Coadministration of Polypeptide-k and Curcumin Through Solid Self-Nanoemulsifying Drug Delivery System for Better Therapeutic Effect Against Diabetes Mellitus: Formulation, Optimization, Biopharmaceutical Characterization, and Pharmacodynamic Assessment

An attempt has been made to prepare solid self-nanoemulsifying drug delivery system (SNEDDS) of polypeptide-k (PPK) and curcumin (CRM) using Labrafil M1944 CS as oil, Tween-80 as surfactant, Transcutol P as cosurfactant and Aerosil-200 (A-200) as porous hydrophobic carrier for improving their antidiabetic potential through oral delivery. Box–Behnken Design was used to optimize the liquid formulation based on the results of the mean droplet size,...
