[0031] Example 1 prescription and preparation process

[0032]

[0033] Preparation:

[0034] 1) Weigh the main drug and various auxiliary materials required for the prescription, and pass the main drug through a 100-mesh sieve for use;

[0035] 2) Take a prescription amount of polyethylene glycol and heat it to 50~60℃ to make it into a molten liquid;

[0036] 3) Under slow stirring, add the prescription amount of dabigatran etexilate mesylate and 40% of the prescription amount of disintegrant in batches. After the addition is complete, stir slowly for 15~30min, and stir vigorously for 30~60min to disintegrate the drug. The solution is evenly dispersed. The speed of slow stirring is 150~300 rpm, and the speed of vigorous stirring is 5000~10000 rpm;

[0037] 4) Place the molten liquid prepared in step 3) under -20°C and rapidly cool down and solidify for 2~3 hours to obtain a solidified product;

Abstract

The invention provides a dabigatran etexilate mesylate oral solid preparation. With a specification of 110mg (based on free dabigatran etexilate), each tablet of the dabigatran etexilate mesylate oral solid preparation comprises the following components: 127mg of dabigatran etexilate mesylate (110mg of dabigatran etexilate), 180-190mg of water-soluble polymer, 15-20mg of disintegrant and 3.0-5.0mg of lubricant. According to the solid medicinal preparation provided by the invention, main drugs are dispersed in a water-soluble carrier, thus the dissolution rate of the preparation is increased, and the drug content uniformity is guaranteed. The dabigatran etexilate mesylate oral solid preparation provided by the invention is simple in preparation technology and suitable for industrial production.
