Fluvastatin belongs to the statin class of lipid-lowering drugs and can be taken on a long-term basis. Fluvastatin inhibits cholesterol synthesis by inhibiting the rate-limiting enzyme in the process of cholesterol synthesis, thus lowering the cholesterol level in the blood. Therefore, fluvastatin is mainly used for hypercholesterolemia and mixed hyperlipidemia with mainly elevated cholesterol, and it can raise HDL cholesterol, which can be used for anti-atherosclerosis treatment of cardiovascular and cerebrovascular diseases. The most important side effects of fluvastatin are muscle pain and weakness, and in severe cases, rhabdomyolysis can occur, leading to liver and kidney function damage and the possibility of inducing diabetes. Therefore, during the use of fluvastatin, attention should be paid to regular monitoring of liver and kidney function, blood glucose and muscle enzyme profiles to avoid serious side effects.
