Trulicity vs Dulaglutide: are they the same?
Trulicity is a commercial brand whose active ingredient is exactly Dulaglutide. 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 — Trulicity contains Dulaglutide as its active ingredient. Talking about "Trulicity" in clinical terms is the same as talking about Dulaglutide at the dose strengths 0.75mg, 1.5mg, 3mg, 4.5mg. The differences from the authorised generic are brand, manufacturer (Eli Lilly), excipients, tablet appearance and price — not the active molecule itself.
When Trulicity is used
本剤は成人2型糖尿病において、単独または他の抗糖尿病薬との併用で血糖コントロールを改善する用途で適応があります。一部の市場では、確立された心血管疾患または複数のリスク因子を有する成人2型糖尿病患者において主要心血管イベントのリスクを低減する用途も適応となっています。トルリシティは1型糖尿病、糖尿病性ケトアシドーシス、または認められた適応のない人の美容目的の体重減少には適応がありません。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 皮下注射後、デュラグルチドは徐々に吸収され、99%超がアルブミンに結合した状態で循環します。膵β細胞、α細胞、中枢神経系および腸管のGLP-1受容体に結合します。受容体の活性化により、グルコース依存性のインスリン分泌が促進され、不適切なグルカゴン分泌が抑制され、胃排出が遅延し、食欲が低下します。これらの複合作用により、内因性低血糖リスクなしに空腹時および食後血糖が低下し、多くの成人で中等度の体重減少が得られます。定常状態は週1回投与開始…
Brand or generic — which to choose?
For most patients, authorised generics of Dulaglutide are clinically equivalent substitutes for Trulicity 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.
