Experimental: Oral Insulin
oral insulin capsule formulation
Drug: Oral insulin
oral insulin capsule formulation (150 U insulin/200 mg 4-CNAB in one capsule); single dose administration of 300 U insulin (in two capsules) and of 150 U insulin (one capsule) on two separate dosing days.
Active Comparator: Subcutaneous Insulin
Subcutaneous injection of regular human insulin
Drug: regular human insulin
subcutaneous injection of 15 U regular human insulin; single dose administration on one separate dosing visit.
Other Name: Humulin R (100 U/mL)
This study was a single centre, randomized, 3-period crossover study performed in patients with type 2 diabetes. Patients received single doses of an oral insulin formulation and subcutaneous regular human insulin on separate visits.
The primary objective of this study was to compare the pharmacokinetic and pharmacodynamic properties of an oral insulin formulation with that of 15 U subcutaneous injected regular human insulin.
Pharmacokinetic and pharmacodynamic parameters including bioavailability and bioefficacy were measured during 6-hour glucose clamp experiments.
Study duration: 2 months
