Drug delivery

Transdermal drug delivery is impeded by the natural barrier of epidermis known as stratum corneum.This limits the route to transport of drugs with a log octanol–water partition coeffcient of 1 to 3,molecular weight of less than 500 Da and melting point of less than 200°C.Nanotechnology has received a widespread investigation as the nanocarriers are able to fuidize the stratum corneum as a function of size,shape, surface charges,and hydrophilicity–hydrophobicity balance, while delivering drugs across the skin barrier.This presentation provides an overview on the transdermal drug delivery performances of liposomes,ethosomes,transfersomes, niosomes,magnetosomes,oil-in-water nanoemulsions,waterin-oil nanoemulsions,bicontinuous nanoemulsions,covalently crosslinked polysaccharide nanoparticles,ionically crosslinked polysaccharide nanoparticles,polyelectrolyte coacervated nanoparticles and hydrophobically modifed polysaccharide nanoparticles with respect to their ability to fuse or fuidize lipid/protein/tight junction regimes of skin.Universal relationships of nanocarrier size,zeta potential and chemical composition on transdermal permeation characteristics of drugs will be discussed[1].

In recent years,the microwave is found to be able to exert spacing of lipid architecture of stratum corneum into structureless domains and promote transdermal drug delivery[2,3]. It is able to act as a radiation permeation enhancer and work synergistically with the chemical permeation enhancer such as oleic acid to promote transdermal drug delivery.The performance of microwave as transdermal permeation enhancer is challenged by the type of dosage form applied on skin,where the recent fndings indicate that polymeric macromolecules from semisolid samples can act as a binder to the intercellular spaces created by microwave,thereby leading to reduced drug permeation.The presentation will highlight the latest fndings of microwave enabling transdermal nanocarrier and drugdelivery.Microwave is reckoned to be the next generation technology in transdermal delivery.More research and development works are required to examine its worth in drug delivery with respect to the advances of nanotechnology and biologics.
