Abstract

A drug-loaded electrospun mat is a potential fibrous material for cancer treatment after a surgery procedure. In this study, the methacrylic copolymer poly(methyl methacrylate-co-methacrylic acid) [P(MMA-co-MAA)] was synthesized by semi-continuous heterophase polymerization as a nanofiber carrier to load an anticancer drug, doxorubicin hydrochloride (DOX). Eudragit® S100 (ES100) nanofibers loaded with DOX were also prepared for comparison. The electrospun nanofibers were loaded at different DOX concentrations, where the homogeneous fiber morphology did not change with the drug-loaded increase. The confocal microscopic images indicated that the drug was incorporated to a major extent into the synthesized copolymer than the ES100 nanofibers, through electrostatic interactions or hydrogen bonding. The In-vitro release profiles of DOX presented a lower release rate for the synthesized copolymer around 12% after 72 h, compared to 44% released from ES100 copolymer. Both copolymers presented a two-stage diffusion-controlled mechanism, which obeyed Fick's second law. Based on these results, the synthesized methacrylic copolymer exhibited a high potential to release the drug in a sustained and prolonged manner. Thus, P(MMA-co-MAA) DOX-loaded electrospun mats have the potential to be used as local implantable fibrous material for postsurgical cancer treatment.
