This study investigates the efficacy of Phosphosulindac (OXT-328) in inhibiting human lung cancer growth in mice, particularly focusing on the enhanced delivery achieved through solid lipid nanoparticles (SLNs). The research highlights drug levels of Phosphosulindac and its metabolites across various organs following oral administration. Supplemental figures show analyses of TUNEL-positive and Ki-67-positive cells, illustrating the correlation between tumor drug concentration and cell proliferation/apoptosis markers. These findings suggest that targeted formulation enhances therapeutic outcomes in lung cancer treatment.
