Abstract
Introduction: In the present study, solid lipid nanoparticles loaded with Rosiglitazone and probiotics were prepared via solvent emulsification diffusion method which is patented. As a lipid and surfactant, Gleceryl monostearate and Pluronic -68 were used in the formulation process.
Method:During characterization, it was determined that ingredient quantity variations significantly impacted Rosiglitazone loading capacity, particle size, polydispersity index, etc. In an optimized formulation of RSG-PB loaded SLNs, spherical particles with a mean particle size of 147.66 ± 1.52 nm, PDI of 0.42 ± 0.02, and loading capacity of 45.36 ± 0.20 were identified.
Result: Moreover, the developed SLNs had the potential to discharge the drug for up to 24 hours, as predicted by Higuchi's pharmacokinetic model. The SLNs were stable at 25°C/60%RH for up to 60 days. There was little to no change in particle size, PDI, or loading capacity. In addition, the number of probiotic bacteria was determined using the standard plate count procedure. Further, the antioxidant effect of the prepared formulation is evaluated using the DPPH assay method.
Conclusion: This study concludes that the method used to fabricate RSG-probiotic-loaded SLNs is straightforward and yields favorable results regarding various parameters, including sustained release property, particle size, PDI, and percent drug loading stability. Furthermore, DPPH radical scavenging activity shows the high antioxidant potential of RSG-PB SLNs when compared to RSG and probiotics alone.
Keywords: Nanoparticle, rosiglitazone, probiotics, glyceryl monostearate, pharmacokinetic, antioxidant.
