The transdermal patch contains a base layer, a textured pharmaceutical layer, and a detachable layer, sequentially stacked from top to bottom. The textured pharmaceutical layer contains pressure-sensitive adhesive and medicament, and is configured with at least an embossed pattern for contacting with the skin. After the detachable layer is peeled off from the textured pharmaceutical layer and the latter is attached to the skin, the transfer performance of the contained medicament is significantly enhanced by the embossed pattern's increased area of release to the medicament.
