Microneedle formulation administration member and microneedle formulation rapid administration device for placement of target substance in dermis

摘要

The problem of the invention is to provide a microneedle preparation administration apparatus that prevents overdosing caused by duplicate administration within a treatment range of skin, more reliably administers a prescribed dose of a growth factor at an intended optional depth in the dermis, exhibits an intended effect, and avoids pigmentation side effects. The solution to the problem is a microneedle preparation administration apparatus comprising: a guide tube; a pedestal in which at least a part thereof including a front end surface is housed within the guide tube and slides in length direction; and driving means for driving the pedestal toward a front end part of the guide tube, and microneedle preparations being to be attached to the front end surface of the pedestal, and the microneedle preparations being to be pressed out from a front end part of the guide tube, wherein the microneedle preparation has a first portion having a tip end part and containing an objective substance, and a second portion having a bottom part and not containing the objective substance, and the front end surface of the pedestal is struck on skin at a collision pressure of 30 N to 200 N per 1 cm 2 .
