Nanocrystals of the poorly water-soluble drugs is a promising strategy. To stabilize the drug nanocrystals, stabilizers are usually used; however, the use of common stabilizers is limited by weak stabilization effect and toxicological concerns for long-term treatment. The present work was aimed to investigate the potential of natural silk protein as novel stabilizer for nanocrystal of hydrochlorothiazide, which was a model drug. The nanocrystals of...
