Abstract
Troxerutin (TXR), a naturally derived compound with diverse therapeutic potential, faces limitations in clinical efficacy due to poor bioavailability and rapid plasma clearance. This study focuses on troxerutin-loaded solid lipid nanoparticles (TXR-SLNs) and their physicochemical properties, intending to enhance drug release. TXR-SLNs were prepared via high-shear homogenization followed by ultrasonication, yielding optimized nanoparticles with an average size of 140.5 ± 1.02 nm, a uniform distribution (polydispersity index: 0.218 ± 0.01), and a stable emulsion (zeta potential: 28 ± 8.71 mV). The formulation exhibited 83.62% entrapment efficiency, indicating improved drug-loading capacity and extended drug release. Spectroscopic and thermodynamic analyses confirmed component compatibility. Despite a decline in entrapment efficiency induced by temperature after one month of storage at 23 °C, the formulation may retain acceptable stability. This study provides insight into SLNs as effective carriers for enhancing troxerutin’s release profile, motivating further in vivo investigations to optimize therapeutic interventions.
