Transdermal Patch

IMGL4470

The hydrogel patch is a modern cataplasm, which belongs to the transdermal drug delivery system. It is an external preparation made of water-soluble polymer material as the main matrix, adding medicine, and coating it on the non-woven fabric. The hydrogel patch was first used in Japan. Compared with the early muddy cataplasm, the matrix composition is significantly different. The matrix of the mud-like cataplasm is mainly a muddy substance mixed with grains, water, paraffin wax and kaolin, while the matrix of the hydrogel patch is a hydrogel prepared from a polymer material. The matrix of the hydrogel transdermal patch is a hydrogel prepared from a polymer material. Hydrogel is a compound system with a three-dimensional network structure, which is insoluble in water but swellable and can maintain certain mechanical properties. It has high water content, flexibility and good biocompatibility. Therefore, the hydrogel patch has unique advantages over the mud-like cataplasm.

The application of hydrogel patches in China is mainly focused on surgical diseases, such as muscle pain. With the improvement of preparation technology and the development of new materials, hydrogel patches have gradually begun to be used in the treatment of certain internal medical diseases and some health function, such as female hormone therapy, the release of estrogen, and the improvement of female sexual desire. Through the release of herbal essence, the purpose of breast enhancement is achieved. The hydrogel patch can also be used as a carrier for skin immunity. The hydrogel patch can enhance the permeation of protein through the skin without affecting the activity of the protein.
