For drug delivery, characterization of liposomes regarding size, particle number concentrations, occurrence of low-sized liposome artefacts and drug encapsulation are of importance to understand their pharmacodynamic properties. In our study, we aimed to demonstrate the applicability of nano Electrospray Gas-Phase Electrophoretic Mobility Molecular Analyser (nES GEMMA) as a suitable technique f...
Ammonium sulfate is one of the subsidiary components in the stealth liposome structure. The ratio of ammonium ion bound to liposome sphere to ammonium ions outside the liposome plays an important role in drug delivery formulation; accordingly, in order to quantify the ammonium ion in the liposome structure, a rapid and sensitive method was validated using a conductivity detector. Through this m...
Erlotinib (ELT) as a small molecule with poor solubility, poor bioavailability, and instability in gastrointestinal environment, has been considered as a therapeutic agent for Non-Small-Cell Lung Cancer (NSCLC) therapy through oral administration. In the present study, ELT-liposome and ELT-NLCs were successfully prepared and characterized by assessment of the particle size, zeta potential (ZP),...
Liposome plays an important role in medical and pharmaceutical science as e.g. nano scale drug carriers. Liposomes are vesicles of varying size consisting of a spherical lipid bilayer and an aqueous inner compartment. Magnet-driven liposome used for the targeted delivery of drugs to organs and tissues. These liposome preparations contain encapsulated drug components and finely dispersed magneti...
the use of liposome as an adjuvant and a vaccine carrier has been cited previously in the literature. it has also been shown to be effective in enhancing the immunogenicity of vaccine candidates. balb/c mice immunized subcutaneously with outer membrane protein (omp) of brucella abortus s19 vaccine strain entrapped in a commercial cationic liposome (s19-omp-liposome) for vaccine delivery, showed...
Abstract Background Cosmeceuticals are cosmetic products with biologically active components that have drug-like benefits. currently rapidly growing segments encompassing the personal care industry and numerous topical cosmetics-based therapies for treating different skin conditions. The barrier nature of causes limitations to treatment. effectiveness this cosmeceutical product has been enhance...
PURPOSE Celecoxib is nonsteroiddal anti-inflammatory drug that has been used extensively to treat patients with arthritis. The aim of the present study was to formulate and characterize liposomal vesicles loaded with celecoxib. METHODS Liposomes were prepared by thin film method using soya lecithin and cholesterol. The release of drug was determined using a dialysis membrane method. Liposomes...
