Problems solved by technology

Since ticagrelor itself is a poorly soluble drug and has poor fluidity, it is difficult to achieve rapid disintegration of the drug by the above common wet granulation method. The inventor practiced the technical solution of the patent application and found that most of the obtained samples disintegrated in more than 1 minute
This technology is actually difficult to solve the rapid collapse problem

Embodiment 1～3

[0046] Embodiment 1~3 preparation of ticagrelor preparation composition

[0047] The first step is the crushing of raw materials.

[0048] The raw material of ticagrelor used in the preparation of the preparation composition of the present invention is the same batch, but it needs to be pulverized before the preparation of the preparation composition of the present invention. The inventor made the batch of raw materials into two kinds of raw materials with different particle sizes by airflow pulverization method , to be distinguished by different sub-batch numbers, wherein, embodiment 1 and 2 adopt the raw material of the 1st sub-batch, and embodiment 3 adopts the raw material of the 2nd sub-batch, and the particle size distribution of the raw material after pulverization is shown in the following table:

Embodiment 4

[0063] Example 4 Investigation of the powder properties of ticagrelor granules

[0064] In order to investigate the fluidity improvement effect of ticagrelor granules on ticagrelor raw materials, to ensure that the direct compression method successfully prepares a qualified preparation composition suitable for disintegration, the ticagrelor prepared in Examples 1-3 The particles were tested for intermediate control as follows, and the results are shown in the table below.

[0065] Table 4 Powder Science Investigation of Ticagrelor Granules

[0066]

[0067] From the above investigation, it can be seen that after ticagrelor is prepared into ticagrelor granules by spray drying method, its fluidity is obviously improved.

Abstract

The invention provides a ticagrelor preparation composition. The composition is prepared from the following components in percentage by weight: 25-35 percent of ticagrelor granules, 60-70 percent of filler, 3 percent of a disintegrating agent and 2 percent of a lubricating agent. The ticagrelor granules are prepared by a spray-drying method, the content of main drugs in the granules can be increased, and the tablet weight can be reduced to improve the compliance of patients on the one hand; and on the other hand, the ticagrelor granules are prepared by the spray-drying method, the process is smooth, and the material mobility is good, and the process feasibility during high-dose drug loading is improved.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a ticagrelor preparation composition and a preparation method thereof. Background technique [0002] Ticagrelor is a platelet aggregation inhibitor with the chemical name: (1S,2S,3R,5S)-3-[7-[(1R,2S)-2-(3,4-difluorophenyl) Cyclopropylamino]-5-(propylthio)-3H-[1,2,3]triazol[4,5-d]pyrimidin-3-yl]-5-(2-hydroxyethoxy)cyclopenta Alkane-1,2-diol. The structural formula is as follows: [0003] [0004] Ticagrelor was developed by AstraZeneca for use in patients with acute coronary syndrome (unstable angina, non-ST-segment elevation myocardial infarction, or ST-segment elevation myocardial infarction), including drug therapy and percutaneous coronary Patients undergoing interventional (PCI) therapy to reduce the incidence of thrombotic cardiovascular events. [0005] In 2010, its tablets were first approved for marketing in the UK. Since the daily d...
