verdict
Liraglutide has direct obesity, diabetes, cardiovascular, and adolescent evidence, with daily dosing and product-specific labels.
if you are comparing Saxenda and Victoza: Both contain liraglutide and use once-daily subcutaneous prefilled pens. Saxenda is the weight-management product; Victoza is the type 2 diabetes product with a cardiovascular-risk indication.
if you are comparing it with semaglutide: STEP 8 directly compared weekly semaglutide with daily liraglutide in 338 adults without diabetes. Mean weight change at 68 weeks was -15.8 percent versus -6.4 percent.
if you are asking why it still matters: SCALE established adult obesity efficacy, LEADER established cardiovascular benefit in high-risk type 2 diabetes, and a randomized trial established an adolescent obesity evidence base.
This is an evidence record, not a dosing recommendation.
