“…The use of drugs to coat stents drastically reduces the process of re-stenosis [14,15]. Its expandable metal composition, whether coated with any drug or not, has a structure comprising a metal core of cobalt–chromium alloy or stainless steel and on the outside may have a coating of two polymers, lactic acid-co-glycolic acid (PLGA) or polylactic acid (PLA) that, in turn, can be manipulated to have additional drugs or antibodies integrated [16,17,18]. Some of the most commonly used drugs in stents are immunosuppressants, such as sirulimus, to reduce the risk of stent thrombosis caused by cell rejection [17].…”
