The present study thus aimed at the development and physicochemical characterization of solid lipid nanoparticles loaded with crude extract Piper corcovadensisroots (SLN-CEPc) chitosan-coated withcrude P. (C-SLN-CEPc), as well determination its antimycobacterial activity against Mycobacterium tuberculosisH37Rv, cytotoxicity Vero cell line evaluation in hemolysis assay. Both formulations contain...

Preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of Nile red-loaded solid lipid nanoparticles. Nanoparticles (NPs) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. To solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...

Objective: This work compares the occlusive effect and the penetration enhancement ability of solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC), through in vitro skin. Methods: SLN and NLC were prepared by high shear homogenization and characterized by size, polydispersity index, zeta potential, morphology and physical stability. Occlusive effect was assessed by an in vitr...

The aim of this work was to produce and characterize cetyl palmitate-based solid lipid nanoparticles (SLN) containing insulin, and to evaluate the potential of these colloidal carriers for oral administration. SLN were prepared by a modified solvent emulsification-evaporation method based on a w/o/w double emulsion. The particle size, zeta potential and association efficiency of unloaded and in...

Catalase-loaded solid lipid nanoparticles (SLNs) were prepared by the double emulsion method (w/o/w) and solvent evaporation techniques, using acetone/methylene chloride (1:1) as an organic solvent, lecithin and triglyceride as oil phase and Poloxmer 188 as a surfactant. The optimized SLN was prepared by lecithin: triglyceride ratio (5%), 20-second + 30-second sonication, and 2% Poloxmer 188. T...

Solid Lipid Nanoparticles (SLN) have been prepared by high-pressure homogenization and optimized in order to protect ferulic acid from Ferula assa-foetida L. extract. The influence of lipid surfactant concentration on the mean particle size (Z-Ave), polydispersity index (PDI), zeta potential (ZP) SLN was analyzed. In addition, other parameters for preparation acid-loaded nanoparticles, such as ...

Sorafenib solid lipid nanoparticles (S-SLN) were prepared by emulsion evaporation-solidification at low temperature. Morphology was examined by transmission electron microscope. Particle size and zeta potential were determined by laser granularity equipment. Encapsulation efficiency (EE) was detected by Sephadex gel chromatography and high-performance liquid chromatography (HPLC). The in vitro ...

Hydatid disease caused by tapeworm is an increasing public health and socioeconomic concern. In order to enhance the therapeutic efficacy of praziquantel (PZQ) against tapeworm, PZQ-loaded hydrogenated castor oil solid lipid nanoparticle (PZQ-HCO-SLN) suspension was prepared by a hot homogenization and ultrasonication method. The stability of the suspension at 4°C and room temperature was evalu...

Solid lipid nanoparticles of atovaquone (ATQ-SLN) were prepared by high shearhomogenization method using tripalmitin, trilaurin, and Compritol 888 ATO as the lipidmatrices and Phospholipon 90H, Tween 80, and poloxamer 188 as the surfactants. Optimizationof the formulations was conducted using 6 sets of 24 full-factorial design based on fourindependent variables that were the number of homogeniz...
