Paper Title: In vitro-In vivo Correlations (IVIVC) of Amorphous Solid Dispersions for Nasal Delivery

Abstract
Amorphous solid dispersions (ASD) for nasal delivery offer the opportunity to increase drug release performance, while using polymers with mucoadhesive properties. In spite of the current knowledge on formulation and characterization of nasal powders, scarce studies evaluate the potential of ASD. Additionally, the lack of translation between different in vitro methodologies and the lack of correlations between in vitro and in vivo results compromise the accurate and effective development of nasal powders.听
Herein, spray dried ASD were manufactured and evaluated regarding in vitro drug release, ex vivo permeation and in vivo pharmacokinetic profile in Wistar rats. The results showed that ASD obtained by spray drying are able to improve drug release and permeation, ultimately resulting in faster drug absorption. This indicates that ASD for nasal delivery of poorly soluble drugs could be a suitable strategy to provide a faster onset of action. Additionally, the in vitro-in vivo correlations (IVIVC) between in vitro/ex vivo and in vivo pharmacokinetic parameters (tmax, Cmax and AUC1h), support the use of Franz diffusion cells to study drug release and permeation of nasal powder formulations.
听
Key learnings:
- ASD of poorly soluble drugs for nasal delivery are a suitable strategy to provide a fast onset of action;
- In vitro-in vivo correlations (IVIVC) are a valuable tool to support the use of in vitro methodologies as well as to guide formulation and process development.
