Brief Summary

A study of the bioavailability of insulin after infusion in the duodenum in healthy volunteers.

Detailed Description

METHODOLOGY All subjects will be admitted fasting to the Clinical Trial Unit at Århus Community Hospital at 8 a.m. A Gastrointestinal tube will be placed in Duodenum distal to papilla Vaterii with a pH of approximately 7.0 as measured by the pH meter distal in the tube. An indwelling catheter for glucose infusion (20 %) in cases of hypoglycaemia will be placed in an antecubital vein. In the contralateral anticubital vein a catheter will be placed for blood sampling. All subjects will have 4 tests with duodenal infusion of the insulin Aspart solution. The first 4 volunteers will receive 4 doses of insulin Aspart solution in 1 ml (150, 300, 600 and 1000 IU) with 3-6 hours apart. Blood sampling for Insulin Aspart, total insulin, and glucose (Beckmann apparatus) will be done every 10 minutes the first two hours, and then every 20 minutes. When final the subjects will receive a meal before leaving the hospital.

Based on data from the pilot a dose will be determined for the remaining 8 subjects. These will then based again on results from the pilot on two separate study days receive 4 infusions with 3-6 hours split. Two infusions will be at pH 7 and two infusions will be more proximal at a pH of 5.5 (two different insulin concentrations but the same dose given at the two places in Duodenum). Frequency and interval of blood sampling in the second part will be determined by results from the pilot study. For comparison with the clinical situation and estimation of bioavailability all subjects will receive a subcutaneous and an intravenous (iv) bolus injection of 6 IU of insulin Aspart. The iv injection will be followed by blood sampling for three hours as above, but every 5 minutes the first two hours, and the sc injection will be followed by blood sampling for three hours as above, but again with 10 minutes interval the first two hours.
