Liraglutide

aka Victoza

GLP-1 / Metabolic

Mechanism

Liraglutide is an FDA-approved GLP-1 receptor agonist marketed as Victoza (type 2 diabetes, approved 2010) and Saxenda (chronic weight management, approved 2014). It was the first GLP-1 analog approved for obesity and carries an FDA boxed warning for the risk of thyroid C-cell tumors. Pediatric indications include type 2 diabetes in patients ≥10 years (Victoza) and obesity in patients ≥12 years with BMI ≥95th percentile (Saxenda).
