A Pramipexole-loaded wound dressing was produced via electrospinning of cellulose acetate solution. The dressing with 3% Pramipexole concentration showed higher cell viability and improved wound healing potential in a rat model of diabetic wound.
In the current study, a Pramipexole-loaded wound dressing was produced via electrospinning of cellulose acetate solution. Pramipexole was added to cellulose acetate solution at 3, 5, and 10% w/w concentrations and then electrospun. The produced wound dressings were studied regarding their physicochemical and biological properties. Results of cell viability assay and cytoprotection studies showed that cellulose acetate wound dressings containing 3% w/w Pramipexole had significantly higher cell viability compared with other concentrations. The wound healing potential of dressings incorporated with 3% drug was studied in a rat model of diabetic wound. Study showed that the cellulose acetate/3% Pramipexole scaffolds had significantly higher percentage of wound closure, epithelial thickness, and collagen deposition compared with drug-free dressings and control group. Gene expression study showed that the drug-loaded wound dressings could reduce oxidative stress and alleviate inflammation at significantly higher extent compared with other groups.
