Singulair vs Montelukast: are they the same?
Singulair is a commercial brand whose active ingredient is exactly Montelukast. 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 — Singulair contains Montelukast as its active ingredient. Talking about "Singulair" in clinical terms is the same as talking about Montelukast at the dose strengths 4mg, 5mg, 10mg. The differences from the authorised generic are brand, manufacturer (Organon), excipients, tablet appearance and price — not the active molecule itself.
When Singulair is used
싱귤레어는 성인 및 소아의 천식 유지 치료(운동유발 기관지경련 포함)와 기존 치료가 불충분하거나 내약성이 없는 경우 계절성 및 통년성 알레르기 비염 치료에 승인되어 있습니다. 현재 가이드라인에 따르면 몬테루카스트는 대부분의 성인에서 천식 유지의 1차 치료제는 아니며 흡입 코르티코스테로이드가 선호되지만, 추가 약제로서 또는 흡입기를 올바르게 사용할 수 없는 환자에게 유용합니다.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 몬테루카스트는 비만세포와 호산구에서 방출되는 염증 매개체인 류코트리엔 C4, D4, E4의 작용을 매개하는 CysLT1 수용체를 선택적으로 차단합니다. 이 수용체를 차단함으로써 기관지 수축, 점막 부종, 기도 염증을 감소시킵니다. 이 약물은 히스타민이나 베타2 아드레날린 경로에 영향을 주지 않으므로 항히스타민제 및 베타 작용제와 상보적입니다.
Brand or generic — which to choose?
For most patients, authorised generics of Montelukast are clinically equivalent substitutes for Singulair 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.
