Why Liraglutide and Dulaglutide Aren’t Enough: The Search for a Better GLP-1 Solution

Why Liraglutide and Dulaglutide Aren’t Enough: The Search for a Better GLP-1 Solution

While liraglutide and dulaglutide have been mainstays in GLP-1 therapy, they often fall short compared to newer options like tirzepatide and semaglutide, particularly for weight loss. This post explores their limitations and the need for more effective GLP-1 solutions.

Liraglutide (Saxenda, Victoza): Limitations in Weight Loss

  • Efficacy: Liraglutide achieves 11-18 lbs weight loss over 52 weeks (5-7.8% body weight), significantly less than tirzepatide (33-46 lbs) and semaglutide (22-33 lbs).
  • Challenges:
    • Daily injections reduce patient adherence compared to weekly options.
    • Still in shortage (two presentations available, three limited as of December 19, 2024).
    • Gastrointestinal side effects (nausea, vomiting) are common.

Dulaglutide (Trulicity): Falling Short of Expectations

  • Efficacy: Dulaglutide achieves 11-15 lbs weight loss over 52 weeks (3-5% body weight), far below tirzepatide and semaglutide.
  • Challenges:
    • Weekly injection, but still in shortage (all presentations available per manufacturer, not FDA-resolved).
    • Lower weight loss efficacy and similar gastrointestinal side effects.

Patient Expectations and the Efficacy Gap

Many patients expect tirzepatide-like results (33-46 lbs), and liraglutide vs tirzepatide comparisons show a significant gap. Liraglutide and dulaglutide often lead to early plateaus, potentially causing dissatisfaction and prompting patients to seek alternatives.

The Need for Better GLP-1 Solutions

The limitations of liraglutide and dulaglutide highlight the need for innovative GLP-1 therapies that can deliver greater weight loss, improve adherence, and address side effects more effectively.
