Production of Electrospun Fast-Dissolving Drug Delivery Systems with Therapeutic Eutectic Systems Encapsulated in Gelatin

Fast-dissolving delivery systems (FDDS) have received increasing attention in
the last years. Oral drug delivery is still the preferred route for the administration of
pharmaceutical ingredients. Nevertheless, some patients, e.g. children or elderly people, have
difficulties in swallowing solid tablets. In this work, gelatin membranes were produced by
electrospinning, containing an encapsulated therapeutic deep-eutectic solvent (THEDES)
composed by choline chloride/mandelic acid, in a 1:2 molar ratio. A gelatin solution (30% w/
v) with 2% (v/v) of THEDES was used to produce electrospun fibers and the experimental
parameters were optimized. Due to the high surface area of polymer fibers, this type of
construct has wide applicability. With no cytotoxicity effect, and showing a fast-dissolving
release profile in PBS, the gelatin fibers with encapsulated THEDES seem to have promising
applications in the development of new drug delivery systems.
