They belong to different therapeutic classes and are chosen for different indications.

Mechanisms compared
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.
