Development, Characterization, and Evaluation of Anti-fungal activity of Nystatin loaded Nanogel
Authors
Abstract
Nystatin has been used as a fungal inhibitor. Nystatin is applied topically since the
oral method of delivery irritates the gastrointestinal tract and can cause ulcers. The antifungal
nanogel used in this study was designed to optimize in-vitro release and in-vivo release
investigations while also reducing particle size. Using a homogenization process with carbopol
940 added as a gelling agent, Nystatin nanogels were created, yielding a smooth antifungal
nanogel (F1-F6). Fourier transform infrared analysis of antifungal nanogels (F1–F6) revealed no
interactions between the medication and excipients. The optimal formulation (F6) produced a
high in-vitro release of 84.43% after 8 hours; the resulting values for particle size and zeta-
potential were 230 nm and -27 mV, respectively. It was demonstrated by in-vitro release kinetic
models that formulation-F6 adheres to high regression coefficient value, r 2 0.9967, and first-
order kinetics. The optimal formulation (F6)'s scanning electron microscopy image shows that
there is no nanogel breakup. Nystatin was reported to have a differential scanning calorimetry
(DSC) thermogram of 166 oC. The physical mixture of carbopol 940 and Eudragit-S 100 was
discovered to have a DSC thermogram of 129°C and 218°C. The medication and excipients did
not interact, according to the DSC analysis of nanogel (F6). An in-vivo investigation using mice
revealed that the optimal formulation, F6, had a superior therapeutic effect for dermatitis. The
best formulation, F6, was determined to have improved dermatitis scoring and better in-vitro
medication release.
