Embodiment 1
[0012] Embodiment 1 common tablet
[0013] Proanthocyanidins 25g
[0014] Clopidogrel Bisulfate 25g
[0015] Microcrystalline Cellulose 250g
[0016] Lactose 20g
[0017] 10% starch slurry appropriate amount
[0018] Magnesium Stearate 1.5g
[0019] Preparation process: Weigh the prescribed amount of proanthocyanidins, clopidogrel bisulfate, microcrystalline cellulose, and lactose and mix evenly. In addition, add an appropriate amount of 10% starch slurry to the mixed powder, mix evenly, make soft material, pass through a 18-mesh nylon sieve to make wet granules, and dry at about 60°C. The moisture content of the dry granules should be controlled below 1.5%. Sieve through a 20-mesh sieve, mix with magnesium stearate, and press into tablets.
