Optimization & design of isradipine loaded solid lipid nanobioparticles using rutin by Taguchi methodology.

Our research objective was to optimize and design nano-biosystem of Isradipine (IDP) via novel bioenhancer (Rutin) loaded solid-lipid nanobioparticles (ANbp) using Taguchi design (TgD) methodology. Firstly, preliminary screening of solid lipid nanoparticles (SLNps) formulation core factors (A, B & C; Lipoid's, poly-acid, sonication time respectively at fixed dose of model drug were assessed on entrapment efficiency & particle size; R1 & R2) by performed experimentally of three factor three levels orthogonal L27 array. Consequently, signal to noise (S/N) ratio plot of responses were drawn to predict better quality fitted-levels of significant factor for eminence optimization. Further, optimized quality spaces composition was used via enhancer (Rutin) to design advanced bio-formulation (ANbp) and done its evaluation (entrapment efficiency, particle size, drug release & kinetics). As designed, ANbp results showed better sustained (86.54% as compared to control SLNps 94.48% in 24h) release, kinetics & stability behavior with good entrapment efficiency (97.58%) and desired smaller particle size (108nm). Therefore, statistically (TgD) optimization strategy would be considered to design nano-drug delivery system with bio-agent in-order to improve oral bioavailability of antihypertensive agents.
