Glucophage vs Metformin: are they the same?
Glucophage is a commercial brand whose active ingredient is exactly Metformin. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Glucophage contains Metformin as its active ingredient. Talking about "Glucophage" in clinical terms is the same as talking about Metformin at the dose strengths 500mg, 850mg, 1000mg. The differences from the authorised generic are brand, manufacturer (Merck Serono), excipients, tablet appearance and price — not the active molecule itself.
When Glucophage is used
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.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 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.
Brand or generic — which to choose?
For most patients, authorised generics of Metformin are clinically equivalent substitutes for Glucophage and typically cost substantially less. The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
