Method for preparing high stripping-degree hautriwaic glipizide capsule

Abstract

The preparation method of metformin hydrochloride glipizide capsule includes the following steps: using 250-500 weight portions of metformin hydrochloride, sieving it by using sieve with 100 meshes, using 2.5 weight portions of glipizide, sieving it by using sieve with 200 meshes or pulverizing it to make its fineness greater than 200 meshes, then uniformly mixing the above-mentioned materials, using dilute ethyl alcohol solution of polyvidone as adhesive, making soft material, granulating by using sieve with 24 meshes, drying at 50-60deg.C, finishing granules by using sieve with 20 meshes, adding 1% of magnesium stearate and capsulizing so as to obtain the invented finished product.

Description

technical field [0001] The invention relates to a preparation method of metformin hydrochloride glipizide capsules with high dissolution rate, belonging to the field of pharmaceutical preparations. Background technique [0002] Diabetes mellitus is a common disease that affects human health and life. It is a clinical syndrome caused by the interaction of genetic and environmental factors. Due to the absolute or relative lack of insulin secretion and the decrease in the sensitivity of target tissue cells to insulin, it causes diabetes. , protein, water and electrolytes and a series of metabolic disorders, with high blood sugar as the main common clinical sign.

Problems solved by technology

[0008] Chinese patent CN1617728A discloses a "medicine preparation and method for anti-diabetes", which discloses that the dosage ratio of metformin and glipizide is between 1000:1 and 100:1, and the technical problem to be solved is glipizide The problem of uniform content, for this reason, it is prepared by the method of double-layer tablet, or the method of injecting into capsules in portions; therefore, its process is complicated and the cost is high

[0011] The contents disclosed in the above patent applications do not provide the dissolution index of the preparation, and the actual test results have not reached 75%. Therefore, it is necessary to provide a glipizide hydrochloride preparation with uniform drug dosage and high dissolution rate.
