Determination of Pickering Nanoemulsion by Eudragit Rl-100 Nanoparticle as Oral Drug Delivery for Poorly Soluble

Objective: The purpose of this research study was to develop Ketoprofen-loaded Pickering nanoemulsion with the help of polymeric nanoparticles [NPs]. The pickering nanoemulsion formulation is developed using Eudragit RL 100, which has the greater ability to stabilize the formulation as well as it better controls the release of drug upon oral administration.

Method: In the present study, Ketoprofen - loaded Pickering nanoemulsion were prepared using an ultrasonic emulsification process. For the preparation of the Nanoemulsion, an aqueous phase of the nanodispersion of nanoparticle is used while Captex -300 and drug premix is used as oil phase. The nanoemulsion is formulated by using a probe sonicator with different ratios of aqueous phase and oil phase. The preformulation study of polymer or drug is done by FTIR and DSC and the drug - polymer compatibility was confirmed by FTIR. The prepared formulation was evaluated for physical appearance, pH, Viscosity, In vitro drug release, Particle size, Zeta Potential, Polydispersivity index, and transmission electron microscopy and stability. The Formulation is optimized for the different concentrations of the aqueous phase and oil phase with concentrations of drug and polymer.

Results: All the prepared formulations show particle size in between 100-500nm hence it indicats formation of nanoemulsion. The zeta potential is -46mv which indicates good stability of formulation. The In vitro drug release shows maximum drug release i.e. 96.93% in 10 hrs which shows that the release of drug is prolonged due to formation of Polymer NPs.

Conclusion: Thus the drug release was significantly controlled and slowed down when nanoemulsion is formulated by using NPs in comparison with control. These results fulfilled the objective of the study. This study opens new prospects on the formulation of Pickering nanoemulsion.
