Introduction:
Nanofiber (NF) films have emerged as a promising alternative for treating psoriasis. Based on their specific characteristics, they have distinguished themselves from other topical dosage forms, such as hydrogels, foams, and sponges. This research looks at making biocompatible and biodegradable nanofibers out of polyvinyl alcohol (PVA) and gelatin and adding hesperidin (HPN) and ofloxacin (OFX) as medicine.
Methods:
HPN-OFX-integrated nanofiber (HPN-OFXNF) films were prepared using electrospinning. Subsequently, the surface morphology, entrapment efficiency, in vitro drug diffusion, and antimicrobial, anti-inflammatory, and anti-psoriasis properties were investigated.
Results:
Scanning electron microscopy (SEM) analysis revealed that the produced nanofibers exhibited smooth surfaces with diameters from 50.67 to 114.4 nm, entrapment efficiencies from 69.3 ± 1.8% for OFX and 45.63 ± 1.6% for HPN. At the end of 48 h, nanofibers showed 90.8 ± 2.4% of OFX and 97.3± 3.1% of HPN release. In vitro, antimicrobial testing of the films demonstrated 24.89 ± 3.2 and 42.46 ± 4.4 mm zones of inhibition against E. coli and S. aureus. The total antioxidant activity of HPN is 198.67±2.38 (μ mol AAE/mg HPN), and HPN-OFXNF is 271.12 ± 3.56 (μ mol AAE/mg HPN-OFXNF), and their IC50 values against HaCaT cell growth of 80.5 ± 2.5 and 64.6 ± 3.4 μg/ml, respectively.
Discussion:
HPN-OFXNFs have been developed successfully by the electrospinning method with moderate entrapment efficiencies, showing a biphasic trend of an early burst trailed by a sustained pattern of drug release, depending on the surface area and diameter of the fibers. Enhanced zones of inhibition and anti-inflammatory efficacy of NFs in comparison with their pure counterparts have been demonstrated to be beneficial. Stronger antioxidant efficacy, inducing anti-proliferation and promoting apoptosis in human keratinocytes, has made them the best versions over pure drug compounds.
Conclusion:
This therapy, which includes a combined anti-inflammatory and antibacterial treatment strategy with an innovative drug delivery system, has proven to be a promising development in treating psoriasis.
