| 1 | Lipid-polymer hybrid nanoparticles: Development & statistical optimization of norfloxacin for topical drug delivery system显示文摘Poly lactic acid is a biodegradable, biocompatible, and non-toxic polymer, widely used in many pharmaceuticalpreparations such as controlled release formulations, parenteral preparations, surgicaltreatment applications, and tissue engineering. In this study, we prepared lipid-polymer hybrid nanoparticlesfor topical and site targeting delivery of Norfloxacin by emulsification solvent evaporationmethod (ESE). The design of experiment (DOE) was done by using software to optimize the result, andthen a surface plot was generated to compare with the practical results. The surface morphology, particlesize, zeta potential and composition of the lipid-polymer hybrid nanoparticles were characterized bySEM, TEM, AFM, and FTIR. The thermal behavior of the lipid-polymer hybrid nanoparticles was characterizedby DSC and TGA. The prepared lipid-polymer hybrid nanoparticles of Norfloxacin exhibited anaverage particle size from 178.6 ± 3.7 nm to 220.8 ± 2.3 nm, and showed very narrow distribution withpolydispersity index ranging from 0.206 ± 0.36 to 0.383 ± 0.66. The surface charge on the lipid-polymerhybrid nanoparticles were confirmed by zeta potential, showed the value from t23.4 ± 1.5 mVto t41.5 ± 3.4 mV. An Antimicrobial study was done against Staphylococcus aureus and Pseudomonasaeruginosa, and the lipid-polymer hybrid nanoparticles showed potential activity against these two.Lipid-polymer hybrid nanoparticles of Norfloxacin showed the %cumulative drug release of 89.72% in24 h. A stability study of the optimized formulation showed the suitable condition for the storage oflipid-polymer hybrid nanoparticles was at 4 ± 2 C/60 ± 5% RH. These results illustrated high potential oflipid-polymer hybrid nanoparticles Norfloxacin for usage as a topical antibiotic drug carriers. | Vivek Dave Renu Bala Yadav Kriti Kushwaha Sachdev Yadav Swapnil Sharma Udita Agrawal | 2017 | Bioactive Materials2017，2，4： | 2 |
