Summary Subcutaneous insulin absorption kinetics were assessed in 50 healthy study subjects (21 female, 29 male; age 26±3 years, BMI 22.5±1.8 kg/m2; mean±SD) during 45 min after periumbilical injection of soluble human U40- or U100-insulin (0.15 IU/kg). Subcutaneous fat thickness was measured by ultrasound, and skin temperature at the injection site was registered. Serum insulin concentrations increased within 30 min from basal values of 37±15 to 140±46 pmol/l after U40-insulin and from 36±10 to 116±37 pmol/l after U100-insulin (p〈0.001). After 45 min serum insulin concentrations were 164±43 pmol/l with U40-insulin and 128±35 pmol/l with U100-insulin (p〈0.001). Decline in blood glucose levels and suppression of C-peptide were comparable. The serum insulin levels reached 30 and 45 min after U40- and U100-insulin injection were positively correlated with skin temperature (p〈0.0008), and negatively correlated with subcutaneous fat thickness (p〈0.009). In conclusion, the lower insulin concentration of U40-insulin, higher skin temperature, and a thinner subcutaneous fat tissue at the injection site are associated with accelerated and enhanced subcutaneous insulin absorption.
