Mechanism and action
Zyrtec: La cétirizine bloque sélectivement les récepteurs H1 périphériques de l'histamine, antagonisant les effets de l'histamine libérée par les mastocytes lors des réactions allergiques. Restoril: Le témazépam se lie au site benzodiazépine du récepteur GABA-A et renforce de façon allostérique la conductance chlorure inhibitrice.
