WebAfter subcutaneous administration in rats, the mean residence time (MRT) of INP-loaded 30% PF-127 was delayed from 1.3±0.3 h to 3.8±0.5 h and the AUC was 1.5 times higher than that of INP. 33 The high serum insulin level lasted for 12 hours. However, the studied system did not meet the expected sustained release behavior.
