Abstract

The aim of this research was to develop a nanosuspension of aprepitant (APT) using the Nano-by-Design approach. A novel microfluidization technology was used for processing the formulation. A 32 full factorial design was used for the optimization of dependent variables, which included critical quality attributes like particle size and polydispersity index. Subsequently, the design space was generated and the optimum formulation was located using desirability constraints followed by its validation.The prepared nanosuspension had a particle size of 721 nm ± 5%, a polydispersity index of 0.106 ± 3%, and a zeta potential of - 8.06 ± 5 mV. Its surface morphology was studied using SEM, DSC, and XRD. It revealed that the prepared nanosuspension had a nano-crystalline nature. The process parameters did not lead to any physicochemical interaction between the drug and excipients. This was confirmed using FTIR analysis. In vitro dissolution studies revealed 100% cumulative drug release over 60 min, showing better results in comparison with pure APT. Thus, it has been shown that microfluidization can be an industrially feasible, novel, green technology for the preparation of a stable APT nanosuspension for improving the dissolution profile of the drug.
