1. The absorption of 6U of soluble human insulin following subcutaneous injection into the anterior abdominal wall, thigh and into the thigh following admixture with aprotinin was assessed in normal subjects. The plasma immunoreactive insulin profiles were determined during a 6 h post injection period in subjects receiving concomitantly somatostatin to suppress endogenous insulin secretion. 2. Subcutaneous injection of human insulin into the anterior abdominal wall compared with the thigh led to significantly higher incremental insulin levels between 30 and 50 min (P less than 0.05) followed by lower values at 240‐300 min (P less than 0.05). The absorption of soluble human insulin from a subcutaneous depot is faster from the anterior abdominal wall compared with the thigh associated with a faster clearance from plasma. 3. Injection into the thigh of insulin admixed with aprotinin resulted in higher plasma insulin levels at 10 min (P less than 0.001) and 20 min (P less than 0.05) compared with insulin given alone. Similarly, the insulin level was significantly higher with the admixture between 10 and 20 min (P less than 0.05) compared with insulin into the anterior abdominal wall. 4. Admixture of insulin with aprotinin therefore leads to an acceleration of the early phase of absorption from subcutaneous tissue due to a local hyperaemic effect.
