Mechanisms compared
Zyrtec: Cetirizin blockiert selektiv periphere H1-Histaminrezeptoren und antagonisiert so die Wirkungen von Histamin, das von Mastzellen während allergischer Reaktionen freigesetzt wird. Gabapentin: Gabapentin ist ein strukturelles Analogon der Gamma-Aminobuttersäure (GABA), bindet jedoch nicht an GABA-Rezeptoren.
