Abstract: A container for an in vitro dissolution test of efficient components of a pharmaceutical topical patch includes a body having an open upper end. A mesh bottom cap is mounted to a bottom of the body. The mesh bottom cap includes a lower mesh. A mesh top cap has an upper mesh covering the upper end of the body. The pharmaceutical topical patch is retained in the body to avoid excessive expansion of the pharmaceutical topical patch due to excessive absorption of the reagent in a vessel, avoiding interference with stirring of a paddle in the vessel and providing accurate test results.

Abstract: A patch includes a support, an adhesive layer laminated on a face of the support, and a peeling film peelably attached to the adhesive layer. The peeling film includes two peeling film pieces that are connected by two connecting edges thereof. The connecting edges have a thinner and weaker structure than the remaining portions of the peeling film pieces. Alternatively, the connecting edges of the peeling film pieces are slightly bonded together. The respective peeling film pieces are easier to be peeled off from the adhesive layer, and the time for peeling is reduced. The risk of the user's hands in contact with the adhesive layer is greatly reduced. And the patch is easier to use for aged persons.
