Abstract: Solid Lipid Nanoparticles (SLNs) have emerged as promising drug delivery systems with the potential to enhance the therapeutic efficacy of bioactive compounds. In this study, T. Cordifolia extract-loaded SLNs were developed and characterized for their application in the treatment of autoimmune hepatitis. T. Cordifolia, known for its immunomodulatory and anti-inflammatory properties, was chosen as the active ingredient. The formulations were systematically evaluated for drug-excipient compatibility, particle size, zeta potential, drug loading efficiency, drug release kinetics, encapsulation efficiency, in-vitro release, and stability. The results indicated "No Change" in drug-excipient compatibility, ensuring the formulation's stability. The SLNs exhibited nanoscale particle sizes (159.30 nm to 172.12 nm) with narrow size distributions, facilitating consistent drug delivery. Negative zeta potentials (-28.28 mV to -35.44 mV) indicated colloidal stability. High drug loading efficiencies (up to 32.23%) and controlled drug release kinetics were observed, suggesting the potential for sustained and targeted drug delivery. Encapsulation efficiencies of up to 83.41% highlighted efficient drug loading within the SLNs. In-vitro release studies revealed that SLN2 and SLN4 exhibited superior drug release profiles compared to other formulations. These findings indicate the potential of these formulations for controlled drug delivery. In-vivo efficacy studies in murine models of autoimmune hepatitis are recommended to assess the therapeutic benefits of T. Cordifolia extract-loaded SLNs. Additionally, stability studies demonstrated the maintenance of critical parameters, such as particle size, zeta potential, and drug loading efficiency, under different storage conditions.
