Mechanism and action
Zyrtec: Cetirizin blockiert selektiv periphere H1-Histaminrezeptoren und antagonisiert so die Wirkungen von Histamin, das von Mastzellen während allergischer Reaktionen freigesetzt wird. Wellbutrin: Wellbutrin hemmt die Wiederaufnahme von Noradrenalin und Dopamin, mit deutlich schwächerer Wirkung auf Serotonin.
