Drug-eluting stents: A pharmacy management perspective


Current treatment options for acute coronary syndromes as well as chronic stable angina often include the use of percutaneous coronary intervention (PCI) with routine stenting. The clear benefits of stents have lead to their routine use for prevention of restenosis. However, the benefits of stenting demonstrated on some aspects of restenosis are compromised by the induction of restenosis by neointimal hyperplasia that is stimulated by standard bare metal stents. FDA has approved 2 drug-eluting stents (DES). DES create a local delivery system at the vascular site to reduce restenosis by neointimal hyperplasia. Multiple clinical trials have demonstrated the safety and efficacy of the use of DES. This article reviews the use of PCI in coronary artery disease, the evolution and pathophysiology of restenosis, and multiple aspects of DES technology. While DES may not be a direct pharmacy and therapeutics committee responsibility, committee members are being called upon to provide insights into pathway processes for medical technology review committees evaluating DES since these products contain a key pharmacologic component. There are also important adjunctive antiplatelet therapy protocols that need to be developed and adhered to in conjunction with DES in order to ensure optimal outcomes.
