Priligy vs Dapoxetine: are they the same?
Priligy is a commercial brand whose active ingredient is exactly Dapoxetine. 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 — Priligy contains Dapoxetine as its active ingredient. Talking about "Priligy" in clinical terms is the same as talking about Dapoxetine at the dose strengths 30mg, 60mg. The differences from the authorised generic are brand, manufacturer (Menarini), excipients, tablet appearance and price — not the active molecule itself.
When Priligy is used
プリリジーは診断が確認された18歳から64歳の成人男性における早漏の頓用治療に適応されます。診断には通常、一貫して急速な射精(挿入後約1分以内)の個人歴、関連する個人的苦痛または対人関係の困難、および他の原因の不在が必要です。本剤は一般的な性的パフォーマンス向上、不安、うつ病、または女性の適応症には適応されません。添付文書によれば、治療は数回の試行後に評価されるべきです。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 射精は中枢神経系のセロトニン経路によって制御されます。セロトニンシグナル伝達の増加は射精反射を遅延させます。ダポキセチンはシナプス前ニューロンのセロトニントランスポーターを選択的に遮断し、シナプスのセロトニン濃度を上昇させます。その急速な動態—1時間で最高血漿濃度、約1.5時間の半減期—は、投与後1-3時間の期間に臨床的に有用な射精遅延をもたらします。臨床試験によれば、膣内射精潜時はプラセボに対して2-3倍に増加します。
Brand or generic — which to choose?
For most patients, authorised generics of Dapoxetine are clinically equivalent substitutes for Priligy 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.
