Study Summary
In patients with type 2 diabetes:
Bedtime dosing with oral insulin suppresses overnight-fasting insulin secretion
Bedtime dosing with oral insulin may improve fasting hepatic insulin sensitivity, evidenced by unchanged fasting glycemia with reduced fasting insulinemia
The physiologic actions of oral insulin are exerted far longer (ɴ hrs) than predicted by its rapid systemic pharmacokinetics (Cmax @ 25 min)
Whether long-term treatment with oral insulin may preserve ß-cell function warrants further study
