Abstract

OBJECTIVES: In this study, polymeric nanoparticles based on chitosan incorporating the antifungal miconazole nitrate were fabricated and testedin vivo using murine vulvovaginal candidiasis. METHODS: Nanoparticles prepared by the ionotropic gelation method presented 200 to 300 nm diameter and polydispersity indexes ranging from 0.2 to 0.4. The nanoparticles were prepared to incorporate 63.9 mg/mL of miconazole nitrate to be testedin vivo. Murine vulvovaginal candidiasis was standardized using estradiol valerate before the animals were challenged by Candida albicans. RESULTS: The treatment using chitosan nanoparticles within miconazole nitrate presented the same therapeutic efficacy as miconazole nitrate in a commercial cream formulation, however using the antifungal content about seven-fold lower. This increase in the miconazole nitrate's therapeutic efficacy is may be due to the down-regulation of interleukin 10 (IL-10) expression. CONCLUSIONS: Our data represent a proof of concept that can be exploited to achieve an alternative and promising therapy for the treatment of vulvovaginal candidiasis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
