The conventional chemotherapy approach is associated with several drawbacks specifically detrimental adverse effects to the patient and occurrence of chemoresistance towards commonly used chemotherapy which further leads to treatment failure, disease recurrence and metastasis. The main objective of this study was to develop and characterise alternative potential anticancer ascorbic acid loaded PLGA nanoparticles gel for oral mucosa application for the treatment of oral squamous cell carcinoma. Ascorbic acid loaded PLGA nanoparticles were prepared by double emulsion solvent evaporation method followed by incorporation in different concentration of mucoadhesive Carbopol gel bases. The nanoparticles formulation were characterised for various physicochemical properties such as particle size, polydispersity index, zeta potential, encapsulation efficiency, drug-polymer interaction, nanoparticles morphology and in vitro drug release profile. Ascorbic acid nanoparticle loaded mucoadhesive gel were evaluated for physical appearance, pH, viscosity, flow behaviour, spreadability, mucoadhesion and in vitro release study. The particle size of the optimised nanoparticles was found to be 252 ± 2.98 nm, polydispersity index of 0.151 ± 0.02, zeta potential of -20.93 ± 0.87 mV and encapsulation efficiency of 69.73 ± 1.07%. Scanning electron microscope images revealed the spherical shape of nanoparticles. The drug release behaviour exhibited a biphasic pattern namely initial burst release followed by controlled release subsequently. The FT-IR result confirmed the absence of drug-polymer interaction. The optimised nanoparticle-in-gel formulation showed a good physical appearance, pH value, spreadability, viscosity and mucoadhesion. The flow behaviour of the optimised nanoparticle-in-gel formulation exhibited pseudoplastic behaviour. The cumulative amount of ascorbic acid released at 6 hours was 42.9 ± 4.3% with zero-order release kinetics. In conclusion, ascorbic acid loaded PLGA nanoparticle-in-mucoadhesive gel was successfully prepared and the study proved the potentiality and suitability of the formulation to be topically applied to treat oral squamous cell carcinoma.
