Semaglutide is a synthetic, long-acting analog of glucagon-like peptide-1, used to treat diabetes and obesity. Ozempic TM is a once-per-week injection formulation, while Rybelsus TM is a daily pill.

Semaglutide mildly shifted some CSF AD biomarkers, although the drug is not expected to reduce amyloid. Some scientists believe semaglutide could prevent AD or other dementias, if started earlier.
