Embodiment

[0135] Hereinafter, although an Example is given and this invention is demonstrated in more detail, this invention is not limited at all by these Examples.

[0136] Patches of Examples 1 to 5 and Comparative Example 1 having the compositions shown in Table 1 were produced as follows.

[0137] The composition shown in Table 1 was weighed, ethyl acetate and heptane were added and mixed in larger amounts than the formulation, and a coating liquid was produced. Apply the coating solution on a silicone-treated PET film (release liner), dry it, evaporate the remaining part of the excess solvent, and attach the PET film side of the non-woven fabric laminated PET film (support) They were put on the plaster and laminated at 70° C. to obtain patches of Examples 1 to 5 and Comparative Example 1. The resulting patch was put into an aluminum laminated bag and sealed.

[0138] In addition, for each preparation, the paste with the release liner peeled off was exposed, and left at room temp...

Abstract

The present invention addresses the problem of accidents resulting from the misuse of adhesive patches, and provides an adhesive patch that is constituted from a support and a plaster, and exhibits characteristics for preventing said problem, wherein the plaster includes: a) an aliphatic compound that is a solid at room temperature and has a hydrophilic group; b) a non-aqueous pressure-sensitive adhesive; and c) a solvent that has a vapor pressure of 1 kPa or more at 20 deg C.

Description

technical field [0001] (Cross-reference to related applications) [0002] This application claims priority to Japanese Application No. 2017-183086 filed on September 22, 2017 (which makes a part of this specification by reference (clarification) as a whole. [0003] The present invention relates to a patch with non-repositionable function. Background technique [0004] In recent years, accidents caused by misuse of patches have increased. In the past, the drugs contained in the patches were topical drugs, usually anti-inflammatory drugs with low biological activity. However, the use of drugs with high systemic and / or physiological activity as active ingredients of patches is also increasing. Misuse of such patches can sometimes cause serious poisoning. Even when used as prescribed, patches contain a certain amount of medication. Poisoning accidents are sometimes caused by mistakenly attaching such a patch. In particular, young children sometimes attach patches used by ...
