Bioadhesive properties of Gantrez nanoparticles.
Bioadhesive nanoparticles have been proposed as carriers for the oral delivery of poorly available drugs and facilitate the use of this route. This work summarises some experiments describing the bioadhesive potential of Gantrez nanoparticles fluorescently labeled with rhodamine B isothiocyanate. The adhesive potential of Gantrez was found to be stronger when folded as nanoparticles than in the...
متن کاملImproved i.p. drug delivery with bioadhesive nanoparticles.
The i.p. administration of chemotherapy in ovarian and uterine serous carcinoma patients by biodegradable nanoparticles may represent a highly effective way to suppress peritoneal carcinomatosis. However, the efficacy of nanoparticles loaded with chemotherapeutic agents is currently hampered by their fast clearance by lymphatic drainage. Here, we show that a unique formulation of bioadhesive na...
متن کاملCyclodextrin-gantrez Nanoparticles as Bioadhesive Carriers for Oral Drug Delivery
Introduction Oral delivery is the most convenient and desired way for drug delivery. The major factor determinant for bioavailability of orally administered drug is the membrane permeability and drug solubility in the intestinal lumen. Many drugs show bioavailability problems due to their low water solubility, slow dissolution rate and instability in the gastrointestinal tract. One possibility ...

متن کاملNatural bioadhesive biodegradable nanoparticles-based topical ophthalmic formulations for sustained celecoxib release: In vitro Study
Background: Our goal was to prepare and evaluate topical ophthalmic formulations containing optimized celecoxib-loaded bioadhesive cationic chitosan or anionic alginate nanoparticles for sustained release of celecoxib. Methods: Nanoparticles were prepared using a spontaneous emulsification solvent diffusion method. Different concentrations of polymers, emulsifier and stabilizers were used to op...
