Controlled Release of Tazarotene from Magnetically Responsive Nanofiber Patch: Towards More Efficient Topical Therapy of Psoriasis

Abstract

Electrospun polycaprolactone nanofibers with embedded magnetic nanoparticles were developed for use in the topical delivery of antipsoriatic drugs. To test a hydrophobic drug, a tazarotene has been used, which is an efficient retinoid derivative. Such a smart hyperthermia nanofiber system with self-generated heat from the incorporated magnetic nanoparticles induced drug release in response to on–off switching of alternating magnetic fields for the delivery of tazarotene through the skin, as quantified using Franz cells. This highly efficient external field-controllable system with minimal skin irritation could create a new avenue for the topical therapy of psoriasis.
