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
크레스토는 성인의 1차 고콜레스테롤혈증 및 혼합 이상지질혈증 치료, 위험이 높은 환자의 심혈관 사건 예방, 심혈관 사건의 2차 예방에 승인되었습니다. 일부 시장에서는 전문의 감독 하에 만 6세 이상 가족성 고콜레스테롤혈증 소아에서도 승인됩니다. 국제 진료 지침에 따르면, 용량 선택은 기본 위험과 LDL 목표에 따라 결정됩니다.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 로수바스타틴은 간 콜레스테롤 합성의 속도 제한 효소인 HMG-CoA 환원효소를 경쟁적으로 억제합니다. 세포 내 콜레스테롤 감소는 LDL 수용체를 상향 조절하고 순환 LDL 제거를 증가시킵니다. 내피 기능, 염증, 플라크 안정성에 대한 다면적 효과가 심혈관 보호에 기여합니다. 로수바스타틴은 다른 많은 스타틴보다 친수성이 높아 조직 분포와 부작용 프로필에 영향을 줄 수 있습니다.
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.
