Huperzine A micro-emulsion type cataplasm

The invention discloses huperzine A micro-emulsion type cataplasm which mainly consists of a medicament storage layer, a non-woven cloth back lining layer and an anti-adhesive layer, wherein the medicament storage layer is arranged between the non-woven cloth back lining layer and the anti-adhesive layer; and the medicament storage layer comprises huperzine A, oil, a surfactant, a cosurfactant, an absorption enhancer, a cataplasm aqueous matrix and distilled water. According to the huperzine A micro-emulsion type cataplasm, the huperzine A is uniformly dispersed in the cataplasm aqueous matrix in a micro-emulsion state and is matched with a skin penetration enhancer. Compared with a skeleton type huperzine A slow-release paster which takes polyacrylate as the matrix, the huperzine A micro-emulsion type cataplasm overcomes the following significant defects: firstly, the irritation is reduced, secondly, the toxicity is low, thirdly, the permeation rate is improved, and fourthly, the rare resource is saved; moreover, the exploration of rare plants is reduced.
