Serum insulin concentration
Serum insulin concentration levels were detected in all subjects after they received the test or reference drugs. The two treatment groups showed basically comparable serum insulin concentration levels and trends of concentration change, as demonstrated by mean serum insulin concentration (μU/mL) versus time curves in Mean serum insulin concentration (μU/mL) versus time curves (PK analysis set). T, study drug, 300 IU, p.o.; R, reference drug, 0.1 IU/Kg, i.h.
