Comportamento eletroquímico e avaliação da difusão in vitro do α-tocoferol associado à iontoforese
Autor: Elisa Paludo, Laís Bresciani, Maurício Hilgemann, João Alberto Tassinary, Simone Stülp
Publikováno v: Química Nova, Vol 37, Iss 9, Pp 1469-1473 (2014)
Iontophoresis is a method of administering substances through the skin, which uses electrical current or potential to promote transdermal delivery. We focused on α-tocopherol (vitamin E), a natural antioxidant able to reduce or block the oxidation r
