In people with obesity and prediabetes, the drug liraglutide lowers blood glucose levels after fasting and after meals within two weeks, even without weight loss. This effect is not seen with other...
Mechanism
Synthesis from 1 study
Liraglutide works faster and better than diet or other drugs because it strongly and directly turns on a specific signal in the liver, muscle, and pancreas that tells the body to stop making too much sugar and start using it better. Other ways to boost the body’s own version of this signal don’t...
Most probable mechanism
Liraglutide binds to special receptors on the liver and muscle cells, telling them to take up more sugar from the blood and stop making so much sugar. It also tells the pancreas to release less of a hormone that tells the liver to make sugar. This happens quickly, even before any weight loss, and doesn't happen when the body just makes more of its own version of the signal.
Liraglutide binds to GLP-1 receptors on pancreatic alpha cells, directly inhibiting glucagon secretion
Reduced glucagon levels decrease hepatic glucose production through suppressed gluconeogenesis and glycogenolysis
Liraglutide activates GLP-1 receptors on hepatocytes and skeletal muscle cells, enhancing glucose uptake and reducing insulin resistance
Improved glucose homeostasis reduces the demand for insulin secretion, leading to lower insulin and C-peptide levels without beta-cell dysfunction
