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. Norvasc: L'amlodipine bloque sélectivement les canaux calciques de type L du muscle lisse vasculaire, réduisant l'entrée transmembranaire de calcium et produisant une vasodilatation artérielle périphérique.
When Xalatan is preferred
