Embodiment 1

[0027] Embodiment 1. prepares compound aspirin / clopidogrel / folic acid sheet (1000 pieces amount)

[0028] Recipe:

[0029]

[0030]

[0031] Preparation method: pass the auxiliary materials through a 80-mesh sieve, and set aside. Take 100g of aspirin, 75g of clopidogrel, 0.8g of folic acid, 112g of microcrystalline cellulose, and 40g of lactose, mix them evenly, add an appropriate amount of 10% hypromellose, make soft materials, pass through a 20-mesh nylon sieve to make wet granules, 60 Dry at ±5°C for 2 hours, control the water content of the granules to be below 1.5%, sieve the granules with a 20-mesh sieve, mix them evenly with sodium stearyl fumarate, and press into tablets. Pay attention to avoiding light during the preparation process, and the prepared tablets need to be packed in aluminum-plastic blisters and stored away from light. Each of the prepared compound tablets contains 100 mg of aspirin, 75 mg of clopidogrel and 0.8 mg of folic acid.

Embodiment 2

[0032] Embodiment 2. Preparation of compound aspirin / clopidogrel / 5-methyltetrahydrofolic acid film-coated tablets (1000 pieces)

[0033] Recipe:

[0034]

[0035] Coating prescription

[0036] Coating material: film coating premix 9g

[0037] Coating solvent: purified water 66g

[0038] Preparation method: Weigh aspirin, clopidogrel, 5-methyltetrahydrofolate and PEG6000 according to the prescription amount, and set aside. Add the weighed prescription amount of aspirin, clopidogrel, 5-methyltetrahydrofolate and PEG6000 into the granulator, and granulate at 50°C±5°C. Pass through a 30-mesh sieve for granulation to obtain drug granules, weigh hydroxypropyl cellulose, mannitol, lactose, microcrystalline cellulose and glyceryl behenate, put the weighed drug granules and auxiliary materials into a mixer and mix for 20 minutes, The material is discharged to obtain intermediate particles. The intermediate is inspected, and after passing the test, it is pressed into tablets, an...

Abstract

The invention relates to a pharmaceutical composition containing aspirin, clopidogrel and a folic acid compound. According to the pharmaceutical composition disclosed by the invention, the folic acid compound is prepared from the following components including folic acid, 5-methyltetrahydrofolic acid, formyl tetrahydrofolic acid, folinic acid, calcium levofolinate and medicinal salts of folic acid. The pharmaceutical composition is preferentially prepared from the following components by weight: 50-150mg of aspirin, 50-100mg of clopidogrel and 0.4-2mg of folic acid compound. The invention also relates to an application of the pharmaceutical composition in preparing a medicament for preventing a thromboembolic disease. With the adoption of the pharmaceutical composition, the medicament prepared from the pharmaceutical composition has a remarkable effect of inhibiting formation of thrombus on the basis of effectively inhibiting platelet aggregation; in addition, a patient is convenient to take the pharmaceutical composition, and compliance is improved.

Description

technical field [0001] The invention relates to a pharmaceutical composition containing aspirin, clopidogrel and folic acid compounds and its application, especially a pharmaceutical composition for preventing or delaying vascular embolism diseases, which belongs to the field of pharmacy. Background technique [0002] The incidence of cardiovascular and cerebrovascular diseases in my country is increasing year by year. According to the statistics of the Ministry of Health, there are about 70 million patients with stroke and its sequelae and 60 million patients with coronary heart disease in China. Thrombosis and embolism are the direct causes of cardiovascular and cerebrovascular events such as myocardial infarction and ischemic stroke. Thromboembolic diseases have become the main killer of human health, and antiplatelet therapy is an important intervention to prevent the occurrence of such diseases【 Gao Xuguang. Antiplatelet therapy for the prevention of ischemic stroke. Ch...
