Provera vs Medroxyprogesterone: are they the same?
Provera is a commercial brand whose active ingredient is exactly Medroxyprogesterone. 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 — Provera contains Medroxyprogesterone as its active ingredient. Talking about "Provera" in clinical terms is the same as talking about Medroxyprogesterone at the dose strengths 2.5mg, 5mg, 10mg. The differences from the authorised generic are brand, manufacturer (Pfizer), excipients, tablet appearance and price — not the active molecule itself.
When Provera is used
프로베라는 무월경, 호르몬 불균형으로 인한 비정상 자궁 출혈, 에스트로겐을 받는 폐경 후 여성의 자궁내막 증식증 예방에 승인되어 있습니다. 현재 폐경 가이드라인에 따르면 미세화 프로게스테론이 유방암 및 심혈관 위험이 더 낮다는 증거로 인해 HRT에서 일반적으로 MPA보다 선호되지만, 프로베라는 여전히 광범위하게 사용되며 효과적인 대안입니다.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 메드록시프로게스테론 아세테이트는 프로게스테론 수용체에 결합하여 강력한 황체기 효과를 생성합니다: 자궁경부 점액 농축, 배란 억제, 자궁내막 박화, HRT에서의 자궁내막 증식 감소.
Brand or generic — which to choose?
For most patients, authorised generics of Medroxyprogesterone are clinically equivalent substitutes for Provera 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.
