Risk management and statistical multivariate analysis approach for design and optimization of satranidazole nanoparticles.

Rapidly evolving technical and regulatory landscapes of the pharmaceutical product development necessitates risk management with application of multivariate analysis using Process Analytical Technology (PAT) and Quality by Design (QbD). Poorly soluble, high dose drug, Satranidazole was optimally nanoprecipitated (SAT-NP) employing principles of Formulation by Design (FbD). The potential risk factors influencing the critical quality attributes (CQA) of SAT-NP were identified using Ishikawa diagram.

Mechanistic investigation of biopharmaceutic and pharmacokinetic characteristics of surface engineering of satranidazole nanocrystals.

The designing of surface engineered nanocrystals for improved stability and bioavailability is a multivariate process depending on several critical formulation and process variables. The present investigation deals with formulation of stable nanocrystals of poorly soluble satranidazole (SAT) for improving dissolution rate and pharmacokinetic profiling. SAT has low polar surface area, high dose and dosing frequency.
