Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical preparation technology, specifically relating to an ezetimibe tablet and its preparation method. Background Technology

[0002] The information disclosed in this background section is intended only to enhance understanding of the overall background of the invention and is not necessarily to be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0003] Primary hypercholesterolemia (PHH) is a lipid metabolism disorder caused by genetic or environmental factors, primarily characterized by elevated plasma total cholesterol (TC) or low-density lipoprotein cholesterol (LDL-C). PHH has a serious impact on patients' health and quality of life, with the following harms: 1. Increased risk of cardiovascular disease: High cholesterol is one of the main risk factors for atherosclerosis, increasing the incidence and mortality of cardiovascular diseases such as heart disease and stroke. 2. Inducing fatty liver: Long-term high cholesterol can damage liver function, affecting the metabolic and excretory functions of hepatocytes through blood circulation, as well as the production and excretion of bile acids, leading to fatty liver and even serious diseases such as cirrhosis and liver cancer. 3. Affecting reproductive capacity: High cholesterol is related to the metabolism of sex hormones; long-term high cholesterol can affect the synthesis and metabolism of sex hormones, affecting sperm reproduction and maturation, ultimately impacting male fertility. 4. Damaging the kidneys: High cholesterol can cause the deposition of glomerulonephrine and other aggregates in the kidneys, leading to diseases such as nephritis and nephrotic syndrome. 5. Increased risk of malignant tumors: High cholesterol is associated with the development of malignant tumors such as colorectal cancer, breast cancer, and prostate cancer. Severe high cholesterol can increase the risk of developing these malignant tumors.

[0004] Ezetimibe, developed by a pharmaceutical company, is a lipid-lowering drug that received FDA approval in the United States several years ago. Clinically, it is mainly used to treat primary hypercholesterolemia and homozygous familial hypercholesterolemia. Its advantages are mainly reflected in the following aspects: 1. Inhibition of cholesterol absorption: Ezetimibe is a cholesterol absorption inhibitor that can attach to the edge of the small intestinal villi, inhibiting cholesterol absorption and thus reducing the transport of cholesterol from the small intestine to the liver, thereby reducing the amount of cholesterol stored in the liver. 2. Lowering blood lipid levels: By inhibiting cholesterol absorption, ezetimibe can lower the levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and apolipoprotein B in plasma, controlling blood lipids within the target range. 3. Prevention of complications: If primary hypercholesterolemia is not treated promptly and properly, it may lead to serious consequences such as coronary atherosclerotic heart disease, cerebrovascular disease, peripheral vascular disease, myocardial infarction, and cerebral infarction. Ezetimibe can reduce the risk of vascular blockage and play a role in preventing complications of hypercholesterolemia. 4. High safety profile: Ezetimibe has demonstrated a high safety profile in clinical applications with relatively few side effects.

[0005] However, ezetimibe also has drawbacks, such as low oral bioavailability, which affects its efficacy; it is easily decomposed by light, and ezetimibe will undergo chemical changes such as decomposition or oxidation under light, which will reduce the efficacy of the drug or produce harmful substances.

[0006] Chinese patent CN109718215A discloses an ezetimibe sheet composed of the following ingredients by weight percentage: 10% ezetimibe, 55-60% lactose, 15-20% microcrystalline cellulose, 4-8% croscarmellose sodium, 3-5% povidone K30, 2-3% sodium dodecyl sulfate, 0.5-1% magnesium stearate, and 0.5-1% micronized silica, which improves the dissolution of ezetimibe.

[0007] Chinese patent CN105213342A discloses an ezetimibe tablet composed of the following components: ezetimibe: 100-200g, lactose: 600-1200g, microcrystalline cellulose PH101: 50-100g, croscarmellose sodium: 50-100g, sodium dodecyl sulfate: 1-2g, polyvinylpyrrolidone K30: 2-4g, magnesium stearate: 0.5-1g, and wetting agent: 40-80g. This reduces the fluctuation in the dissolution rate of the ezetimibe tablet.

[0008] While existing technologies have addressed the issue of low ezetimibe dissolution to some extent, the problem of ezetimibe's easy decomposition upon exposure to light remains unresolved. Summary of the Invention

[0009] Overcoming the shortcomings of existing technologies, this invention improves the formulation and preparation process of ezetimibe tablets, solving the problems of easy decomposition of ezetimibe upon exposure to light and low dissolution in existing technologies, and provides an ezetimibe tablet with high stability and high dissolution.

[0010] The technical solution of the present invention is as follows: The first objective of this invention is to provide a formulation for ezetimibe tablets, comprising: ezetimibe, starch, dextrin, microcrystalline cellulose, neotame, and magnesium stearate.

[0011] In several embodiments, the formulation of the ezetimibe sheet is as follows: 10 parts by weight of Ezekiel 120-280 parts by weight of starch 30-60 parts by weight of dextrin 3-7 parts by weight of microcrystalline cellulose Neotame 0.1~1 part by weight Magnesium stearate 0.2~2 parts by weight.

[0012] In one embodiment, the formulation of the ezetimibe sheet is as follows: 10 parts by weight of Ezekiel 180 parts by weight of starch 45 parts by weight of dextrin 5 parts by weight of microcrystalline cellulose Neotame 0.3 parts by weight 1 part by weight of magnesium stearate.

[0013] In one embodiment, the formulation of the ezetimibe sheet is as follows: 10 parts by weight of Ezekiel 150 parts by weight of starch 35 parts by weight of dextrin 4 parts by weight of microcrystalline cellulose Neotame 0.2 parts by weight 0.6 parts by weight of magnesium stearate.

[0014] In one embodiment, the formulation of the ezetimibe sheet is as follows: 10 parts by weight of Ezekiel 230 parts by weight of starch 55 parts by weight of dextrin 6 parts by weight of microcrystalline cellulose Neotame 0.6 parts by weight 1.5 parts by weight of magnesium stearate.

[0015] A second objective of this invention is a method for preparing the above-mentioned ezetimibe sheet, the method comprising the following steps: (1) Mix ezetimibe, microcrystalline cellulose and neotame to make mixture A; (2) Mix the mixture A obtained in step (1) with an appropriate amount of purified water, granulate, dry, and granulate to obtain drug granules A; (3) Crush starch and dextrin, pass through an 80-mesh sieve, add an appropriate amount of water, mix, granulate, dry, and granulate to obtain drug granules B; (4) Mix drug A and drug B, add magnesium stearate, mix, compress into tablets, and obtain ezetimibe tablets.

[0016] Further, step (1) is: pulverize ezetimibe, microcrystalline cellulose and neotame together, pass through an 80-mesh sieve to make mixture A.

[0017] Furthermore, the temperature of the purified water in step (2) is 30℃~40℃.

[0018] Furthermore, the ezetimibe tablets are in the specification of 10mg.

[0019] In several embodiments, the ezetimibe tablets may also contain at least one of fenofibrate, gemfibrozil, cholestyramine, cimetidine, glipizide, lovastatin, pravastatin, atorvastatin, rosuvastatin, and fluvastatin for combination therapy.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention overcomes the defects of ezetimibe being easily decomposed and oxidized by light by improving the formulation of ezetimibe tablets, especially by adding a certain proportion of microcrystalline cellulose and neotame, and by improving the preparation method and adjusting the mixing order of excipients. It also solves the problems of unstable ezetimibe content and low dissolution in ezetimibe tablets, and provides an ezetimibe tablet with high dissolution and high stability.
