Recent Advances in Drug Delivery System

The goal of drug delivery systems is to deliver medications to specific target parts of the body through a medium that can control the therapy’s administration. To achieve this goal, researchers are turning to advances in the worlds of micro- and nanotechnology.

The recent advances in the peptide and protein drug delivery systems are PEGylation and Depo-foam technology. Cell-penetrating peptides (CPPs) act as cargo carriers and constitute a current hotspot in medical research. CPPs to transport hydrophilic macromolecules into cells, thus, assist to execute biological functions. CPPs do not destroy the integrity of the cell membranes, and are considered more efficient and safe and providing new avenues for research and applications in life sciences.

Biologics can be re-engineered for BBB transport with the use of molecular Trojan horse technology. 

Needle-free drug delivery systems are novel ways to introduce various medicines to patients. PowderJect Pharmaceuticals one of the first companies to develop a needle-free technology for injecting powdered drugs into the skin. Needle free devices can take the form of power sprays, edible products, inhalers, and skin patches

Organizations such as W.H.O. and C.D.C. (center for disease control) support the development of needle free insulin drug delivery.

Transdermal patches are user-friendly, convenient, painless and offer improved patient compliance.

Nano drug delivery systems such dendrimers, fullerence, nano pores, nanotubes, nano shells, quantum dots, , nanovaccines, revolutionized drug delivery systems. Thus nanomaterial can be used for strategic development of new drug delivery systems and reformulate existing.

 Anti-cancer drugs such as loperamide and doxorubicin bound to nanomaterial have been shown to cross the blood-brain barrier.

According to BCC Research the global market for advanced drug delivery systems was valued at $151.3 billion in 2013. This market is forecasted to reach nearly $173.8 billion in 2018, registering a 5-year compound annual growth rate (CAGR) of 2.8%.
