What is Saxenda?
Saxenda is the brand name for a prescription-only, injectable medication known as Liraglutide. It is a medication approved for weight management as an adjunct to diet and exercise. Liraglutide belongs to a group of medications known as glucagon-like peptide-1 receptor agonist (GLP-1 receptor agonist), also known as incretin mimetics. Saxenda is very similar to a GLP-1, a hormone that occurs naturally in the body which is released in response to food intake and acts as a physiological regulator of appetite and digestion.
GLP-1 that is produced by our body is rapidly broken down, resulting in a short half life of less than 2 minutes. Saxenda mimics GLP-1, but is much longer lasting, with a half life of about 13 hours when injected. Because of its long half life, it can act on the GLP-1 receptor for longer, exerting its physiological effects.
GLP-1 receptors can be found in several organs, including the brain, pancreas, gastrointestinal tract, heart, vasculature and kidneys. Saxenda works by binding to the receptors in the arcuate nucleus of the hypothalamus in the brain, where it stimulates satiety and inhibits hunger neurons. Because of this, you eat less, leading to weight loss.
What is the use of Saxenda?
If you are obese, or overweight with weight-related medical problems (such as high blood pressure, high cholesterol, or type 2 diabetes), this medication can help with weight loss, and keeping the weight off. Saxenda is meant to be used alongside diet control and exercise.
A study published in 2017 was conducted with 3731 patients followed up over 56 weeks. The patients either had a BMI of 30 or more without diabetes, or a BMI of 27 or more with at least one weight related-medical problem. These patients were split into two groups. Both groups were told to control their diet and exercise.
One group was given Saxenda and the other group was given a placebo. 1 of 3 patients treated with Saxenda achieved weight loss of more than 10%. Patients treated with Saxenda who completed the trial achieved a mean weight loss of 9.2% and kept the weight off for the one year follow up. Patients also experienced multiple improvements in cardiometabolic risk factors.
