Abstract (RBIP-24)

Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. Nanotechnology enhanced materials will enable a weight reduction accompanied by an increase in stability and an improved functionality. Traditionally nanotechnology in pharmacy has been associated with drug delivery, where the size of the delivery vehicle, whether it be a liposome, a polymer or even a metallic nanoparticle and its consequent ability to evade many of our bodies’ natural defenses has been the main attraction. We have recently seen the launch of the first nano-deliverysystem (DOXIL; Ortho-Biotech), a reformulated version of the anticancer agent doxorubicin. Here the drug is encased within polyethylene glycol (PEG)-coated liposome less than 200nm in diameter. Because of the sustained release of the drug from the liposome and its long circulation time from the “stealth” ability conferred by the PEG, intravenous treatment is only required every four weeks. The use o PEG to mask a drug from our natural defenses has also been used for antibody based therapeutics. Other delivery routes have also benefited. For example, VivaGel — a topical anti-HIV formulation — is one of the first drug products based upon nanoscale molecules called dendrimers (hyper branched polymeric macromolecules, 2–10nm in size). Looking ahead, a recent report suggests that the efficiency of inhaled drug delivery could be improved eight-fold using magnetic fields to guide drugs mixed with magnetic nanoparticles
