FDA Approved
GLP-1 Agonist
Overview

A once-daily GLP-1 receptor agonist FDA-approved for type 2 diabetes. Shorter-acting than semaglutide, with a stronger effect on postprandial glucose. Also available in a fixed-ratio combination with insulin glargine (Soliqua).

A GLP-1 receptor agonist originally developed for type 2 diabetes, now widely prescribed for weight management. One of the most commercially successful peptide drugs in history.

Mechanism of Action

Activates GLP-1 receptors, stimulating glucose-dependent insulin secretion and suppressing glucagon. Its shorter duration of action produces a more pronounced effect on gastric emptying and postprandial glucose compared to longer-acting GLP-1 agonists.

Mimics the incretin hormone GLP-1, stimulating insulin secretion, suppressing glucagon release, slowing gastric emptying, and reducing appetite through central nervous system signaling. The result is improved blood sugar control and significant weight loss.

Common Uses
  • Type 2 diabetes (adjunct to diet and exercise)
  • Postprandial glucose control
  • Combined with basal insulin (Soliqua)
  • Weight management
  • Type 2 diabetes treatment
  • Blood sugar regulation
  • Cardiovascular risk reduction
Known Risks
  • Nausea and vomiting (common, usually transient)
  • Diarrhea
  • Headache
  • Hypoglycemia when combined with sulfonylureas
  • Pancreatitis (rare)
  • Nausea and vomiting (common, usually transient)
  • Pancreatitis (rare but serious)
  • Gallbladder issues
  • Potential thyroid tumor risk (animal studies)
  • Muscle mass loss alongside fat loss
  • GI side effects (diarrhea, constipation)
Regulatory Status
FDA Approved

FDA-approved as Adlyxin (2016) for type 2 diabetes. Also available as Soliqua 100/33 (fixed-ratio combination with insulin glargine). Less weight loss than semaglutide but better postprandial control.

FDA Approved

FDA-approved as Ozempic (diabetes, 2017), Wegovy (weight management, 2021), and Rybelsus (oral, diabetes, 2019). Multiple dosage forms and indications approved.
