Mechanisms compared
Zyrtec: Cetirizin blockiert selektiv periphere H1-Histaminrezeptoren und antagonisiert so die Wirkungen von Histamin, das von Mastzellen während allergischer Reaktionen freigesetzt wird. Clopidogrel: Clopidogrel selbst ist inaktiv; der aktive Metabolit, der in der Leber durch CYP2C19 und andere Cytochrome gebildet wird, bindet irreversibel an den P2Y12-ADP-Rezeptor auf Thrombozyten.
