Recently a novel, intravenous P2Y12 inhibitor - cangrelor - has been released. Cangrelor enables immediate inhibition of the platelet P2Y12 inhibitor. The drug has a short half-life, is reversible and is only effective during administration (7). This contrasts with the available oral P2Y12 inhibitors, which all induce inhibition of the platelets for several days. Although ticagrelor is reversible, the platelet inhibition induced by this widely used, potent drug lasts for at least 3 days (8). The effects of cangrelor on platelet inhibition and clinical outcome have been documented in three, large clinical randomized trials (9-11).
