[0018] Prescription Components and Functions of Atorvastatin Calcium Tablets

[0019]

[0020] Preparation Process:

[0021] 1. Take each raw and auxiliary material according to the prescription, and pass through a 100-mesh sieve;

[0022] 2. Preparation of adhesive: prepare an adhesive solution containing 2.4% w / w of Tween-80 and 3.0% w / w of highly substituted hydroxypropyl cellulose (viscosity range 6.0-10.0mpa.s);

[0023] 3. Mixing of raw and auxiliary materials: put microcrystalline cellulose pH101, atorvastatin calcium, internally added croscarmellose sodium, calcium carbonate, and lactose into the wet mixing granulator in sequence, and mix well;

[0024] 4. Granulation: put in binder solution, prepare soft material, and pass the soft material through a 20-mesh sieve;

[0025] 5. Drying: Put the wet granules in an oven and dry at 40°C to 60°C;

[0049] Experimental Example 2 Preparation of Atorvastatin Calcium Tablets Using Different Process Conditions

[0050] Atorvastatin calcium tablets were prepared according to the prescription and process of Example 1, and the two key process parameters of raw material micronization and granule drying temperature were investigated.

[0052]

[0053] Table 4 Comparison of quality test results of atorvastatin calcium tablets prepared under different process conditions

[0054]

[0055] After micronizing atorvastatin calcium, its particle size distribution is as follows: D(v, 0.10) 0.355μm, D(v, 0.50) 2.014μm, D(v, 0.90) 11.147μm, that is, the atorvastatin calcium used in this project The particle size of statin calcium raw materials is about 1300 mesh. Comparing prescriptions 7 and 8: the micronization of raw materials is beneficial to the dissolution of the drug (atorvastatin calcium, which belongs to BCS class II).

Abstract

The invention discloses an atorvastatin calcium tablet, which is prepared from the following raw and auxiliary materials in the weight ratio: 10-20 parts of atorvastatin calcium, 30-72 parts of calcium carbonate, microcrystalline cellulose pH 101 54-108 parts, 30-72 parts of lactose, 9-20.4 parts of croscarmellose sodium, 0.45-1.5 parts of polysorbate 80, 1.5-3 parts of high-substituted hydroxypropyl cellulose, 0.75 parts of magnesium stearate ~1.5 parts, Opadry YS‑1‑70404.5~15 parts. The inventor has fully considered the drug quality of atorvastatin calcium tablets and the simplicity of the production process, using a safe dose of alkaline pH agent calcium carbonate as a stabilizer, high-substituted hydroxypropyl cellulose aqueous solution as a binder, and wet granulation .

Description

technical field [0001] The invention relates to an atorvastatin calcium tablet and a preparation method thereof, belonging to the field of medicine. Background technique [0002] Atorvastatin is a novel β-hydroxy-β-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor for the treatment of hypercholesterolemia and coronary heart disease or the combination of predisposing factors such as coronary heart disease Patients with hypercholesterolemia or mixed dyslipidemia. It reduces plasma cholesterol and serum lipoprotein concentrations by inhibiting the synthesis of HMG-CoA reductase and cholesterol in the liver, and enhances the uptake and metabolism of LDL by increasing the number of hepatic low-density lipoprotein (LDL) receptors on the cell surface. Compared with other statin drugs, atorvastatin calcium tablets have a stronger inhibitory effect on HMG-CoA reductase, and have a wide range of indications; at the same time, the drug has the largest effect on reducing liver lo...
