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
본 약은 제2형 당뇨병 성인 환자에서 단독 또는 인슐린을 포함한 다른 항당뇨제와 병용하는 1차 경구 치료제로 적응증이 있습니다. 일부 시장에서는 10세 이상 청소년에서도 사용됩니다. 전문의 감독하에 다낭성난소증후군 및 당뇨병 전 단계에서 적응증 외 또는 적응증 확장 사용이 이루어집니다. 국제 가이드라인에 따르면 금기가 없는 한 대부분의 제2형 당뇨병 성인에게 진단 시 메트포르민을 고려해야 합니다.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 메트포르민은 미토콘드리아 복합체 I 억제를 통해 간 포도당 생성을 감소시키고, 이로 인해 세포 내 AMP/ATP 비율이 상승하여 AMP 활성화 단백질 인산화효소가 활성화됩니다.
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.
