Key differences
Norvasc belongs to Médicaments cardiovasculaires while Xanax belongs to Anxiolytiques. 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. Xanax: L'alprazolam se lie au site benzodiazépine du récepteur GABA-A et renforce de façon allostérique la conductance chlorure médiée par le GABA, hyperpolarisant les neurones du système nerveux central.
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 Xanax is preferred
Xanax est autorisé chez l'adulte dans la prise en charge de courte durée du trouble anxieux généralisé et du trouble panique avec ou sans agoraphobie.
