Miconazole-loaded nanoparticles coated with hyaluronic acid (miconazole-loaded nanoparticles/HA) were developed to overcome the limitations of the conventional therapy of the vulvovaginal candidiasis (VVC). They were synthesized by emulsification and solvent evaporation techniques, characterized by diameter, polydispersity index, zeta potential, encapsulation efficiency, atomic force microscopy (AFM), evaluated in terms of efficacy against C. albicans in vitro, and tested in a murine VVC model. Nanoparticles showed 211nm of diameter with a 0.32 polydispersity index, -53mV of zeta potential, and 90% miconazole encapsulation efficiency. AFM evidenced nanoparticles with a spherical shape. They inhibited the proliferation of C. albicans in vitro and in vivo after a single administration. Nanoparticles released the miconazole directly in the site of action at low therapeutic doses, which was enough to eliminate the fungal burden in the murine VVC model. These systems were rationally designed since the existence of the HA induces their adhesion on the vaginal mucus and their internalization via CD44 receptors, inhibiting the C. albicans. Therefore, miconazole-loaded nanoparticles/HA represent an innovative non-conventional pharmaceutical dosage form to treat the VVC and recurrent VVC.

Background: Oral thrush is the most common occurring fungal infection in the oral cavity in uncontrolled diabetic patients, it is treated by various antifungal drugs according to each case. This study aimed to evaluate the therapeutic effects of topical application of miconazole and miconazole-loaded chitosan nanoparticles in treatment of diabetic patients with oral candidiasis.
Methods: In this randomized controlled clinical trial.

Background And Objective: Miconazole is a broad-spectrum antifungal drug that has poor aqueous solubility (<1 µg/mL); as a result, a reduction in its therapeutic efficacy has been reported. The aim of this study was to formulate and evaluate miconazole-loaded solid lipid nanoparticles (MN-SLNs) for oral administration to find an innovative way to alleviate the disadvantages associated with commercially available capsules.
Methods: MN-SLNs were prepared by hot homogenization/ultrasonication.
