials, and has a large drug loading capacity, which can significantly improve bioavailability, achieve a sustained-release effect for a period of one week or more, reduce the number of administrations, and have a biocompatible Good capacity, less irritation, and improve patient compliance. The preparation method of the present invention can adopt media grinding method, solvent replacement-high pressure homogenization method or micro jet method etc. The preparation process of the preparation of the invention is simple and controllable, and industrial production can be realized.
Description
technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a new dosage form of progesterone, in particular to a progesterone suspension long-acting injection and a preparation method thereof, and a progesterone suspension injection powder injection. Background technique [0002] Progesterone, also known as progesterone, is a white or slightly yellow crystalline powder with a melting point of 127-131°C, odorless, stable in air, dextrorotatory, insoluble in water, soluble in ethanol, ether, and chloroform , acetone, dioxane and concentrated sulfuric acid. The chemical name of progesterone is: Pregn-4-ene-3,20-dione, molecular formula: C 21 h 30 o 2 , molecular weight: 314.47, the structural formula is as follows: [0003] [0004] Progesterone is a natural progesterone secreted by the corpus luteum of the ovary and is an important hormone for maintaining pregnancy. Progesterone has many functions during pregnancy, inc...
