Longer Fasting After Rybelsus Administration Contributes Higher Efficacy

Recent pharmacological topic for diabetes includes clinical application of Glucagon-like peptide 1 receptor agonists (GLP-1 RAs). Among them, oral semaglutide (Rybelsus) has been developed as the first oral form of GLP-1RA by useful application of sodium N-(8-[2-hydroxybenzoyl] amino) caprylate (SNAC). Semaglutide concentration in the blood was compared when fasting time period after Rybelsus administration would be 15, 30, 60 and 120 minutes. As a result, the concentration ratio after 4 hours was 1.00, 1.67, 2.60 and 3.06, respectively. Authors have experienced a diabetic case of remarkable efficacy as HbA1c -1.4% and weight -5kg, who kept 3-4 hours fasting after Rybelsus intake.
