Vorapaxar

Vorapaxar is a new anti-platelet drug that is part of the PAR-1 antagonist family, a new class of anti-platelet drug. It functions by inhibiting thrombin-related platelet aggregation. This mechanism works by a different pathway than other anti-platelet medications such as P2Y12 inhibitors. Unlike many other medication, vorapaxar does not affect ADP-mediated platelet aggregation, coagulation parameters, or bleeding time.
