Simvastatin tablets can be taken for a long time. This is because simvastatin, like other statins, is actually used to inhibit cholesterol synthesis and inhibit LDL, which has a sustained effect on stabilizing plaque. It has been clinically proven that long-term use of simvastatin can achieve good efficacy and reduce the occurrence of vascular events, including cerebral infarction, cardiac infarction and other vascular events. People may be concerned that their cholesterol or LDL has reached the standard after taking simvastatin, which should actually be continued as well. The cholesterol or LDL standard is only one of the purposes of simvastatin to regulate lipids. In addition to inhibiting cholesterol and lowering LDL, simvastatin also stabilizes plaque, inhibits the production of vascular inflammatory factors, and improves endothelial cell function, all of which are beneficial to the development of atherosclerotic plaque. Unless there are serious adverse reactions during the use of simvastatin, such as liver enzyme indexes elevated to three times the upper limit or severe allergies have developed, simvastatin should be taken consistently for a long period of time. Long-term use of simvastatin has also been shown to result in better clinical outcomes.
