| Summary: | Background: Chemotherapy is commonly used in oral cancer therapy, especially as the disease advances. However, it is associated with terrible adverse effects and the occurrence of chemoresistance which causes treatment failure. Thus, discovering a new potential anticancer agent and developing a safe, effective and non-invasive drug delivery are necessary. Objective: The objective of the current study is to develop ascorbic acid-loaded poly(lactic-co-glycolic) acid (AA-PLGA) nanoparticles incorporated into polyacrylic acid gel intended to treat oral cancer. Materials and methods: Double emulsion solvent evaporation method was used to
fabricate AA-PLGA nanoparticles. Optimisation was carried out in the primary emulsion based on multilevel factorial design by testing at varying surfactant types and concentrations. The optimised nanoparticles formulation was further incorporated into different concentrations of polyacrylic acid gel, and compared with a mucoadhesive polyacrylic acid-based commercial product (Kin Care) as a reference. The optimised AA-PLGA nanoparticles were subjected to cytotoxic assay against the SCC-25 cell line. Results: For the optimised formulation, we observed particle size of 252 ± 2.98 nm, polydispersity index (PDI) of 0.151 ± 0.02, zeta potential of -20.93 ± 0.87 mV, and encapsulation efficiency of 69.73 ± 1.07%. Polyacrylic acid polymer with a strength of 1% was chosen as the optimum gelling agent for AA-PLGA nanoparticles-in-gel formulation. Cytotoxicity study of the optimised nanoparticle demonstrated significant (p-value < 0.05) reduction of cancer cell viability in a dose-dependent manner with a half-maximal inhibitory concentration value of 2.42 mg/mL. Conclusion: The results of the present study support the feasibility of AA-PLGA nanoparticles-in-gel formulation for oral cancer therapy. |
