Nano drug delivery has been designed to overcome these challenges due to the development and fabrication of nanostructures. It has been reported that nanostructures have the ability to protect drugs from the degradation in the gastrointestinal tract, the technology also allows target delivery of drugs to various areas of the body. The technology enables the delivery of drugs that are poorly water-soluble and can provide means of bypassing the liver, thereby preventing the first-pass metabolism. Nanotechnology increases oral bioavailability of drugs due to their specialized uptake mechanisms such as absorptive endocytosis and is able to remain in the blood circulation for a longer time, releasing the incorporated drug in a controlled fashion leading to fewer plasma fluctuations and minimizing side-effects.
