Herein, two polymer-based nanofibrous systems were developed using poly-lactic-co-glycolic-acid (PLGA) and polyvinylpyrrolidone (PVP) loaded with a combination of an antibiotic (Fusidic acid, FA) and a local anesthetic (Lidocaine, LDC) via electrospinning technique for an expedited healing process by preventing bacterial infections while reducing the pain sensation.Results: The fabricated nanofibers showed an excellent morphology with an average fiber diameter of 556 ± 71 nm and 291 ± 87 nm for the dual drug-loaded PLGA/PVP and PVP nanofibers, respectively. The encapsulation efficiency (EE%) and drug loading (DL) studies revealed that PLGA/PVP loaded with FA and LDC exhibited EE% of 92% and 75%, respectively, while the DL was measured at 40 ± 8 μg/mg for FA and 32 ± 7 μg/mg for LDC. Furthermore, both drugs were fully released from the nanofibers within 48 hours. In contrast, FA/LDC-loaded PVP nanofibers exhibited EE% of 100% for FA and 84% for LDC; DL was measured at 85 ± 3 μg/mg for FA and 70 ± 3 μg/mg for LDC, while both drugs were completely released within 24 hours. The in vitro cytotoxicity study demonstrated a safe concentration of FA and LDC at ≤ 125 μg/mL. The prepared nanofibers were tested in vivo in an S. aureus-infected wound mice model to assess their efficacy, and the results showed that the FA/LDC-PVP had a faster wound closure and the lowest bacterial counts compared to other groups.Conclusion: These findings showed the potential application of the fabricated dual drug-loaded nanofibers as a wound-healing plaster against infected acute wounds.Keywords: electrospinning, nanofibers, fusidic acid, lidocaine, wound healing, infected wound |
