However, these treatments have limited efficacy in treating severe cases of OM. In this study, we aimed to develop a carbopol gel incorporating troxipide (TRO) nanoparticles and methylcellulose (TRO-NP gel) and demonstrate its efficacy in accelerating wound healing in a hamster model of OM (OM model) induced by acetic acid injection.Methods: TRO nanoparticles were prepared using bead milling. The crystalline form was determined by powder X-ray diffraction, and the particle size was measured using a NanoSight LM10 instrument. The drug release was determined using a Franz diffusion cell, and the hamsters injected with acetic acid were selected to evaluate the therapeutic effect of OM.Results: After preparing TRO nanoparticles, we observed a mixture of crystals and amorphous TRO, and the particle size of TRO in the TRO-NP gel ranged from 50 to 280 nm. The TRO-NP gel exhibited a more uniform TRO distribution and viscosity compared to the Carbopol gel containing TRO microparticles (TRO-MP gel). However, the solubility of TRO was comparable in both TRO-MP and TRO-NP gels. The TRO-NP gel released a higher amount of TRO than that from the TRO-MP gel, with detectable release of TRO nanoparticles. TRO levels in the cheek pouches of hamsters treated with TRO-NP gel were higher than those treated with TRO-MP gel. The increased TRO levels in the cheek pouches of hamsters treated with TRO-NP gel were attenuated by treatment with 40 μM dynasore, an inhibitor of clathrin-dependent endocytosis (CME). Moreover, the therapeutic effect of the TRO-NP gel was superior to that of the TRO-MP gel in the hamster model of OM.Conclusion: We have designed a TRO-NP gel, and this gel showed excellent TRO delivery into the cheek pouch tissue through the CME pathway. Moreover, the TRO-NP gel treatment enhanced wound healing after acetic acid injection. Keywords: troxipide, nanoparticle, oral mucositis, hydrogel, endocytosis |
