Displaying 2 results of Vorapaxar Stable Isotopes Vorapaxar is an antiplatelet drug that prevents the formation of blood clots. It works by blocking the action of a protein called protease-activated receptor-1 (PAR-1), which is involved in the activation of platelets. Stable isotopes are non-radioactive forms of atoms that can be used in research to track the metabolism of drugs like Vorapaxar. By labeling Vorapaxar with stable isotopes, researchers can better understand how the drug is absorbed, distributed, metabolized, and excreted by the body. This information can help improve the effectiveness and safety of the drug.
