Key differences
Norvasc belongs to Médicaments cardiovasculaires while Levitra belongs to Dysfonction érectile. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
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. Levitra: Lors de la stimulation sexuelle, du monoxyde d'azote est libéré dans le corps caverneux et active une enzyme produisant du GMP cyclique, qui relâche le muscle lisse et augmente l'afflux sanguin nécessaire à l'érection.
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).
When Levitra is preferred
Levitra est indiqué chez l'homme adulte dans le traitement de la dysfonction érectile.
