AB  - The incorporation of polymers into drug delivery vehicles has been shown to be a useful approach to prolong the
residence time of drugs in the precorneal tear film and to improve penetration into biological membranes. The
main objective of this research was to formulate novel viscous eye drops with ketotifen as the active ingredient,
containing the polysaccharides: chitosan (MCH), hydroxypropyl guar gum (HPG) and hyaluronic acid (SH) alone
and in combination as functional polymers. DSC and FT-IR techniques showed the compatibility between
ketotifen and polymers. Physicochemical and rheological analysis at ambient and simulated physiological conditions, as well as the evaluation of mucoadhesive properties showed that vehicles containing combinations of
polymers have suitable physicochemical and functional properties with demonstrated synergism between
combined polymers (MCH and HPG i.e. SH and HPG). The drug permeability was successfully estimated in vitro
using HCE-T cell-based models. MTT cytotoxicity assay demonstrates that the tested formulations were non-toxic
and well tolerated. In vivo preclinical study on mice revealed that both vehicles containing mixed polymers
enhanced and prolonged the antipruritic/analgesic-like effect of ophthalmic ketotifen. Based on these results,
both combinations of polysaccharide polymers, especially SH-HPG, could be considered as potential new carriers
for ketotifen for ophthalmic use.
