Mechanism and action
Caverject: L'alprostadil se lie aux récepteurs des prostaglandines E situés sur le muscle lisse du corps caverneux et déclenche, par la voie de l'AMP cyclique, un relâchement musculaire indépendant de la voie du monoxyde d'azote qu… 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.
