摘要:
A product having a microneedle array is provided wherein the composition distribution has been adjusted with good accuracy. A droplet-delivery apparatus (10) of a microneedle-array manufacturing apparatus (1) is configured capable of delivering, to each recessed part, droplets of a raw-material liquid in a prescribed amount that is less than the capacity of the recessed part. An aligning apparatus (20) can align the relative position of the droplet-delivery apparatus (10) and a mold (80) such that the droplets from the droplet-delivery apparatus (10) are caused to land in each of the recessed parts. The droplet-delivery apparatus (10) delivers a plurality of the droplets to each of the recessed parts; and the aligning apparatus aligns the relative position of the droplet-delivery apparatus and the mold such that a second droplet lands in each of the recessed parts on the center part side of a first droplet.

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 .

A microneedle patch with which a treatment is reliably completed in a short time when a microneedle is administered into skin or mucous membrane is provided. A microneedle patch (100F) includes a base member (101) and a plurality of microneedles (103g) supported by the base member (101). Each microneedle (103g) includes a top-section layer (104) comprising a biologically active substance to be inserted in dermis (310), and an intermediate layer (106) provided between the top-section layer (104) and the base member (101), having a composition having breaking strength weaker than breaking strength of a composition of the top-section layer (104), and having a thickness of 5 µm and 100 µm inclusive.

A problem to be solved of the present invention is to provide a drug formulation and a method of administering an active ingredient which allow the active ingredient to be delivered evenly into the site of action in the skin with high efficiency while ensuring stability of the active ingredient over a long time, and which are easily handled and are less stressful for patients. Mean for solving the problem is a microneedle assembly formulation for skin treatment comprising a platform and a plurality of conical or pyramidal microneedles formed on the platform containing a base composed of a bio-soluble and thread-forming polymer substance and an objective substance retained in the base, wherein the objective substance is a substance effective for prevention or treatment of skin senescence, or treatment of skin scar.
