Etoposide-loaded lipid nanocarriers (ELNC) were developed and evaluated for their potential in treating cancer by improving the solubility, bioaccessibility, and controlled release of etoposide, a chemotherapeutic agent used primarily for small cell lung cancer and testicular cancer. Nanocarriers (ELNC-1, ELNC-2, ELNC-3) demonstrated particle sizes of 289–294 nm with a narrow polydispersity index, indicating uniformity and stability. Stability studies revealed a significant reduction in particle size under acidic conditions (pH 2.0), ensuring compatibility with gastric fluid, while an increase in size under alkaline conditions (pH 7.0) highlighted aggregation challenges. In vitro bioaccessibility studies showed a marked improvement for lipid nanocarriers compared to etoposide solution (ETS), with ELNC formulations achieving bioaccessibility of approximately 48% after 120 minutes. Drug release studies in simulated intestinal conditions exhibited a sustained release profile, with over 90% of etoposide released within 360 minutes. These findings suggest that ELNC can improve the therapeutic efficacy of etoposide by enhancing drug delivery in cancer patients. Further optimization to address intestinal aggregation is required to ensure stability and maximize therapeutic outcomes.
