Recent Advances in Drug Delivery Systems

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 switching to advances in the worlds of micro- and nanotechnology.

The recent advances in the peptide,protein drug delivery systems are PEGylation and Depo-foam technology. Cell-penetrating peptides (CPPs) act as cargo carriers and constitute current 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 so they are considered more efficient and provide new avenues for research and applications in life sciences.

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

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.
