Dose-dependent subcutaneous absorption of porcine, bovine and human NPH insulins.
The absorption of 125I-labelled porcine, bovine and human neutral protamine Hagedorn (NPH) insulins was compared in 40 diabetic patients after subcutaneous injections in the thighs using doses of 6 and 24 IU (40 IU/ml). Furthermore, the absorption of porcine NPH insulin was compared with bovine NPH insulin and porcine lente type insulin in the same dose (6 IU). All these intermediately acting insulins showed similar absorption rates when administered in the same dose. However, an increase in the injected dose from 6 to 24 IU resulted in a decrease of approximately 30% in the absorption rate of all NPH insulins.
