Results : N - methyl pyrrolidone ( NMP ) resulted as the best SPE : in addition , the critical factors influencing the PR diffusion through the human epidermis when loaded in the patch resulted in the matrix thickness ( X ( 1 ) , p = 0 . 0957 ) and PR content ( X ( 3 ) , p = 0 . 0004 ) which improved the flux ; conversely , NMP lacked its enhancement effect when loaded in the patch and the increase in its concentration ( X ( 4 ) , p = 0 . 006 ) affected the drug permeation through human epidermis .
