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. Lexapro: Lexapro agit en inhibant sélectivement le transporteur de recapture de la sérotonine (SERT) au niveau de la synapse, augmentant la disponibilité de la sérotonine pour les récepteurs postsynaptiques.
