Patent Summary

Improving oral delivery of GLP-1 peptides like glucagon-like peptide-1 (GLP-1) for treating diabetes and obesity. The invention involves designing granules for tablet formulations containing GLP-1 peptides and delivery agents like SNAC. The granules are prepared by mixing the peptide, fillers, and binders, then the delivery agent mix. This two-step granulation process allows separate optimization of peptide and delivery properties. The resulting granules have improved dissolution profiles for faster GLP-1 release compared to co-granulating.
