Embodiment 1

[0124] Preparation of ticagrelor crystal form A

[0125] Under stirring, dissolve 2g of ticagrelor in 3ml of N,N-dimethylformamide at 25-30°C, and then add dropwise to 30ml of methyl tert-butyl ether cooled to 0-10°C. Continue to stir and crystallize at this temperature for 2 hours, filter, wash the filter cake with n-hexane, then dry under reduced pressure at 40-45°C for 6 hours, and then dry under reduced pressure at 80-85°C to obtain ticagrelor crystal form A, 1.71g.

[0126] The measured X-ray powder diffraction pattern is shown in figure 1 , The measured value is shown in the following table (take the measured value corresponding to the diffraction peak with a relative intensity greater than 1%):

[0127]

Embodiment 2

[0129] Preparation of ticagrelor crystal form A

[0130] Under stirring, dissolve 2g of ticagrelor in 5ml of N,N-dimethylformamide at 20-25°C, then add to 30ml of n-heptane, lower the temperature to 5-10°C, and continue to stir and crystallize for 5 hours After filtering, the filter cake was washed with n-heptane, then dried under reduced pressure at 50-55°C for 5 hours, and then dried under reduced pressure at 70-75°C to obtain ticagrelor crystal form A, 1.65 g. The measured X-ray powder diffraction pattern and figure 1 similar.

Embodiment 3

[0132] Ticagrelor tablets and preparation method thereof

[0133] Composition of prescription:

[0134]

[0135] Preparation:

[0136] 1. Dry the microcrystalline cellulose, mannitol, sodium carboxymethyl starch and magnesium stearate in Table 3 above at about 85°C for 12 hours, and set aside.

[0137] 2. Add the sodium carboxymethyl starch and mannitol twice in equal amounts, mix for 10 minutes, and rotate at 10 rpm to obtain mixture (I).

[0138] 3. Mix ticagrelor crystal form A (D90 less than 100μm) with the above mixture (I) for 10 minutes at a speed of 10 revolutions per minute to obtain mixture (II).

[0139] 4. Mix the above mixture (II) and microcrystalline cellulose for 10 minutes at a speed of 10 revolutions per minute to obtain a mixture (III).

[0140] 5. Add magnesium stearate to the above mixture (III) and mix for 10 minutes at a speed of 10 rpm to obtain mixture (IV).

[0141] 6. Press the mixture (IV) into tablets, and control the tablet weight within ±5% of the average ta...

Abstract

The invention relates to a tablet composition of anticoagulation medicament ticagrelor and a preparation method of the tablet composition. The tablet composition comprises ticagrelor, a filling agent, a disintegrating agent, a lubricating agent and / or an adhesive. The tablet composition is characterized in that a tablet is prepared by virtue of a direct compression method or a dry granulation compression method. The preparation method has the beneficial effects that the operation steps are simple, the controllability of process parameters is good, and the process repeatability is good; meanwhile, the crystal type transform and impurity increase which can be caused in damp and hot processes of ticagrelor are avoided; the prepared ticagrelor tablet has a similar in vitro dissolution behavior with a primarily researched preparation. Therefore, the ticagrelor tablet is stable and controllable in quality and good in treatment effect and safety.

Description

Technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and specifically relates to a ticagrelor oral pharmaceutical composition and a preparation method thereof. Background technique [0002] Ticagrelor, also known as ticagrelor, is chemically named (1S,2S,3R,5S)-3-[7-{[(1R,2S)-2-(3,4-difluorobenzene Yl)cyclopropyl]amino)-5-propylthio-3H-1,2,3-triazolo[4,5-d]pyrimidin-3-yl]-5-(2-hydroxyethoxy) -1,2-Cyclopentanediol, the chemical structure is shown in formula I: [0003] [0004] Ticagrelor is a cyclopentyltriazolopyrimidine compound and is the first reversible P2Y12 platelet inhibitor. It is mainly used to reduce acute coronary syndrome (unstable angina, non-ST-segment myocardial infarction, ST-segment myocardial infarction) The incidence of thrombotic cardiovascular events in patients; it can also be used to reduce cardiovascular death, myocardial infarction and ischemic stroke in patients (>50 years of age) diagnosed with peripher...
