Polysaccharide-based nanocomposites and their applications.
Polysaccharide nanocomposites have become increasingly important materials over the past decade. Polysaccharides offer a green alternative to synthetic polymers in the preparation of soft nanomaterials. They have also been used in composites with hard nanomaterials, such as metal nanoparticles and carbon-based nanomaterials. This mini review describes methods for polysaccharide nanocomposite pr...
متن کاملNovel PLGA-based nanoparticles for the oral delivery of insulin
BACKGROUND Insulin is the drug therapy for patients with insulin-dependent diabetes mellitus. A number of attempts have been made in the past to overcome the problems associated with the oral delivery of insulin, but with little success. Orally administered insulin has encountered with many difficulties such as rapid degradation and poor intestinal absorption. The potential use of D-α-tocophero...
متن کاملDevelopment of acrylic-based copolymers for oral insulin delivery.
We developed nanospheres of crosslinked networks of methacrylic acid grafted with poly(ethylene glycol), and acrylic acid grafted with poly(ethylene glycol) nanospheres for use as oral insulin delivery devices. The copolymer nanospheres were synthesized via free-radical precipitation/dispersion. The average particle diameter of the copolymer gel nanospheres at various physiologically relevant p...
متن کاملHydrophobic ion pairing of an insulin-sodium deoxycholate complex for oral delivery of insulin
Insulin was complexed with sodium deoxycholate to form an insulin-sodium deoxycholate complex (Ins-SD-Comp) using an hydrophobic ion pairing method in aqueous phase to enhance the liposolubility of insulin. In order to obtain the maximal complexation efficiency, the molar ratio of sodium deoxycholate to insulin was found. The zeta potential method was used to confirm the optimal ratio for forma...
متن کاملPolysaccharide gum matrix tablets for oral controlled delivery of Cimetidine
Matrix-based tablets using 40 %w/w grewia gum were prepared by direct compression to contain cimetidine as novel drug. The formulations were compared with similar formulations using hydroxypropyl methylcelluose (Methocel), gum arabic, carboxy methylcellulose (Blanose), or ethyl cellulose (Ethocel) as polymer matrix. Also binary composite matrices containing grewia gum and the reference polymers...
