Nanosized Model Drug Loaded Bio-Nano Suspension: Itandrsquo;s Development, Characterization and Evaluation

The objective of this research was to develop the phenytoin loaded bionanosuspension by using the novel biopolymer from Juglans regia. The different ratio of phenytoin and biopolymer (1:0.8, 1:1,1:2,1:3,1:4,1:5,1:8) were taken for preparation of formulations PJ1-PJ7. The bionanosuspension were evaluated for spread ability test, pH% entrapment efficacy, bio nanoparticles size in bionanosuspension, zeta potential, stability study and in-vitro drug release study. The formulation PJ2 with 1:1 drug biopolymer ratio was found to be best stable bionanosuspension on the basis of above evaluation parameters. The best formulation PJ2 showed the significant satisfactory results for different evaluations with t 50% of 18.09 hours and t 80% of 29.77 hours with r2 value of 0.9970. The best formulation PJ2 showed up to 86.56% ± 3 drug release in 36 hours. The bionanosuspension was found to be stable and safe for the delivery of Nano sized phenytoin using the isolated biopolymer having a unique stabilizer cum retardant property.
