Title
(EN) IMPROVED TRANSDERMAL DEVICE HAVING DECREASED DELAMINATION
(FR) DISPOSITIF TRANSCUTANE AMELIORE A DELAMINATION DIMINUEE
Abstract
(EN)
A device for the transdermal administration of a drug comprising a microporous tie layer located between the drug reservoir and the contact adhesive. The tie layer eliminates blooming and delamination and has no appreciable adverse effect on either the drug flux or release rate from the device.
(FR)
Un dispositif, qui permet l'administration transcutanée d'un médicament, comprend une couche microporeuse de fixation placée entre la réserve de médicament et l'adhésif de contact. Cette couche de fixation élimine le colmatage et la délamination sans entraîner d'effet négatif notable sur l'écoulement du médicament ou le taux de libération propre au dispositif.
