    Abstract:
    The aim of the present study was to develop a novel formulation of berberine (BBR) and demonstrate its anti-seizure effect in pentylenetetrazole (PTZ) induced kindling model in rats. Nanoparticles of BBR were formulated using Poly Lactic-co-Glycolic Acid (PLGA) as a polymer. Emulsification and solvent evaporation technique was used. PTZ induced kindling model in male wistar rat was used to demonstrate the anti-seizure effect of nano-BBR. The particle size obtained for the final formulation was 242.8 ± 67.35 nm with a PDI of 0.140 ± 0.01. PLGA encapsulated BBR nanoparticles showed the % encapsulation efficiency of 87.33 ± 2.42 % and % drug loading of 48.47 ± 1.34 %. In-vitro drug release data showed sustained release of nano-BBR as compared to BBR. Kinetic study data showed increase in AUC of nano-BBR (35,429.46 h.ng/ml) as compared to BBR (28,211.07 h.ng/ml). Cmax for nano- BBR (2251.90 ng/ml) is approximately 1.6 times greater than BBR (1505.50 ng/ml). Nano- BBR has shown the significant effect on the seizure score. The PLGA encapsulated berberine nanoparticles were prepared by an innovative simple method and offers excellent potential as an antiepileptic agent.
