 Solid lipid nanoparticles (SLNs) of piroxicam where produced by solvent emulsification diffusion method in a solvent saturated system. The SLNs where composed of tripamitin lipid, polyvinyl alcohol (PVAL) stabilizer, and solvent ethyl acetate. All the formulation were subjected to particle size analysis, zeta potential, drug entrapment efficiency, percent drug loading determination and in-vitro release studies. The SLNs formed were nano-size range with maximum entrapment efficiency. Formulation with 435nm in particle size and 85% drug entrapment was subjected to scanning electron microscopy (SEM) and transmission electron microscopy (TEM) for surface morphology, differential scanning calorimetry (DSC) for thermal analysis and short term stability studies. SEM and TEM confirm that the SLNs are nanometric size and circular in shape. The drug release behavior from SLNs suspension exhibited biphasic pattern with an initial burst and prolong release over 24 h.

Purposes: Cystic echinococcosis (CE) is a serious contemporary public health problem. Different CE treatment methods are of considerable importance, with albendazole (ABZ) being one of the most preferred drugs for CE treatment and prophylaxis. In this study, we evaluated the nephrotoxicity caused by ABZ and ABZ-loaded solid lipid nanoparticles (SLNs) in mice with experimental hydatid cyst. Methods: ABZ-loaded SLNs were produced by micro-emulsification and a high shear homogenization technique. Thereafter, we evaluated the physicochemical characterization of the product. Live protoscolices were injected into mice to induce experimental hydatidosis. Mice were then treated with ABZ and ABZ-loaded SLNs. The nephrotoxicity effects were evaluated by biochemical and histopathological surveys. Results: Significantly different blood urea nitrogen (BUN) levels were observed between the two infected groups (ABZ treatment and ABZ-loaded SLN treatment) and the control group. The kidney malondialdehyde (MDA) and glutathione (GSH) levels of the infected groups were not significantly different from those of the control group. The histopathological study revealed nephropathic and pathologic changes in the ABZ and ABZ-loaded SLN groups. Conclusion: ABZ formulated for ABZ-loaded SLNs had a more prominent chemoprophylactic efficacy on CE and fewer side effects than ABZ alone. Neither ABZ nor ABZ-loaded SLNs caused significant biochemical and histopathological defects on the kidney, and all functional biochemical markers stayed within the normal range. Therefore, ABZ-loaded SLNs could be a potential new product for CE treatment.
