If patients have carotid atherosclerosis plaque and need to take medication for treatment, they should go to the hospital to clarify the size, area, location and whether the atherosclerotic plaque is stable. If the plaque belongs to unstable plaque, but the area is not large, no surgery is needed, but drugs are needed for long-term treatment, at this time, the drugs that can be taken orally are as follows: 1. Anti-platelet aggregation drugs, such as aspirin, clopidogrel, Tigretol, the trade names are usually BAY aspirin enteric coated tablets, Polivy, BELLINDA, etc. 2. Lipitor, Cortisone, etc. These drugs have the effect of stabilizing the atherosclerotic plaque. The above drugs need to be taken for a long time, for example, 1-2 months, but when taking them, liver function monitoring and coagulation monitoring should be carried out.
