Problems solved by technology

However, direct micronization of drugs has a common disadvantage: micronized products are very easy to agglomerate, often making it unable to fully demonstrate the advantages of micronization. The co-grinding method used in the patent can reduce this aggregation phenomenon
Solid dispersion technology can improve the dissolution rate and bioavailability of ezetimibe, but this preparation method is not very satisfactory, because the solid dispersion body is easy to age after a long time; and it needs to use a large number of carriers and some other medicinal products. Excipients, resulting in too large a volume of the preparation, which is not easily accepted by patients

Embodiment 1

[0030] Example 1 One-step granulation of micronized ezetimibe

[0031] According to conventional methods, the ezetimibe API is first micronized, and the equipment used for the micronization treatment may be a jet mill, a ball mill or a fluid energy mill, or other equipment conventionally used in the art may be used. The particle size of ezetimibe should be controlled to be less than 10 μm by pre-crushing.

Abstract

The invention relates to a preparation method of an ezetimibe medicine composition. The preparation method comprises the following steps: 1, suspending ezetimibe in a proper solvent to prepare an uniform ezetimibe micron-sized suspension; 2, adding the suspension into a diluent of the medicine composition in a spraying manner and drying to prepare particles and powder of the ezetimibe medicine composition; and 3, preparing the particles and the powder into the ezetimibe medicinal minimum dose unit. Firstly, the medicine is prepared into the micron-sized suspension, granulation is carried out in a one-step granulation manner, the medicine is added into the diluent and finally, the medicinal minimum dose unit is prepared. The preparation method has the benefits that the effect of the preparation method is superior to that of a method in which micronization is carried out after the slightly soluble medicament is separately micronized; and the operation is simple and the large scale production is easy.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a preparation method of an ezetimibe pharmaceutical composition. Background technique [0002] Ezetimibe (Ezetimibe), the chemical name is 1-(4-fluorophenyl)-3(R)-[3-(4-fluorophenyl)-3(S)-hydroxypropyl]-4(S )-(4-hydroxyphenyl)-2-azetidin (azetidin) ketone, its structural formula is: [0003] [0004] Ezetimibe is an oral, potent lipid-lowering drug that works differently from other lipid-lowering drugs, such as statins or bile acid sequestrants. Its mechanism of action is to attach to the brush border of small intestinal villi, inhibit the absorption of cholesterol, thereby reducing the transfer of cholesterol from the small intestine to the liver, reducing the storage of cholesterol in the liver and increasing the clearance of cholesterol in the blood. But it does not increase bile secretion (eg, bile acid sequestrants) and does not inhibit cholesterol synthes...
