Key differences
Norvasc belongs to Médicaments cardiovasculaires while Glucophage belongs to Traitement du diabète. 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. Glucophage: La metformine réduit la production hépatique de glucose en inhibant le complexe I mitochondrial, ce qui élève le rapport AMP/ATP cellulaire et active l'AMP-kinase.
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 Glucophage is preferred
Le médicament est indiqué en traitement oral de première intention chez l'adulte atteint de diabète de type 2, seul ou en association à d'autres antidiabétiques, dont l'insuline.
