The drug-containing matrix layer contains a memantine alkali, an organic acid and an acrylic pressure-sensitive adhesive matrix, wherein the organic acid is a chain organic acid of C8-C18. The patch has less volatilization, does not crystallize, and can realize the long-term stable release of active ingredients. |
