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.
