Introduction: Nanofiber-based ocular inserts are considered smart candidates for delivering various drugs and biopharmaceuticals to different layers of the eye, and they have good bioavailability compared to conventional ocular formulations such as eye drops.
Aim: The current study aimed at developing stable, preservative-free electrospun nanofiber-based ocular inserts of amphotericin B (AmphB) as a promising candidate for treating sight-threatening fungal keratitis.
Methods: The AmphB solubility was studied using cyclodextrin (γ-CD). The precursor solutions for electrospinning contain γ-CD to improve AmphB solubility, polyvinyl alcohol (PVA)as fibers forming polymer, and sodium taurocholate (STC) as permeation and solubility enhancer. By varying the amount of γ-CD, PVA, and STC, nine different formulations of AmphB-loaded fibers were prepared by electrospinning technique. The resulting samples were evaluated in terms of morphology, physicochemical characteristics, in vitro drug release, and cytocompatibility.
Results: The AmphB solubility was successfully increased using with γ-CD. From the phase solubility profile, it was observed that the solubility of AmpB was increased linearly as a function of γ-CD concentration to a specific limit (10% w/w of γ-CD). The solution was stable under heating for 2 hours at 60 °C. All samples were found to be fibrous, and increasing cyclodextrin concentration improved the fiber's morphology. FTIR suggested the formation of amorphous solid dispersion, which was confirmed by XRD. All formulations showed fast AmphB release and homogenous drug distribution.
Conclusion: The developed stable nanofibrous webs can be considered a promising candidate for AmphB ocular delivery and overcoming the ocular challenging barriers faced by conventional ocular formulations.
