Description:
Background: Minoxidil is an antihypertensive agent and vasodilator which may help to promote
local blood flow thus hastening the closure of excisional skin wounds. Corticosteroids may
down-regulate wound healing. This work aims to develop and characterize nanofiber-eluting
dexamethasone and minoxidil and investigate their effect on wound healing in a rat model.
Methods: Minoxidil and dexamethasone-loaded wound dressings were developed and
characterized with scanning electron microscopy (SEM) and Fourier transform infrared
spectroscopy (FT-IR). In vitro, drug release studies were performed for 12 days. To model the
wound-healing activity of the developed formulations, excisional wounds were created on the
dorsal section of male rats.
Results: All the electrospun wound dressing nanofibers displayed smooth structures and surfaces without drug crystals. Histological results of Hematoxylin & Eosin and Masson’s trichrome
staining indicate wound healing suppression in the dexamethasone-treated group and good
healing activity in the minoxidil-treated group. Here we identified that the application of topical
minoxidil can be effective for wound healing probably driven by the anagen hair growth while
dexamethasone suppresses collagen production and prevents scar formation.
Conclusion: The findings suggest that this minoxidil and dexamethasone wound dressing can
potentially be developed as a new treatment modality in the clinic to accelerate wound healing
while preventing scar formation.
