A mini review of nanosuspensions development.

Nanosuspension drug delivery has obtained great success in the preparation of insoluble drugs. The nanosuspension technology can confer a series of special characteristics to the drugs, such as the enhanced dissolution rate and saturation solubility. This mini review first described the differences between the nanocrystals and nanosuspensions. Next, the product techniques, the stable measures, the special features, and the routes of administration of the nanosuspensions were reviewed and compared. Finally, some existing shortcomings of the nanosuspensions were mentioned and the perspectives of the nanosuspensions were also made.
