Background: Oral mucositis, one of the most common complications of 5-fluorouracil (5-FU) treatment, leads to several problems, including pain, diarrhea and malnutrition, and reduces the quality of life and subsequent treatments. Melatonin, a neurohormone with anti-inflammatory and antioxidant activities, was encapsulated in niosomes and embedded in a mucoadhesive gel formulation as a Melatonin Niosome Gel (MNG) to perform oral mucositis treatment.
Objective: This study aimed to investigate the effectiveness of MNG for the treatment of 5-FU-induced oral mucositis in mice.
Methods: Oral mucositis was induced in ICR mice by 5-FU and randomly assigned to receive daily applications of the topical oral MNG, a fluocinolone acetonide gel, a blank niosome gel, or no treatment for 5 days in comparison with a normal group. Average body weights, food consumption, and behaviors of the mice as well as microscopic histopathology, Fourier-Transform Infrared Spectroscopy (FTIR) analysis, proinflammatory cytokine levels, and oxidative stress markers of the tongues were monitored and collected after sacrifice. In comparison to the normal group, the average body weights of the 5-FU-MNG mice did not deviate from that of the normal group, nor was there a significant difference in the time to sleep or licking (p>0.05 for both parameters).
Results: In addition, the mice treated with MNG and fluocinolone acetonide did not show significantly different histopathological, FTIR, interleukin-1β or malondialdehyde (MDA) results in the tongues used as the oral tissue samples.
Conclusion: This leads to the conclusion that topical MNG potentially inhibits inflammation and lipid oxidative stress in 5-FUinduced oral mucositis.
