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. Lumigan: Le bimatoprost est un analogue des prostamides qui augmente l'écoulement de l'humeur aqueuse par le trabéculum et par la voie uvéosclérale, abaissant la pression intraoculaire.
