Norvasc vs Amlodipine: are they the same?
Norvasc is a commercial brand whose active ingredient is exactly Amlodipine. 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 — Norvasc contains Amlodipine as its active ingredient. Talking about "Norvasc" in clinical terms is the same as talking about Amlodipine at the dose strengths 2.5mg, 5mg, 10mg. The differences from the authorised generic are brand, manufacturer (Pfizer), excipients, tablet appearance and price — not the active molecule itself.
When Norvasc is used
노바스크는 성인의 본태성 고혈압 및 만성 안정형 협심증, 혈관경련성(프린즈메탈) 협심증의 치료에 승인되어 있습니다. 만 6세 이상의 소아 환자에서는 고혈압에 승인되어 있습니다. 노바스크는 단독 또는 ACE 억제제, 안지오텐신 수용체 차단제, 이뇨제, 베타차단제 등 다른 항고혈압제와 병용할 수 있습니다. 국제 가이드라인에 따라 칼슘 채널 차단제는 고혈압의 권장 1차 약물 계열 중 하나입니다.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 암로디핀은 혈관 평활근의 L형 칼슘 채널을 선택적으로 차단하여 막 통과 칼슘 유입을 감소시키고 말초 동맥 혈관 확장을 일으킵니다. 본 약물은 치료 용량에서 심근 수축력이나 방실 전도에 비교적 적은 직접적 영향을 미칩니다. 그 결과 전신 혈관 저항과 혈압이 지속적으로 감소하고, 관상동맥 관류가 동시에 개선되어 항협심증 효과가 뒷받침됩니다.
Brand or generic — which to choose?
For most patients, authorised generics of Amlodipine are clinically equivalent substitutes for Norvasc 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 Norvasc cost more than generic Amlodipine? ▾
The price difference reflects originator development costs, brand recognition and competition among generic manufacturers. The molecule is identical; the cost is not.
