Problems solved by technology

[0004] However, the existing micropatch requires different application times of the patch depending on the skin condition of the subject
In this case, as the attachment time of the micropatch increases, side effects such as skin irritation and inflammation are caused to the application target
[0005] Also, before the drug contained in the microstructure is absorbed into the skin due to sweating or an increase in body temperature, a part of the drug melts outside the skin and remains in the patch, so the amount of the drug delivered to the skin is uneven , unable to achieve the purpose of quantitative delivery

Abstract

A microstructure is provided. A microstructure according to an embodiment of the present invention comprises: a tip portion formed on a substrate and comprising a drug; and a separation portion which is formed between the substrate and the tip portion and, after the tip portion has been inserted into the skin, separates the substrate and the tip portion physically by means of an external force or chemically by means of a chemical material.

Description

technical field [0001] The present invention relates to a microstructure, in particular, to a microstructure that can be used to deliver medicine into the skin. Background technique [0002] Oral administration of tablets or capsules or needle administration is generally used to deliver drugs for disease treatment or cosmetics into the body. Recently, various microstructures including microneedles have been developed. The microstructures developed so far are mainly used for drug delivery in vivo, blood collection, and detection of analytes in vivo. [0003] The biodegradable microstructure does not dissolve immediately after being inserted into the skin, and it takes several minutes to tens of minutes to completely dissolve depending on the substance used. Therefore, in order to prevent the microstructures from detaching from the skin while the microstructures are being inserted into the skin and dissolved in the skin, a patch capable of being fixed to the skin is used. ...
