Cialis vs Tadalafil: are they the same?
Cialis is a commercial brand whose active ingredient is exactly Tadalafil. 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 — Cialis contains Tadalafil as its active ingredient. Talking about "Cialis" in clinical terms is the same as talking about Tadalafil at the dose strengths 2.5mg, 5mg, 10mg, 20mg. The differences from the authorised generic are brand, manufacturer (Eli Lilly), excipients, tablet appearance and price — not the active molecule itself.
When Cialis is used
시알리스는 성인 남성의 발기부전 치료에 적응증이 있습니다. 또한 양성 전립선 비대증과 관련된 하부 요로 증상의 치료에 승인되어 있으며, 두 가지 적응증이 동시에 있는 경우에는 매일 5mg 제형을 사용합니다. 이 약은 여성, 소아 환자 또는 관련 진단이 없는 남성에게는 승인되지 않았습니다. 제조사 처방정보에 따르면 치료는 심혈관 적합성 및 현재 복용 약물의 평가 후 진행해야 합니다.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 성적 자극 시 음경해면체에서 산화질소가 방출되어 cGMP를 생성하는 효소를 활성화합니다.
Brand or generic — which to choose?
For most patients, authorised generics of Tadalafil are clinically equivalent substitutes for Cialis 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.

Why does Cialis cost more than generic Tadalafil? ▾
The price difference reflects originator development costs, brand recognition and competition among generic manufacturers. The molecule is identical; the cost is not.
