Key differences
Glucophage belongs to Behandlung der Diabetes mellitus while Norvasc belongs to Herz-Kreislauf-Medikamente. 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
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. Norvasc: Amlodipin blockiert selektiv L-Typ-Calciumkanäle in der glatten Gefäßmuskulatur, reduziert den transmembranen Calciumeinstrom und bewirkt eine periphere arterielle Vasodilatation.
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.
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.
