Abstract
Transdermal drug technology specialists are continuing to search for new methods that can effectively and painlessly deliver larger molecules in therapeutic quantities to overcome the difficulties associated with the oral route, namely poor bioavailability due to hepatic metabolism (first pass) and the tendency to produce rapid blood level spikes (both high and low). As all the drugs do not meet the physicochemical properties required for transdermal drug delivery. So, these techniques are required. Although addition of penetration enhancers increases permeation of drugs but that is not sufficient to ensure delivery of therapeutically effective concentration of drug therefore, several new active rate controlled TDDS technologies (drug and vehicle drug selection, vesicles and particles, Horney layer modified, Horney layer bypassed, Electrically driven and some other techniques) are being employed. This review article covers most of the new active transport technologies involved in enhancing the transdermal permeation into an effective DDS.
