Oral insulin: a comparison with subcutaneous regular human insulin in patients with type 2 diabetes.

ABSTRACT:

Objective

To determine the pharmacokinetic and pharmacodynamic properties of an oral insulin (OI) formulation compared with subcutaneously injected regular human insulin (RHI).

Research design and methods

Ten male patients with type 2 diabetes (means +/- SD; A1C 7.0 +/- 1.1%; BMI 28.3 +/- 2.7 kg/m(2)) received either 300 units of insulin combined with 400 mg of delivery agent orally or 15 units RHI subcutaneously under isoglycemic clamp conditions.

Results

Maximum insulin concentration was greater and onset of action was faster with OI (C(max) 93 +/- 71 vs. 33 +/- 11 microU/ml; AUC(GIR)((0-1h)) 173 +/- 86 vs. 27 +/- 32 mg/kg; P < 0.05). Mean insulin concentration and glucose infusion rate returned to baseline within 3 h after OI administration. Relative bioavailabilit
