    • A transdermal drug-containing dosage unit comprises: a backing layer substantially impervious to the drug to be delivered transdermally; a first polymeric adhesive matrix, in contact with the backing layer, having dispersed therein the drug and having a first delivery profile of the drug; a second polymeric adhesive matrix, in contact with said first polymeric adhesive matrix, having dispersed therein the drug and having a second delivery profile of the drug, wherein said second delivery profile is different from said first delivery profile; and a release liner in contact with the second polymeric adhesive matrix. The first polymeric adhesive matrix can release the drug more quickly or more slowly than the second polymeric adhesive matrix. Through the selection of the two matrices, the delivery profile of the drug through the skin can be selectively modified and controlled.
    • 含透皮药物的剂量单位包括:基本上不透过经皮递送的药物的背衬层; 与背衬层接触的第一聚合物粘合剂基质,其中分散有药物并具有药物的第一递送曲线; 与所述第一聚合物粘合剂基质接触的第二聚合物粘合剂基质,其中分散有药物并具有药物的第二递送分布,其中所述第二递送分布与所述第一递送分布不同; 以及与第二聚合物粘合剂基质接触的剥离衬垫。 第一聚合物粘合剂基质可以比第二聚合物粘合剂基质更快或更慢地释放药物。 通过选择两个基质,可以选择性地改变和控制药物通过皮肤的递送特征。
