Mechanism and action
Cialis: Lors de la stimulation sexuelle, du monoxyde d'azote est libéré dans le corps caverneux et active une enzyme qui produit du GMP cyclique. 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 Cialis is preferred

When Norvasc is preferred
Norvasc est autorisé chez l'adulte dans le traitement de l'hypertension artérielle essentielle et de l'angor stable chronique, ainsi que dans l'angor vasospastique (de Prinzmetal).
