Two lipid-lowering injections a year are useful. Lipid-lowering injection is a new type of lipid-lowering drug, which can effectively lower the body’s cholesterol and LDL levels, and is more convenient and simpler than oral medication, with higher patient compliance. Hyperlipidemia is a major risk factor for cardiovascular and cerebrovascular diseases and atherosclerosis, and usually patients need to take medication for life to lower body cholesterol or LDL levels. With the development of medical science and technology, lipid-lowering drugs have gradually risen from oral preparations, to injections. This new type of lipid-lowering injections, also known as PCSK9 (9th member of the Kexin-like pre-translational enzyme Bacillus subtilis protease family) inhibitors, promotes the body’s production of proteins that help to regulate cholesterol levels and control the number of LDL receptors, significantly lowering LDL cholesterol, and can also be used to lower LDL further on top of statin drugs. Lipid-lowering injections are mainly used to treat hyperlipidemia, not preventive medicine, allergic patients should not be used, the specific use of drugs need to follow the doctor’s instructions.
