Solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) are colloidal carrier systems providing controlled release profiles for many substances. Clotrimazole-loaded SLN and NLC were prepared by the hot high pressure homogenization technique in order to evaluate the physical stability of these particles, as well as the entrapment efficiency of this lipophilic drug and its in vitr...

Immune suppression resulting from chemoprophylaxis and potential drug interaction were investigated in experimental animals pre-medicated with ampicillin and chloroquine followed by immunization with bovine serum albumin bearing liposomes prepared by the reverse phase evaporation method. The prepared liposomes were evaluated for particle size, entrapment efficiency and in vitro release. Humoral...

Fenofibrate lipospheres were prepared by the melt dispersion technique. Critical parameters influencing particle size and entrapment efficiency were optimized by applying the L9 Taguchi experimental design. Entrapment efficiency of up to 87 % was obtained for the optimized formulation on increasing olive oil up to 30 % in the lipid carrier. Particle size analysis by microscopy and SEM revealed ...

Chitosan (CS) nanoparticles have been developed as a versatile drug delivery system to transport drugs, genes, proteins, and peptides into target sites. Demands on fluorescent nanoparticles have increased recently due to various applications in medical and stem-cell-based researches. In this study, fluorescent CS nanoparticles were prepared by a mild method, namely, complex coacervation. Entrap...

Present study was undertaken to assess the potential of Glycerosomes as a novel drug delivery system for topical application of Minoxidil. Pre-formulation studies were done for identification of drug as well as for determination of its physiochemical properties. Spectra of various mixtures of drug and excipients do not show any additional peak thus, indicating compatibility with each other. Gly...

Today, cancer remains one of the major diseases that lead to death. The main obstacle in chemotherapy as a main cancer treatment is the toxicity to normal cells due to Multidrug Resistance (MDR) after the use of anticancer drugs. Proposed solution to overcome this problem is the use of MDR efflux inhibitor of cinchona alkaloids which is delivered together with anticancer drugs encapsulated in t...

Zidovudine-ethylcellulose microspheres were prepared by water-in-oil-in-oil double emulsion solvent diffusion method. Spherical free flowing microspheres having an entrapment efficiency of 32-54% were obtained. The effect of polymer-drug ratio, surfactant concentration for secondary emulsification process, volume of processing medium and stirring speed of secondary emulsification process was ev...

This paper describes the conditions of preparation of poly(o-caprolactone) (PCL) microparticles with a mean size between 5 and 10 mm, obtained by a double emulsion-solvent evaporation technique, suitable for oral vaccine delivery. Bovine serum albumin (BSA) was used as water-soluble model antigen for encapsulation. Different parameters influencing the microparticle size, the BSA loading and ent...

Background and purpose: This study investigated the effect of different HLBs on these nanoparticles using spironolactone solid lipid nanoparticles. Materials and methods: The spironolactone loaded SLN was prepared by emulsion/solvent evaporation technique followed by ultrasonication. In this study, Palmitic acid was used as carrier. Different weight ratio of drug, carrier, Span60 and Tween80 w...

Amphotericin B (AmB)/poly(lactic acid)-b-poly(ethylene glycol) (PLA-b-PEG) nanoparticles coated with polysorbate 80 (Tween-80) were prepared by nanoprecipitation for transport across the blood-brain barrier (BBB). The effects of Tween-80 on the size and distribution, entrapment efficiency and release behavior of AmB/PLA-b-PEG nanoparticles were investigated. Furthermore, the brain targeting and...
