An oral formulation of the glucagon-like peptide-1 (GLP-1) receptor agonist semaglutide (Rybelsus – Novo Nordisk) has been approved by the FDA for once-daily treatment of type 2 diabetes in adults. Semaglutide, which has been available in a subcutaneously-injected formulation (Ozempic)1 since 2017, is the first GLP-1 receptor agonist to become available for oral administration; the 4 other GLP-1 receptor agonists currently available in the US are administered by subcutaneous (SC) injection.
