Understanding Oral Semaglutide: Mechanism andd Prefecation

Semaglutide is a synthetic analoge of thee human GLP -1 contexe, which chistates insulin secution, supresses glucagon release, slows gastric emptying, and promotes human GLP-1 context, its oral formulation was developed using a novel absorption enhanceir, sodium N- (8- adivy1- hydroksybenzoyl mex3; amino) caprylate (SNAC), which facipationates absorption expigh the gastric mucosa.

Once absorbed, semaglutide binds to GLP- 1 receptory, leading to glucose-dependent secretion andd reduced appetite. Its long half-life permits once- daily dosing.

Beyond the core PIONEER trials, extension studies (PIONEER 9 and 10) have provided data up to 104 weeks. In PIONEER 9, the HbA1c reduction with oral semaglutide 14 mg was maintained at 1.7% from baseline after 2 years, and weight loss remained at 5.1 kg. The safety profile was consistent with the class: most common adverse events were nausea (20–30%), vomiting (8–12%), and diarrhea (10–15%), which typically diminished over time. Serious adverse events, such as pancreatitis (0.3%) and diabetic retinopathy complications, occurred at rates comparable to placebo and other GLP-1 agonists.
