Liraglutide

Acylated GLP-1 analog with 97% homology to native human GLP-1. The C16 fatty acid chain enables albumin binding, extending duration from the native peptide’s 2-minute half-life to 13 hours. Activates GLP-1 receptors in the pancreas (insulin secretion, glucagon suppression), hypothalamus (satiety), and gastrointestinal tract (delayed gastric emptying).

Notes

Liraglutide is the first-generation proof of concept. Daily dosing at 3.0mg for obesity. ~8% body weight reduction in SCALE — meaningful in 2015, modest by 2024 standards. LEADER demonstrated cardiovascular benefit, which opened the door for semaglutide’s SELECT trial. The 13-hour half-life means daily injections, which means compliance friction, which means real-world results trail behind clinical data. Semaglutide displaced it for the same reason cypionate displaced propionate — pharmacokinetics that match human behavior. But liraglutide still has a role. It clears fast. If you develop pancreatitis or intolerable GI effects, you want the drug out of your system in 48 hours, not 5 weeks.
