Exploring the hypoglycemic potential of HuGLP-1-loaded bilosomes in controlling type 2 diabetes mellitus.

Background: Type 2 diabetes mellitus (T2DM) is the most devastating disease and it necessitates therapeutic intervention for its effective management. Human Glucagon-like peptide-1 (HuGLP-1) is the potential candidate in the treatment of T2DM; however, it limits its utilization owing to its solubility and stability issues.

Aims: The current investigation aims to develop HuGLP-1-loaded bilosomes as a novel strategy for managing T2DM.

Materials And Methods: The HuGLP-1-loaded bilosomes were developed and characterized for its size, polydispersity index, surface charge, entrapment efficiency, morphology, drug release, and stability studies. The hypoglycemic potential and histopathology were studied using streptozotocin-induced diabetic rats.

Results: Bilosomes were successfully developed with size of 197.96 ± 0.61 nm, polydispersity index 0.191 ± 0.01 and surface charge of -27.63 ± 1.02 mV. The in vitro release of HuGLP-1-loaded bilosomes showed sustained release profile of HuGLP-1 extending over 24-h period, in compared to plain HuGLP-1 solution, and follows Weibull release kinetics model. The HuGLP-1-loaded bilosomes revealed significant hypoglycemic effects in comparison to both oral and subcutaneous HuGLP-1 solutions. Histopathological evaluations revealed that HuGLP-1-loaded bilosomes showed promising improvement in histology of liver, kidney, and intestines.

Conclusion: The HuGLP-1-loaded bilosomes were found to be potential therapeutic approach for the effective management of T2DM.
