Yasmin vs Ethinyl Estradiol: are they the same?
Yasmin is a commercial brand whose active ingredient is exactly Ethinyl Estradiol. 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 — Yasmin contains Ethinyl Estradiol as its active ingredient. Talking about "Yasmin" in clinical terms is the same as talking about Ethinyl Estradiol at the dose strengths 3mg / 0.03mg. The differences from the authorised generic are brand, manufacturer (Bayer), excipients, tablet appearance and price — not the active molecule itself.
When Yasmin is used
ヤスミンは配合経口避妊薬を選択する女性の妊娠予防に承認されています。低用量のヤーズはドロスピレノンの抗アンドロゲン活性に基づき、月経前不快気分障害および中等度のニキビに対する追加のFDA承認を持ちます。ヤスミンとヤーズは、抗ミネラルコルチコイド(体液貯留の軽減)または抗アンドロゲンプロファイル(ニキビ、多毛のコントロール)が好まれる場合に通常選択されますが、従来のレボノルゲストレル含有ピルよりもVTEリスクがわずかに高いことが知られています。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: ヤスミンは2つの補完的なメカニズムを組み合わせます。エチニルエストラジオールとドロスピレノンが共にLHとFSHを抑制し排卵を防止します。また子宮頸管粘液を肥厚化させ子宮内膜を菲薄化することで追加的な避妊バックアップを提供します。ドロスピレノンの抗ミネラルコルチコイド作用はナトリウムと水分の排泄をわずかに増加させ、従来のピルと比較して体液貯留が少なく体重が安定する傾向があります。抗アンドロゲン作用は数か月かけてニキビと多毛を改善する可能性…
Brand or generic — which to choose?
For most patients, authorised generics of Ethinyl Estradiol are clinically equivalent substitutes for Yasmin 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.
