Description

Simvastatin capsule and preparation method thereof
Technical Field
The application relates to the technical field of medicines, in particular to a simvastatin capsule and a preparation method thereof.
Background
With the continuous development of society, the living standard and working rhythm of people are increasing, patients with cardiovascular and cerebrovascular diseases are increasing, and the cardiovascular and cerebrovascular diseases are also called "hypertension, hyperlipidemia and hyperglycemia" of "riches and honour disease", which refer to diseases of heart ischemia or hemorrhage caused by the sclerosis of heart and artery blood vessels, and comprise symptoms of coronary heart disease, angina pectoris, hypertension, arrhythmia, myocardial infarction, cerebral infarction and the like. Cardiovascular and cerebrovascular diseases are always threatening the health of human beings, and hypertension, hyperlipidemia, coronary heart disease and diabetes become epidemic of the times.
According to statistics, 40-45% of people over 60 years old suffer from hypertension and hyperglycemia or hyperlipidemia, and about 50% of diabetes patients are complicated with various senile diseases such as hypertension and hyperlipidemia. The cardiovascular and cerebrovascular diseases have the characteristics of high morbidity, high disability rate, high mortality, high recurrence rate and more complications, namely high morbidity, high morbidity and high mortality, the first onset age of patients with the cardiovascular and cerebrovascular diseases is below 60 years old, the morbidity of the patients with the cardiovascular and cerebrovascular diseases is 13.6 percent, and the patients with the cardiovascular and cerebrovascular diseases are gradually increased at the speed of twenty thousand persons every day; the death rate is up to 45 percent and accounts for 50 percent of the total death number; the disability rate of patients with cerebral apoplexy is up to 75 percent, and patients with coronary heart disease become half-labor; the recurrence rate is high and the recurrence rate of cardiovascular and cerebrovascular diseases (myocardial infarction and cerebral infarction) is as high as 42 percent within five years; many diseases of respiratory system, digestive system, urinary system, etc. are caused by cardiovascular and cerebrovascular accidents. Hyperlipidemia is one of representative diseases of cardiovascular and cerebrovascular diseases.
Hyperlipidemia is a common disease, and is a high incidence among the middle-aged and elderly people, and in recent years, the disease begins to be "favored" by a young white-collar family. The blood fat is too high, which easily causes 'blood viscosity', deposits on the vessel wall and forms atherosclerosis. These deposits build up and grow, gradually blocking the blood vessels, slowing blood flow, and in severe cases, blood flow is interrupted. This condition, if it occurs in the heart, causes coronary heart disease; if it occurs in the kidney, it causes renal arteriosclerosis and renal failure; when it occurs in the lower limbs, symptoms such as necrosis and ulceration of the limbs occur. In addition, hyperlipidemia can cause hypertension, induce gallstone and pancreatitis, and aggravate hepatitis, leading to male sexual dysfunction and senile dementia. Therefore, hyperlipidemia is not only a little higher problem of blood lipid, and its severity cannot be ignored absolutely.
Simvastatin is an HMG-COA (β -hydroxy and β -methyl-glutaryl-COA) reductase inhibitor that reduces cholesterol biosynthesis and regulates blood lipids by competitively inhibiting an early rate-limiting enzyme (HMG-COA reductase) in cholesterol anabolism. Simvastatin can reduce the content of Total Cholesterol (TC), low-density lipoprotein (LDL-C) and very low-density lipoprotein cholesterol (VLDC-C), slightly increase high-density lipoprotein cholesterol (HDL-C) and reduce plasma Triglyceride (TG), simvastatin has high selectivity to liver after being orally taken, the concentration of simvastatin in liver is obviously higher than that of other non-target tissues, most of simvastatin is absorbed by liver tissues and converted into an active metabolite, namely an e-hydroxy acid structure, can reduce the synthesis of liver cholesterol and regulate low-density lipoprotein receptor, promotes the clearance of low-density lipoprotein to reduce the level of intracellular cholesterol, reduces the level of moderate serum triglyceride and increases the level of blood high-density lipoprotein, and mainly plays a role in the liver and is then excreted from bile. Simvastatin has the advantages of strong pertinence, obvious curative effect, small toxic and side effects, good tolerance and the like, and is one of the best medicines for treating hypercholesterolemia.
Currently, the simvastatin capsule sold in the market has the problem of large individual dissolution difference, the auxiliary material is magnesium stearate which is used as a lubricant, and due to the hydrophobic property of the magnesium stearate, the dissolution rate of the simvastatin capsule can be reduced, so that the requirement of people cannot be met.
