The success of transdermal drug delivery has been severely limited by the inability of most drugs to enter the skin at therapeutically useful rates. Recently, the use of micron-scale needles in increasing skin permeability has been proposed and shown to dramatically increase transdermal delivery, especially for macromolecules. Using the tools of the microelectronics industry, microneedles have ...

Drug Delivery through skin would provide a useful alternative to oral delivery, which has numerous side effects. Therefore, the present investigation was aimed to develop sustained release transdermal therapeutics system containing Glipizide with varying ratios of HPMC & PVPK30 using solvent evaporation technique. Ten different formulations were prepared keeping the concentration of Glipizide c...
