Abstract
It is an objective to provide a microneedle and a microneedle array formed from a self-dissolving base which can realize higher absorption efficiency and a higher pharmacological availability. A preparationfor body surface application has two sections divided in the insertion direction, namely, an acral portionand a rear end portion. The acral portionis a section including a body surface insertion end, and holds a target substance soluble in base. The rear end portionis a section including a pressing end, and is formed mainly only from the base. The rear end portiondoes not hold the target substance. When the preparationfor body surface application is inserted into a body surface such as the skin, since the target substance is contained in the acral portion, even if part of the rear end side thereof is subsequently not fully inserted into the body surface, high absorption efficiency and high pharmacological effect can be realized where the actual dose of the target substance is not below the desired amount of the drug.
