Long-term stability of insulin glulisine loaded nanoparticles formulated using an amphiphilic cyclodextrin and designed for intestinal delivery.

Long-term stability is one of the main challenges for translation of therapeutic proteins into commercially viable biopharmaceutical products. During processing and storage, proteins are susceptible to denaturation. The aim of this work was to evaluate the stability of amphiphilic cyclodextrin-based nanoparticles (NPs) containing insulin glulisine.
