Key differences
Norvasc belongs to Herz-Kreislauf-Medikamente while Glucophage belongs to Behandlung der Diabetes mellitus. 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: Amlodipin blockiert selektiv L-Typ-Calciumkanäle in der glatten Gefäßmuskulatur, reduziert den transmembranen Calciumeinstrom und bewirkt eine periphere arterielle Vasodilatation. Glucophage: Metformin senkt die hepatische Glukoseproduktion durch Hemmung des mitochondrialen Komplexes I, wodurch das zelluläre AMP/ATP-Verhältnis steigt und die AMP-aktivierte Proteinkinase aktiviert wird.
When Norvasc is preferred
Norvasc ist bei Erwachsenen zur Behandlung der essenziellen arteriellen Hypertonie und der chronischen stabilen Angina pectoris sowie der vasospastischen Angina pectoris (Prinzmetal-Angina) zugelassen.
When Glucophage is preferred
Das Arzneimittel ist als orale First-Line-Therapie bei Erwachsenen mit Diabetes mellitus Typ 2 indiziert, allein oder in Kombination mit anderen Antidiabetika einschließlich Insulin.
