Conclusions
The present study preliminarily verified that N11005 exhibited prandial insulin characteristics in healthy Chinese male subjects. The relative bioavailability of GIR for a single dose of 300 IU oral insulin (N11005) administered in fasting condition was (1.890 ± 1.0553) % compared with subcutaneous injection of Novolin R. In general, reference and study drugs were both safe and well-tolerated.
