Effects of intravaginal curcumin gels combined with electroporation on vulvovaginal candidiasis

Objective: To observed the effect of a curcumin-based vaginal gel combined with electroporation for the treatment of vulvovaginal candidiasis (VVC) caused by Candida albicans. Methods: Temperature-sensitive in situ gels (ISG) were prepared using poloxamers 407 and 188 as matrices. The mass ratio of poloxamer 407 and poloxamer 188 was 7:1 with a gelation temperature of approximately 29°C and gelation time of 2.5 min. Results: Electroporation increased the transmucosal permeability of the model drug, doxorubicin and improved the antifungal effects of curcumin. In vitro antifungal experiments showed that the number of fungal colonies in curcumin ISG combined with electroporation was lower than that in pure curcumin ISG. In vivo pharmacodynamic experiments showed that, compared to the model group, curcumin ISG with electroporation inhibited the growth of C. albicans, alleviated vaginal mucosal edema, and reduced the inflammatory response. Conclusion: Curcumin ISG combined with electroporation has substantial potential for the efficient clinical treatment of VVC.
