More Information
Summary:In the adhesive pharmaceutical preparation of the invention, a pressure-sensitive adhesive layer is laminated on one side of the backing. The pressure-sensitive adhesive layer contains a branched monoalcohol having from 12 to 28 carbon atoms, a drug which is liquid at room temperature or around room temperature (in which, free base of bisoprolol is excluded) and a polyisobutylene pressure-sensitive adhesive. Accordingly, compatibility of the polyisobutylene pressure-sensitive adhesive with the drug can be specifically increased. As a result, not only it becomes possible to increase blending amount of the drug but also bleed of the drug from the pressure-sensitive adhesive layer can be suppressed and, what is more, the pressure-sensitive adhesion characteristics sufficient from the practical point of view can be obtained.
