OBJECTIVE:

The aim of the current work is to evaluate the pharmacokinetic and pharmacodynamic profile of a new human insulin preparation (jusline) following subcutaneous administration in healthy subjects, and to compare this profile with Humulin insulin.

METHODS:

20 healthy male subjects received a single dose of 0.2 U/kg of test (Jusline) or reference insulin (Humulin) during an euglycemic clamp keeping blood sugar constant (90 +/- 5 mg/dl) by changing the glucose infusion rate. Pharmacokinetic and pharmacodynamic measurements were taken from blood measurements of glucose, insulin, and C-peptide levels for tested insulin formulations.

RESULTS:

The mean values of the individual AUC ratios were well within the 90% confidence interval (100.5% for Regular, 101.9% for NPH, and 100.0% for Premixed Regular/NPH (30/70)). Similarly, Cmax and tmax were within the bioequivalence limit (80 - 125%). The maximum GIR were 10.20 mg/kg/min and 9.72 mg/kg/min for Jusline Regular and Humulin Regular, respectively. The maximum GIR were 7.09 mg/kg/min and 7.91 mg/kg/min for Jusline NPH and Humulin NPH, respectively. The maximum GIR and tGIRmax were 6.39 mg/kg/min and 6.63 mg/kg/ min for Jusline Premixed Regular/NPH (30/70) and Humulin Premixed Regular/NPH (30/70), respectively. Both insulin products produced similar suppression of endogenous C-peptide level (-29.76% to -50.22%).

CONCLUSION:

The present study demonstrated that after subcutaneous administration, there are no significant differences between Jusline and Humulin to promote peripheral glucose uptake.
