Statins have the effect of lowering LDL and total cholesterol, in addition to stabilizing plaque, improving endothelial function and preventing the progression of atherosclerosis. These drugs are not recommended to be taken every other day, but rather to be taken daily by patients to truly prevent the progression of atherosclerosis. If taken every other day, the stability of the blood concentration will be destroyed, and it will be relatively difficult to control the patient’s blood lipids within the ideal range, which is not only a waste of money but also cannot achieve the expected effect. Patients are advised to take it once a day, preferably at night before going to bed, for the best effect, or at any time of the day for statins like atorvastatin or resorvastatin.
