Crestor vs Rosuvastatin: are they the same?
Crestor is a commercial brand whose active ingredient is exactly Rosuvastatin. 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 — Crestor contains Rosuvastatin as its active ingredient. Talking about "Crestor" in clinical terms is the same as talking about Rosuvastatin at the dose strengths 5mg, 10mg, 20mg, 40mg. The differences from the authorised generic are brand, manufacturer (AstraZeneca), excipients, tablet appearance and price — not the active molecule itself.
When Crestor is used
Crestor est autorisé chez l'adulte dans le traitement de l'hypercholestérolémie primaire et de la dyslipidémie mixte, dans la prévention des événements cardiovasculaires chez les patients à risque élevé et en prévention secondaire.
Mechanisms compared

Brand or generic — which to choose?
For most patients, authorised generics of Rosuvastatin are clinically equivalent substitutes for Crestor 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.
