Design, Development and Characterization of Nisoldipine Solid Lipid Nanoparticles: Statistical and Characterization Perspectives.

Abstract

The objective of this study was to develop and characterize solid lipid nanoparticles (SLNs) loaded with Nisoldipine (NIS), aiming to enhance the drug’s bioavailability and provide a sustained release profile. SLNs were prepared using a solvent evaporation method and evaluated for several critical parameters. The superfluity test assessed the homogeneity of the SLN suspension, while particle size, drug entrapment efficiency, shapes, and surface morphology were analyzed using SEM/DLS/ TEM. Researchers studied the process of how drugs are released and performed in-vitro drug release tests to establish the substance’s release profile. HPLC and FT-IR were used to verify the drug’s chemical stability and encapsulation effectiveness. Stability studies assessed the formulation’s stability over time throughout different storage settings. The SLNs exhibited a high degree of homogeneity in the superfluity test, with no phase separation. The drug entrapment effectiveness was over 80%, and the typical particle size was 150-250 nm. Microscopy and transmission electron microscopy revealed that the SLNs had a flat, spherical top. NIS exhibited a regulated sequence of kinematics and prolonged release during dissolution investigations. FTIR and HPLC confirmed the stability and integrity of the drug within the SLNs. Stability studies indicated that the formulation remained stable over time. NIS-loaded SLNs show significant potential as an effective drug delivery system, offering enhanced bioavailability, sustained release, and excellent stability.
