Statin refers to statin drugs, commonly including atorvastatin calcium tablets, etc. 10mg and 20mg differ in terms of lipid-lowering intensity and adverse effects. Statin 10mg and 20mg, with double the dose difference, belong to different specifications. With the gradual increase of the dose, the effect of the drug will be gradually enhanced. Clinically, for severe hyperlipidemia, or serious cardiovascular disease, you can choose a larger dose of statin treatment, which can effectively reduce blood lipids, stabilize plaque, and reduce the risk of cardiovascular and cerebrovascular disease. However, as the dose of the drug increases, the adverse effects of the drug will gradually increase, and the risk of hepatic impairment will gradually increase, and the incidence of other adverse effects, such as muscle aches and pains, and rhabdomyolysis will also be elevated. Patients with active liver as well as pregnant women need to avoid using this drug. When taking statin, choose the right dosage under the guidance of your doctor and avoid buying the drug blindly to avoid adverse reactions.
