Key differences
Ventolin belongs to Médicaments respiratoires while Norvasc belongs to Médicaments cardiovasculaires. 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
Ventolin: Le salbutamol active sélectivement les récepteurs bêta-2 adrénergiques du muscle lisse bronchique, entraînant un relâchement des voies aériennes et une bronchodilatation rapide en cinq à quinze minutes. 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 Ventolin is preferred
Ventolin est autorisé chez l'adulte et l'enfant pour lever le bronchospasme dans l'asthme et l'obstruction bronchique réversible de la bronchopneumopathie chronique obstructive.
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).
