Formulation of Lipid Nanoparticles based Nanogel of Sertaconazole Nitrate and its Evaluation

Abstract

Background: Sertaconazole nitrate is a topical antifungal drug used to treat interdigital tinea pedis in patients with immunocompetent conditions. The class of imidazole includes the antifungal medication sertaconazole nitrate. It is available in topical formulations for treating skin infections, including athlete's foot. Solid lipid nanoparticles (SLN) are at the cutting edge of nanotechnology, with several potential uses in drug delivery and research. Because of their unique size-dependent features, lipid nanoparticles hold the promise of novel therapies. Objective: Drug incorporation into nanocarriers creates a new drug delivery prototype that could be employed for drug targeting. The research aims to study the formulation and evaluation of Sertaconazole nitrate solid lipid nanoparticles. The goal behind formulating SLN gel is to provide and maintain therapeutic concentrations of the drug at the target biological site to maximise therapeutic efficacy and minimise side effects. Methods: Sertaconazole Nitrate Solid Lipid Nanoparticles are prepared by using High Pressure Homogenizer to get nanogel formulation as the final formulation and In-vitro drug release using a diffusion apparatus. The prepared SLNs were evaluated in their FTIR studies to determine compatibility between the drug and the excipients; zeta potential indicates the solid lipid nanoparticle was stable, and polydispersity index was used to determine particle size. Result: The results demonstrate that optimised SLN-based Sertaconazole nitrate gel exhibited the best physicochemical properties, including FTIR studies of the drug, excipients, and optimised formulation demonstrate that all are compatible with each other, particle size is less than 200 nm, zeta potential ranging from 12 to -20 mV, and highest entrapment efficiency is 71.48%. Optimised solid lipid nanoparticles showed good in vitro release and antimicrobial results. The main application of SLN large scale-up is possible, and the drug can be effective with less dose incor-poration. Conclusion: In this research work, the proposed plan of work SLN of Sertaconazole Nitrate was formulated successfully. The preliminary identification tests were performed, such as melting point determination, estimation of λmax by UV-visible spectrophotometry and plot of its calibration curve in solvent and buffer system, and FT-IR investigation to confirm the purity and confirmation of medication. High physical stability and drug loading are advantageous to SLN.
