Addyi vs Flibanserin: are they the same?
Addyi is a commercial brand whose active ingredient is exactly Flibanserin. 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 — Addyi contains Flibanserin as its active ingredient. Talking about "Addyi" in clinical terms is the same as talking about Flibanserin at the dose strengths 100mg. The differences from the authorised generic are brand, manufacturer (Sprout Pharmaceuticals), excipients, tablet appearance and price — not the active molecule itself.
When Addyi is used
アディは閉経前女性の後天性、全般性の性的欲求低下障害(HSDD)の治療に適応されます。診断には性欲低下に伴う個人的苦痛が必要であり、他の医学的または精神医学的疾患、人間関係の問題、薬剤の副作用などでよりよく説明されないものとされています。アディは閉経後女性、男性、他の同定可能な原因による性的問題には承認されていません。添付文書によれば治療有効性は8週後に評価し、臨床的改善がない場合は中止すべきとされています。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 性欲はセロトニン(一般に抑制性)、ドパミンおよびノルアドレナリン(一般に興奮性)が関与する複雑な中枢神経系経路により調節されます。フリバンセリンは5-HT1A受容体作動薬および5-HT2A受容体拮抗薬として作用し、皮質領域でドパミンおよびノルアドレナリン伝達を促進する付加的作用を持ちます。毎日投与を数週間続けることでバランスが性欲側に傾くと考えられています。発現は緩徐で、添付文書によれば通常8週間の連続使用後に完全な効果が評価されます。
Brand or generic — which to choose?
For most patients, authorised generics of Flibanserin are clinically equivalent substitutes for Addyi 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.
