| Zusammenfassung: | Disclosed is a fentanyl-containing adhesive preparation for external use, wherein an adhesive layer is laminated on a supporting body. The adhesive layer contains a styrene-isoprene-styrene block copolymer, a tackifying resin that is composed of a rosin resin and a terpene resin, and a softening agent that is composed of a polybutene and a liquid paraffin. The adhesive layer also contains fentanyl as an active ingredient. The fentanyl-containing adhesive preparation for external use has excellent skin permeation of fentanyl and high preparation stability, without suffering from crystallization of fentanyl during storage. |
