A Snapshot on Clinical Trials on Zotarolimus DES: A Repurposing Drug against Myocardial Infarction.

Abstract

Myocardial infarction is the permanent death (necrosis) of heart muscle caused by a lack of oxygen for an extended period of time (ischemia). Since the very first percutaneous transluminal coronary angioplasty was done 40 years ago, the science of interventional cardiology has advanced dramatically. The above progression began with a balloon catheter attached to a fixed wire, advancing to bare-metal stents, first-generation drug-eluting stents (DES), second- and third-generation biodegradable polymer-based DES. Ultimately, bioabsorbable stents are still in development. Zotarolimus is a new pharmacologic therapy with a similar reprint address; for example, the antirestenosis agent sirolimus has recently been investigated as part of a stent platform combined with a biomimetic phosphorylcholine and BioLINX polymer for its biological activity, as well as its usefulness as an antiproliferative agent. Several clinical trials have been conducted to assess the safety and efficacy of the zotarolimus drug-eluting stent (Z-DES). Medtronic Medical Devices, a global leader in medical technology (United States), and Abbot Global Health Care and Research began clinical trials on the Z-DES in 2002 and will continue through 2021 (INDIA). Endeavor (E-Zes), Resolute (R-Zes), Resolute Integrity (I-Zes), and Resolute Onyx are the different forms of Z-DES that Medtronic has tested in clinical trials. In comparison to other DES, Z-DES was found to be safe in these clinical trials done across multiple nations and in a diverse demographic. This review helps understand the overall clinical trial of Z-DES.
