Abstract
Oral cavity cancer poses a significant health threat due to its aggressive nature and limited responsiveness to traditional therapies like chemotherapy and radiation, highlighting the need for more effective treatment options. To address this, researchers have explored a novel approach using niosome nanoparticles to co-encapsulate curcumin (CUR) and cisplatin (Cis), to enhance therapeutic efficacy. While CUR has anti-cancer properties, its poor bioavailability limits its effectiveness. Cis, on the other hand, is hindered by severe side effects and resistance. A dual-drug delivery system that encapsulates both CUR and Cis in niosome nanoparticles seeks to leverage the synergistic effects of these agents to improve treatment outcomes. The study synthesized Cis and CUR co-loaded nanoparticles (Cis/CUR-NPs) using reverse microemulsion and film dispersion methods, resulting in nanoparticles with an average size of 220.9 nm and a consistent size distribution. In vitro experiments demonstrated that the nanosized Cis/CUR-NPs could release both Cis and CUR, achieving a synergistic effect on OECM-1 cells at an optimal ratio (1:6) of the two drugs. Overall, the findings suggest that Cis/CUR-NPs offer a promising and effective strategy for leveraging the synergistic effects of Cis and CUR in treating oral cancer.
