Tirzepatide as Compared with Semaglutide for the Treatment of Obesity (SURMOUNT-5)
結論：At 72 weeks tirzepatide produced significantly greater weight loss than semaglutide: -20.2% vs -13.7% (P<0.001), a ~6.5-percentage-point superiority in adults with obesity but without diabetes.

結論：At 72 weeks dose-dependent weight loss of -15.0% (5mg), -19.5% (10mg) and -20.9% (15mg) vs -3.1% placebo (P<0.001 all); 85-91% of tirzepatide patients lost >=5% vs 35% placebo.

結論：Across ~5,800 patients tirzepatide lowered weight by MD -12.47 kg vs placebo and modestly outperformed semaglutide (MD -1.90 kg, 95% CI -2.97 to -0.83); 78%/56%/32% reached >=5%/>=10%/>=15% loss.
前往 PubMed Tirzepatide as a novel effective and safe strategy for treating obesity: a systematic review and meta-analysis of randomized controlled trials

PTT MuscleBeach 板網友分享猛健樂 (Tirzepatide) 減重 3.5 個月降 6 公斤、肝指數 GPT 同步改善，並從 2.5mg 加量至 3.75mg；多數討論為支持態度。台灣食藥署 2023 年僅核准 Mounjaro 用於第二型糖尿病，減重屬「仿單外使用 (off-label)」；同藥廠減重專用品牌 Zepbound 在美國 FDA 為 ON-LABEL 但台灣尚未上市，社群常與 Wegovy/週纖達混為一談。
💬社群實感
多數正面
破解迷思 社群最常見的 5 個誤解
✓
事實誤以為「猛健樂」與「Wegovy/週纖達」是同一支藥，實際上猛健樂是 Tirzepatide (GLP-1+GIP 雙效)，Wegovy 是 Semaglutide (單一 GLP-1)
✓
事實誤以為 Mounjaro 與 Zepbound 是不同藥物，實際上同為 Tirzepatide，只是 Zepbound 為美國 FDA 減重專用品牌；台灣目前只有 Mounjaro
✓
事實誤以為猛健樂在台灣已核准減重適應症，實際上 TFDA 僅核准第二型糖尿病，減重為 off-label
✓
事實誤以為「停藥就會立刻復胖」，臨床上若無維持飲食運動確實易復胖，但搭配生活型態調整可降低反彈幅度
✓
事實誤以為劑量越高瘦越快越好，實則加量過快會放大噁心嘔吐風險，多數醫師建議逐步階梯加量
🩹 社群通報的副作用
- 噁心、嘔吐 (前 2 週與加量期最明顯)
- 腹瀉與便祕交替
- 打完 24-48 小時內疲倦想睡
- 吃太飽或油膩食物易脹氣打嗝
- 少數反映掉髮與「猛健樂臉」(快速消瘦導致臉部凹陷)
