Wegovy vs Semaglutide: are they the same?
Wegovy is a commercial brand whose active ingredient is exactly Semaglutide. 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 — Wegovy contains Semaglutide as its active ingredient. Talking about "Wegovy" in clinical terms is the same as talking about Semaglutide at the dose strengths 0.25mg, 0.5mg, 1mg, 1.7mg, 2.4mg. The differences from the authorised generic are brand, manufacturer (Novo Nordisk), excipients, tablet appearance and price — not the active molecule itself.
When Wegovy is used
ウゴービは、肥満(BMI 30以上)または過体重(BMI 27以上)で高血圧、脂質異常症、2型糖尿病、閉塞性睡眠時無呼吸などの体重関連併存疾患を少なくとも1つ有する成人における慢性体重管理に対して、低カロリー食および身体活動の増加への補助療法として適応されます。複数の市場では、肥満のある12歳以上の青年にも承認されています。添付文書によれば、治療は臨床医が開始し監督する必要があります。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: ウゴービは中枢神経系および消化管のGLP-1受容体に作用し、食欲を減少させ、胃排出を遅らせ、満腹感を増加させます。膵臓ではグルコース依存性インスリン分泌を促進し、不適切なグルカゴン放出を抑制します。これらの複合効果により通常はカロリー摂取が減少し、数ヶ月にわたり臨床的に意味のある進行性の体重減少をもたらします。低カロリー食と身体活動の増加を含む生活習慣対策は治療計画の不可欠な要素です。
Brand or generic — which to choose?
For most patients, authorised generics of Semaglutide are clinically equivalent substitutes for Wegovy 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.
