Answer:
Drug-eluting stents (DES) are commonly used to prevent restenosis in coronary artery disease. These stents are coated with drugs that are slowly released into the arterial wall to prevent the growth of scar tissue that can lead to restenosis. Some of the drugs used in DES include paclitaxel, sirolimus, everolimus, zotarolimus, and biolimus. The choice of drug depends on several factors, including the patient's medical history, the type of stent used, and the extent of the coronary artery disease. It is important to note that the use of drug-eluting stents is just one aspect of a comprehensive treatment plan for coronary artery disease and patients should work closely with their healthcare provider to determine the best course of treatment for their specific condition.
