Statins, also known as statins, are a class of prescription drugs. Once the medication is started, patients cannot stop it on their own, and the specific time to stop or reduce the dose needs to be strictly followed by the doctor. The side effects of statins are closely related to the dose of the drug, so patients should pay attention to their health condition and go to the hospital immediately when abnormalities occur. Statins are mainly used for the prevention and treatment of cardiovascular diseases, especially for patients with high cholesterol, and they need to be taken for a long time. Patients will control their lipid levels to a relatively stable state through continuous medication, so patients with cardiovascular disease cannot stop taking them on their own. Statins are inhibitors of hydroxymethylglutarate monoacyl coenzyme synthase, the rate-limiting enzyme of cholesterol formation. After discontinuation, cholesterol synthesis returns to normal levels and blood cholesterol levels return to pre-drug levels. If the blood lipids are elevated but there are no other cardiovascular diseases, after the blood lipids are stabilized, you can go to the hospital to consult your treating doctor whether you need to stop taking the medication; if you have coronary heart disease, atherosclerosis, diabetes, etc., you need to take it for a long time and generally cannot stop taking it. The side effects of statins mainly include liver damage and muscle damage. If patients have symptoms such as liver pain, muscle aches, weakness and cramps, they can go to the hospital in time to clarify whether they need to change the medication or reduce the dosage. In addition, during the medication period, patients should also pay attention to avoid drinking alcohol, minimize the consumption of grapes, grapefruit and other types of fruits that may react with statins, and pay attention to avoid taking other drugs without authorization to avoid affecting the efficacy of the drugs.
