[Dual platelet inhibitors in intensive care units].

BACKGROUND: The introduction of clopidogrel was a milestone in the development of modern antiplatelet therapy. However, the shortcomings in the pharmacokinetics of clopidogrel have led to the development of alternative substances. CURRENT CONCEPT: The two new drugs prasugrel and ticagrelor were included in the current guidelines for the treatment of patients with acute coronary syndrome. These potent platelet inhibitors, however, are associated with an increased rate of bleeding events, which is of particular importance in critically ill patients. However, the new platelet inhibitors are less effective in patients with cardiogenic shock or patients treated with therapeutic hypothermia. FUTURE: Recent studies underscore the assessment of the net clinical benefit in patient management. Since there is only a thin line between efficacy and safety in critically ill patients, future studies for risk stratification of antiplatelet therapy in terms of personalized medicine are mandatory.
