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
Cialis ist bei erwachsenen Männern zur Behandlung der erektilen Dysfunktion indiziert.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: Während der sexuellen Stimulation wird im Corpus cavernosum Stickstoffmonoxid freigesetzt, das ein Enzym aktiviert, welches zyklisches GMP produziert.
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.
