Polyethylene oxide chitosan

The ability of chitosan hydrochloride to enhance the transcorneal permeability of the drug has been demonstrated [289]. Polyethylene oxide (PEO) was used as a base material to which ofloxacin-containing chitosan microspheres prepared by spray-drying were added and powder compressed resulting in circular inserts (6 mm). [Pg.190]

The periodontal pocket is another site for drug delivery in the oral cavity. Needleman et al. [46] investigated three mucoadhesive polymers (cationic chitosan, anionic xanthan gum, neutral polyethylene oxide) in vitro, using organ cultures, and in vivo in patients on their periodontal and oral mucosa. Of the polymers studied, chitosan displayed the longest adhesion in vitro and on the periodontal pockets, and the shortest adhesion on oral mucosa. [Pg.179]

Graft copolymers of poloxamers and either poly(acrylic acid) or chitosan change from a sol to a gel at temperature above 37 °C. The appearing gel forms a stable matrix that can retain a drag for its sustained release. The triblock copolymer consisting of polyethylene oxide)-poly(/-lactide)-poly(ethylene oxide) (PEO-PLLA-PEO) is also temperature-sensitive but shows an opposite gellation property. At low... [Pg.384]

The easiest synthetic route is to use inert polymers (as above) doped with concentrated KOH(aq) (as above) polybenzimidazole (PBl) [57-61], poly(vinyl alcohol) (PVA) [44], composite polymers such as PVA/hydroxyapatite (PVA/HAP) [62], quatemized-PVA/alumina (QPVA/AI2O3) [63], PVA/titanium oxide (PVA/ Ti02) [64,65], chitosan and cross-linked chitosan [66-68], copolymers of epichlo-rohydrin and ethylene oxide [69], and cross-Unked PVA/sulfosuccinic acid (10 wt. % SSA) [70] have aU been doped with KOH and used as AEMs. Patent US5569559 [71] describes the use of polar polymers (most preferred being polyethylene oxide) doped with alkaline metal hydroxides (such as KOH), alkaline earth metal... [Pg.17]
