Mechanism and action
Xalatan: Le latanoprost est un promédicament de type ester, hydrolysé par les estérases cornéennes en son acide libre actif, qui se lie sélectivement au récepteur FP des prostaglandines. Claritin: La loratadine bloque sélectivement les récepteurs H1 périphériques de l'histamine, antagonisant ses effets lors des réactions allergiques.
