Background: Drugs with poor solubility exhibit hurdles in their formulation due to poor dissolution and low bioavailability. Nanocrystallization is a great technique for incorporating poorly soluble drugs and is associated with many benefits.
Objective: The objective of the present review is to discuss formulation techniques for the generation of Nanocrystals (NCs) and illustrate the various advantages of NCs. It also explains commonly used stabilizers and guidelines for their safe use for enhancing NCs and provides a deep insight into various biomedical applications of NCs.
Methods: The review was extracted from the study carried out in the general literature to emphasize the importance of NCs in various formulations.
Results: NCs are a widely accepted approach to enhancing drug solubility. There are so many marketed products of nanocrystal drug formulations that are being used to treat life-threatening disorders. Two techniques can be used to formulate NCs, i.e., the bottom-up method and the top-down method. Their main biomedical applications are found in oral, parenteral, pulmonary, ocular, dermal, and mucosal formulations.
Conclusion: In the present review, different formulation methods of NCs have been discussed in detail, followed by explaining the advantages and various targeted drug delivery systems covered by NCs formulations. The development of NCs-based formulation avoids the limitations of other systems used for targeted drug delivery.
