Mechanism and action
Restoril: Temazepam bindet an die Benzodiazepin-Bindungsstelle des GABA-A-Rezeptors und verstärkt allosterisch die hemmende Chloridleitfähigkeit. Zyrtec: Cetirizin blockiert selektiv periphere H1-Histaminrezeptoren und antagonisiert so die Wirkungen von Histamin, das von Mastzellen während allergischer Reaktionen freigesetzt wird.

When Zyrtec is preferred
