    The treatment of vulvovaginal candidiasis (VVC) is based on oral and vaginal formulations which show limited effectiveness. In this study, amphotericin B-loaded Eudragit RL100 nanoparticles coated with hyaluronic acid (AMP EUD nanoparticles/HA) were developed to overcome the drawbacks of the conventional formulations. AMP EUD nanoparticles/HA were synthesized by nanoprecipitation, formulated by statistical experimental design, and characterized. AMP release from EUD nanoparticles/HA and its antifungal activity in a murine model of VVC were evaluated. Nanoparticles showed 147.6 ± 16.7 nm of diameter, 0.301 ± 0.09 of polydispersity index, - 29.9 ± 3.76 mV of zeta potential, and 87.27 % of encapsulation efficiency. They released about 81 % of AMP in 96 h; and provided the elimination of 100 % of the vaginal fungal burden in 24 h. It was suggested that the AMP EUD nanoparticles/HA penetrated into the vaginal epithelium via CD44 receptors. These AMP EUD nanoparticles/HA represent a non-conventional vaginal formulation to improve the treatment of VVC.

    Data described in this article are related to the research article entitled “Amphotericin B-loaded Eudragit RL100 nanoparticles coated with hyaluronic acid (AMP EUD nanoparticles/HA) for the treatment of vulvovaginal candidiasis” [1]. In this work, we report original data on the statistical experimental design to formulate uncoated AMP EUD nanoparticles, data on the validation of spectrophotometric method to quantify the AMP released from uncoated EUD nanoparticles and coated with HA to obtain the in vitro drug release profiles as well as the drug encapsulation efficiency. In addition, we describe original data on characterization, including diameter size, polydispersity index, zeta potential, FTIR, DSC/TG, and XRD; data on diameter of in vitro inhibition halos of Candida albicans; and on the vaginal burden of infected animals treated with uncoated AMP EUD nanoparticles and AMP EUD nanoparticles/HA. Finally, different histological sections of endocervix collected from treated and untreated animals were inserted into this manuscript.
