Prometrium vs Progesterone: are they the same?
Prometrium is a commercial brand whose active ingredient is exactly Progesterone. 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 — Prometrium contains Progesterone as its active ingredient. Talking about "Prometrium" in clinical terms is the same as talking about Progesterone at the dose strengths 100mg, 200mg. The differences from the authorised generic are brand, manufacturer (Catalent / Virtus), excipients, tablet appearance and price — not the active molecule itself.
When Prometrium is used
프로메트리움은 에스트로겐을 투여받는 폐경 후 여성의 자궁내막 보호, 이차 무월경 및 선택된 보조생식술 적응증에 승인되어 있습니다. 오프라벨 사용에는 월경전 불쾌장애, 폐경전후기 증상 및 선택된 환자의 수면 보조가 포함됩니다. 현 폐경 가이드라인에 따르면 미세화 프로게스테론은 호르몬 대체 요법에서 선호되는 프로게스토겐이며, 특히 심혈관 위험 인자나 편두통이 있는 여성에게 그렇습니다.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 프로메트리움의 프로게스테론은 프로게스테론 수용체에 결합하고 생식 및 기타 조직에서 유전자 발현을 조절합니다.
Brand or generic — which to choose?
For most patients, authorised generics of Progesterone are clinically equivalent substitutes for Prometrium 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.
