Also called: PF-07976016 and Liraglutide, Liraglutide and Exercise, Oral Liraglutide Multi-Excipient System
Liraglutide is a medicine that copies a natural body signal called GLP-1. It belongs to a group of drugs called GLP-1 medicines. Doctors give it to people with type 2 diabetes and to people who need help losing weight. It works by copying a gut hormone that comes out after you eat.
This helps the body make insulin, slows down how fast food leaves the stomach, and makes you feel full sooner. It is given as a daily shot. Studies show it helps lower blood sugar and helps with weight loss. Newer research suggests these medicines may do more than help with sugar and weight.
In one big study, liraglutide was given to more than 2,600 people with asthma or lung disease, and people taking GLP-1 medicines had fewer breathing flare-ups than people taking older diabetes pills. Other studies suggest benefits for gut and mental health problems too. But much of this research is very new and still being checked. Liraglutide is a real prescription drug, so it should only be used with a doctor's care.

SubQ
mg vs mcg: one milligram (mg) equals 1,000 micrograms (mcg) — multiply by 1,000 going from mg to mcg, divide by 1,000 going from mcg to mg. Mixing the two up is a thousand-fold dosing error: 1 mg taken instead of 1 mcg is a 1,000× overdose; 1 mcg instead of 1 mg is a 1,000× underdose. Always double-check the unit label and the decimal place.

News
Dated, sourced reporting that mentions Liraglutide.
Novo Nordisk announced topline results showing CagriSema, a fixed-dose combination of cagrilintide and semaglutide, produced greater weight loss than tirzepatide in adults with type 2 diabetes in the REIMAGINE 5 trial (12.4% vs. 9.1% at 60 weeks), while achieving noninferior HbA1c reductions. In the REDEFINE 9 trial, CagriSema led to 21% weight loss at 68 weeks in adults with overweight or obesity without diabetes. These are topline company-announced results from ongoing trial programs.
A new analysis of the SELECT trial published in JAMA Cardiology found that semaglutide 2.4 mg (Wegovy) delivered cardiovascular benefits versus placebo consistently across all frailty levels. The most frail patients experienced the greatest quality-of-life improvements. The findings address concerns that GLP-1 therapies may be less safe or effective in frail populations.
An abstract presented at the 2026 European Respiratory Society International Congress links semaglutide use in patients with type 2 diabetes to fewer exacerbations in asthma (38% reduction) and COPD (21% reduction). Other GLP-1 receptor agonists like exenatide and dulaglutide also showed exacerbation reductions. The associations persisted regardless of weight or glycemic changes, suggesting possible direct lung anti-inflammatory effects.
Law firm Parker Waichman LLP has filed multiple lawsuits alleging patients developed NAION, an irreversible eye condition causing permanent vision loss, after taking Novo Nordisk's semaglutide drugs Ozempic and Wegovy. The lawsuits cite research linking semaglutide to increased NAION risk. The litigation alleges the manufacturer failed to adequately warn about the eye-injury risk.
The American College of Physicians has issued a new clinical guideline naming semaglutide (Wegovy, Ozempic) and tirzepatide (Zepbound, Mounjaro) as preferred first-line drug treatments for adults with obesity, used alongside lifestyle changes. The recommendations were published in Annals of Internal Medicine and ranked other options like phentermine-topiramate, liraglutide, and naltrexone-bupropion below these GLP-1-based therapies. The guideline emphasizes individualized decisions weighing benefits, harms, cost, and patient preferences, and is designated a 'living guideline' to be updated as evidence evolves.
