Title:
BISOPROLOL-CONTAINING ADHESIVE PATCH
Document Type and Number:
WIPO Patent Application WO/2007/069661
Kind Code:
A1
Abstract:
A bisoprolol-containing adhesive patch which comprises a support and an adhesive
layer superposed on one side thereof. The adhesive layer is characterized by
comprising a branched C12-28 monohydric alcohol, a free bisoprolol
base, and a polyisobutylene-based pressure-sensitive adhesive. In this constitution,
the compatibility between the polyisobutylene-based pressure-sensitive
adhesive and the free bisoprolol base can be specifically heightened. As a result,
it is possible to incorporate the free bisoprolol base in a large amount. The pressure-sensitive
adhesive layer can be inhibited from suffering the bleeding of the free bisoprolol
base and have practically sufficient pressure-sensitive adhesive properties.
