Nanostructured Lipid Carrier-Based Delivery of Pioglitazone for Treatment of Type 2 Diabetes

Pioglitazone (PGZ) is utilized as a therapeutic agent in the management of (type 2) diabetes to control blood glucose levels. The existing research work was intended to make and optimize PGZ-containing NLCs (nanostructured lipid carriers). The fabricated nanostructured lipid carrier preparation was optimized by using different concentrations of the surfactants (Tween 80 and Span 80) and solid lipid (Compritol® 888 ATO) and liquid lipid (Labrasol®) while keeping the concentration of drug (PGZ), and co-surfactants (poloxamer 188) the same. The optimized NLC formulation (PGZ-NLCs) was further assessed for physical and chemical characterization, in vitro PGZ release, and stability studies. The optimized PGZ-NLCs have shown an average diameter of 150.4 nm, EE of 92.53%, PDI value of 0.076, and zeta-potential of −29.1 mV, correspondingly. The DSC thermal analysis and XRD diffractograms had not presented the spectrum of PGZ, confirming the comprehensive encapsulation of PGZ in the lipid core. PGZ-NLCs showed significantly extended release (51% in 24 h) compared to the unformulated PGZ. Our study findings confirmed that PGZ-NLCs can be a promising drug delivery system for the treatment of type 2 diabetes.
