Thank you all

Analysis:

Taking skin as the portal of drug input into systemic circulation is an important breakthrough to the traditional concept of skin medication. At present, the research in this new field is very active. Membrane storage transdermal drug delivery system, skeleton controlled release transdermal drug delivery system, micro-reservoir controlled release transdermal drug delivery system and patch controlled release transdermal drug delivery system have come out one after another, which has aroused great concern in the medical field. The research of these new dosage forms involves overcoming the obstacles of human skin to drug dialysis and improving the bioavailability of drug transdermal absorption, which is also the key part of transdermal drug delivery system and the problem of poor curative effect of transdermal drug delivery for external use at present. The utility model adopts a novel structure of "breathable adhesive tape → impermeable layer → impermeable ring → drug carrier with far infrared effect → drug → covering film", which overcomes the problem of low bioavailability of traditional external plaster and patch. Moreover, the innovation of this dosage form is that the drug carrier is composed of ceramic powder with far-infrared radiation and some latest materials of metal and nonmetal oxides and metal salts that can enhance far-infrared radiation. Compared with various transdermal drug delivery forms on the market at present, the utility model has the following advantages:

1 contains carrier, which promotes local microcirculation and improves the bioavailability of the drug.

2, easy to use, no overflow, no pollution to clothes.

3. Avoid the first-pass effect of the liver and the interference of gastrointestinal factors.
