Abstract

The invention relates to the technical field of medicines, in particular to a medication system. An electret nanoparticle cutaneous penetration system comprises an isolated layer, wherein a drug-contained pressure-sensitive adhesive layer is arranged on the inner side of the isolated layer, an electret layer made of electret materials is arranged on the outer side of the isolated layer, and a controlled release film layer is arranged on the inner side of the drug-contained pressure-sensitive adhesive layer; the electret layer, the isolated layer, the drug-contained pressure-sensitive adhesive layer and the controlled release film layer are arranged in sequence from outside to inside to form a depot patch; tourmaline powder particles are distributed in the drug-contained pressure-sensitive adhesive layer. According to the electret nanoparticle cutaneous penetration system, the tourmaline powder particles are mixed into the drug-contained pressure-sensitive adhesive layer, so that the electret nanoparticle cutaneous penetration system has the advantages of promoting blood circulation of a human body, enhancing the vitality of cells, improving an electret electric field, replenishing mineral substance for the human body and the like.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a drug delivery system. Background technique [0002] The transdermal drug delivery system refers to a new dosage form that is administered on the surface of the skin so that the drug enters the systemic circulation through the skin at a constant rate or near a constant rate to produce systemic or local therapeutic effects. Its advantages are as follows: drug absorption is not affected by factors such as PH in the digestive tract, food, and transit time; avoids liver over-effect; overcomes adverse reactions caused by excessive blood concentration caused by excessive absorption; sustainable control of drug administration speed, flexible medication etc. [0003] However, the existing transdermal drug delivery systems often have defects such as restrictions on the molecular weight and polarity of the drug, and there are also problems such as difficult control of the drug delivery ...
