Rosuvastatin calcium tablets can be used to treat hyperlipidemia. This drug not only lowers LDL cholesterol and total cholesterol, but also raises HDL, making it one of the secondary prevention drugs in cardiovascular diseases. In addition to lowering lipids, it also stabilizes plaque, is anti-inflammatory, and improves vascular endothelial function. For patients with angina pectoris and cerebral infarction, it needs to be taken orally for a lifetime and for a long time in order to help better prevent the progression of the disease. Some patients are not high in lipids, but they are also recommended to take it for a long time so as to help prevent the progression of the disease. However, attention must be paid to regular review of liver function, cardiac enzymes, and kidney function when applying this drug, and for patients with renal insufficiency, attention should be paid to adjusting the dose of the drug administered. Also, if a patient develops rhabdomyolysis or myalgia during the course of the drug, this drug needs to be stopped. If there is only a mild increase in transaminases, it is often not necessary to discontinue the drug or to reduce the dose of the drug taken, and regular observation is sufficient.
