Abstract (en)

[origin: FR2755372A1] The device for ionophoresis combines a donor electrode assembly, a counter electrode assembly and a generator of electricity. The donor assembly comprises a primary reservoir element (11) containing the active principle and a secondary reservoir element (20) containing a neutral electrolyte, these reservoir elements being separated by a semipermeable membrane (17) in polymer material in contact with each of them, and an electrode (6) in contact with the secondary reservoir element. The polymer material of the membrane (17) consists at least in a polyetherblocamide with an <o>M</o>n between 10000 and 300000 and containing by weight, 35 % to 90 % of polyamide sequences. The invention is applicable to the transcutaneous administration of active principles to a subject with improved efficiency.
