Formulation and Physicochemical Characterization of Lycopene-Loaded Solid Lipid Nanoparticles.
PURPOSE Lycopene belongs to the carotenoids that shows good pharmacological properties including antioxidant, anti-inflammatory and anticancer. However, as a result of very low aqueous solubility, it has a limited systemic absorption, following oral administration. METHODS Here, we prepared a stable lycopene-loaded solid lipid nanoparticles using Precirol® ATO5, Compritol 888 ATO and myristic...
متن کاملFormulation of diblock polymeric nanoparticles through nanoprecipitation technique.
Nanotechnology is a relatively new branch of science that involves harnessing the unique properties of particles that are nanometers in scale (nanoparticles). Nanoparticles can be engineered in a precise fashion where their size, composition and surface chemistry can be carefully controlled. This enables unprecedented freedom to modify some of the fundamental properties of their cargo, such as ...
متن کاملTwo-step nanoprecipitation for the production of protein-loaded PLGA nanospheres
One of the first methods to encapsulate drugs within polymer nanospheres was developed by Fessi and coworkers in 1989 and consisted of one-step nanoprecipitation based on solvent displacement. However, proteins are poorly encapsulated within polymer nanoparticles using this method because of their limited solubility in organic solvents. To overcome this limitation, we developed a two-step nanop...
متن کاملFormulation and Evaluation of Octreotide Acetate Loaded Plga Microspheres
Objective: The objective of the present work was to formulate and evaluate controlled release Octreotide acetate microspheres for subcutaneous administration for treating symptoms associated with metastatic carcinoid and vasoactive intestinal peptide tumors (VIPsecreting tumors) and acromegaly effectively and also to improve patient compliance with fewer side effects. Octreotide is a long actin...
متن کاملFormulation and Characterization of Antigen-loaded PLGA Nanoparticles for Efficient Cross-priming of the Antigen
BACKGROUND Nanoparticles (NPs) prepared from biodegradable polymers, such as poly (D,L-lactic acid-co-glycolic acid) (PLGA), have been studied as vehicles for the delivery of antigens to phagocytes. This paper describes the preparation of antigen-loaded PLGA-NPs for efficient cross-priming. METHODS NPs containing a similar amount of ovalbumin (OVA) but different sizes were produced using a mi...
