Nanotechnology could be deliberately implemented in development of new drug delivery systems that can extend drug markets. Such a method would be applied to drugs selected for full-scale development based on their safety and efficacy information, but which fail to reach clinical development on account of poor bio pharmacological properties. The new drug delivery methods are required to enable pharmaceutical companies to reformulate existing drugs available, thereby expanding the lifetime of products and upgrading the performance of drugs by increasing effectiveness, safety and patient adherence, and finally lessening the healthcare costs.

Nanopharmaceutics refers to all aspects of nanotechnology-based pharmaceutics that applies to formulation, development and delivery aspects of pharmaceuticals. Nanomaterials (Nano size materials) that bring specific shapes and functionalities and nanodevices demonstrate a vital role in pharmaceutical nanotechnology. Nanopharmaceutics is the anticipation of healthcare and has gigantic promise.
