Liraglutide

Status

FDA-approved. Approved since 2010 (Victoza, type 2 diabetes) and 2014 (Saxenda, weight management).

What it is

The once-daily injection that started the modern GLP-1 era — a modified GLP-1 peptide requiring daily dosing because it survives about 13 hours, not a week. Semaglutide is essentially its longer-acting successor.
