title: Absorption of subcutaneously administered regular human and porcine insulin in different concentrations.
abstract: The influence of the insulin concentration on its absorption from the subcutaneous tissues was studied by direct measurement of the appearance of insulin in the circulation after its subcutaneous administration. 10 units of regular insulin of semisynthetic human and porcine origin in strength of 15 units/ml, 40 units/ml, and 100/units/ml were administered as bolus to 9 healthy male volunteers, using switched-off, manually handled insulin pumps. Insulinaemia rose significantly higher (p less than 0.05) and insulin levels peaked earlier after the delivery of the 15 units/ml insulin solutions compared to the 100 units/ml insulin solutions. These findings might be of interest for type-I diabetic patients using insulin pumps that are to be loaded with regular insulin in varying concentrations.
