Norvasc and Celexa are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Norvasc belongs to Médicaments cardiovasculaires while Celexa belongs to Antidépresseurs. 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. Celexa: Le citalopram inhibe sélectivement le transporteur de recapture de la sérotonine, augmentant sa disponibilité synaptique avec une affinité limitée pour les transporteurs de la noradrénaline ou les autres récepteurs.
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 Celexa is preferred
Celexa est autorisé dans la dépression caractérisée.
