The invention is intended to provide an adhesive patch which effectively inhibits the occurrence of oozing out or sticking out of the adhesive layer components from the exposed area of the adhesive layer of the adhesive patch during storage as well as the occurrence of oozing of bisoprolol or a salt thereof from the adhesive layer thereby preventing the reduction in drug content. The support, the release liner and the adhesive layer constituting the adhesive patch each are formed to have a rectangular planar shape and the entire adhesive patch are formed to have a rectangular planar shape, and a protrudent part is formed on the support-side surface of the adhesive patch at a corner thereof. In addition, the adhesive patch may be formed to have a middle part and a peripheral part, and the protrudent part may be formed at a corner of the rectangular middle part. Further, between the adjacent at least two protrudent parts, a connecting built-up part may be provided in which the thickness of the adhesive patch is smaller than the thickness of the adhesive patch in the protrudent part. In case where the release liner has a split part, the split part is made so as not to traverse the protrudent part.
本发明旨在提供一种粘贴剂,它能有效地抑制粘贴剂在储存期间从粘贴剂的粘合层暴露区域渗出或粘出粘合层成分,以及从粘合层渗出比索洛尔或其盐,从而防止药物含量减少。构成粘贴片的支架、离型衬垫和粘合剂层各自形成为矩形平面形状,整个粘贴片形成为矩形平面形状,并且在粘贴片的支架侧表面的一角处形成突起部分。此外,粘贴片还可以形成中间部分和外围部分,突起部分可以形成在矩形中间部分的一个角上。此外,在相邻的至少两个突起部分之间,可以设置一个连接内置部分,其中粘合剂贴片的厚度小于突起部分中粘合剂贴片的厚度。如果离型纸衬垫有分割部分,则分割部分不得穿过突起部分。
