Problems solved by technology

[0005] Invention patent CN103735529A discloses a method for preparing amoxicillin dry granulation capsules. Dry granulation is adopted, and cross-linked povidone is added as a disintegrant during the granulation process. The addition of cross-linked povidone will cause capsules There are large individual differences in dissolution. In addition, crospovidone may also reduce the solubilizing effect of the co-solvent, and increase the relative addition of the co-solvent in a disguised form.
[0006] Currently commercially available amoxicillin capsules are often added with disintegrants such as crospovidone and sodium carboxymethyl starch for granulation to achieve rapid disintegration and rapid dissolution, but there are high polymer impurities, poor stability, Problems such as sudden release of capsules and large differences in individual dissolution rates caused by uneven mixing of raw materials and disintegrants

Abstract

The invention discloses an amoxicillin capsule and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. The components contained in the amoxicillin capsule and their mass fractions are: 100 parts of amoxicillin, 0.1-1 part of sodium lauryl sulfate, 0.1-3 parts of talcum powder, and 0.25-2.0 parts of magnesium stearate. The present invention ensures the higher dissolution rate of amoxicillin by adjusting the particle size of raw material amoxicillin particles and the ratio of auxiliary materials, avoids the use of disintegrants such as sodium carboxymethyl starch and crospovidone, and reduces the amount of amoxicillin The volume of the amoxicillin capsule; the production and configuration steps of the medicine of the amoxicillin capsule are simplified, the production cost is reduced, the content of high molecular impurities in the amoxicillin capsule is reduced, and the production efficiency is improved.
