Formulation, Optimization, and Evaluation of Allopurinol-Loaded Bovine Serum Albumin Nanoparticles for Targeting Kidney in Management of Hyperuricemic Nephrolithiasis : Formulation, optimization, and evaluation of ABNPs for kidney targeting. AAPS PharmSciTech. 2020 Jun 02;21(5):164 Authors: Kandav G, Bhatt DC, Jindal DK, Singh SK Abstract The aim of present research work was to design, fabricate, optimize, and evaluate allopurinol (ALLO)-loaded bovine serum albumin nanoparticles (ABNPs) for kidney targeting of the drug and exploring the potential of fabricated ABNPs for management of hyperuricemia-related nephrolithiasis. ABNP formulation was prepared by employing desolvation technique, and its optimization was conducted by 2-factor-3-level central composite design (CCD) in order to achieve minimum particle size (PSA) and polydispersity index (PDI), maximum entrapment efficiency (EE), and zeta potential (ZP). Further, the optimized formulation (ABNPsopt) was also assessed for in vitro drug release study, TEM, DSC, XRD analysis, FTIR spectroscopy, and in vivo animal study. The in vivo study revealed that after 2 h of ABNPsopt administration, a significant concentration of ALLO was present in kidney (21.26-fold) as compared with serum while in case of standard pure drug group; no drug was seen in mice kidney and serum post 2 h administration, which indicates successful targeting of ALLO by formulating its albumin nanoparticles.
