Avoid oral glycoprotein IIb/IIIa inhibitors. a

Why?

  • Patients with acute coronary syndrome or requiring urgent revascularisation who receive an oral glycoprotein IIb/IIIa inhibitor compared with aspirin are at increased risk of major bleeding and death, but are less likely to undergo urgent revascularisation. a
  • There is no clear effect on myocardial infarction. a

Oral glycoprotein IIb/ IIIa inhibitors increase death and major bleeding
