Revolutionizing Pharmacotherapy: The Role of Nanosuspensions in Drug Delivery Systems

Nanosuspensions (NSs) are systems of colloidal particles that are nanoscale in size. This paper investigates how the characteristics of NSs are impacted by formulation and process conditions, as well as underlines current developments, new methodologies, and helpful advice for adapting NSs to diverse routes of administration. In the field of nanomedicine, they have quickly become one of the most fascinating materials. The low solubility of certain drug molecules poses a significant issue in formulating drugs. Drug NSs have arisen as a potential way to administer hydrophobic drugs. Reducing nanoparticles boosts drug solubility and availability in water by expanding the drug's surface area that interacts with biological fluids. NSs stabilized by steric polymers, such as polyethylene glycol (PEG), and ranging in size from 10 to 100 nm, are of special significance. With little collateral damage to healthy tissues, these nanoparticles may encircle tumors and infarct zones. Some commercially available nanosuspension methods include top-down and bottom-up procedures, media milling, emulsification, melt emulsification, high-pressure homogenization, and emulsification. Additional methods used to improve certain properties in advanced treatments include solidification and surface modification procedures performed after production. This review will first discuss techniques for preparing NSs. In conclusion, we emphasize common methods of character portrayal and various practical applications for designing drug delivery systems and utilizing different routes of administration including, pulmonary, parenteral, oral, and ocular routes.
