摘要:
The present invention provides for transdermal delivery devices having microneedle arrays, as well as methods for their manufacture and use. In one embodiment, a transdermal delivery device is provided. The transdermal delivery device includes a polymer layer which has microneedles projecting from one of its surfaces. The microneedles are compositionally homogenous with the polymer base layer.

The present invention is drawn to a low-cost “meso” device that is able to effectively deliver functional self-delivery siRNA to subject and inhibit expression of a gene in the subject as well as related methods. In particular, a method of transdermally delivering nucleic acid material to a subject is provided. The method includes adapting a motorized meso machine for delivery of nucleic acid material; introducing nucleic acid material into a chamber of the motorized meso machine; and contacting the motorized meso machine to a skin surface of a subject for a period of time sufficient to deliver the nucleic acid material into the skin surface of the subject.
摘要:
Disclosed is a transdermal preparation, comprising sequentially-stacked layers of a backing layer, a barrier layer, a drug adhesive layer and a release layer, wherein the drug adhesive layer contains a drug selected from the group consisting of fentanyl, an analogue thereof and a pharmaceutically-acceptable salt thereof, a skin permeation enhancer of the drug, and a polyacrylate adhesive, which shows a high skin permeation with a low drug dosage, equivalent to one with high drug dosage, by increasing the skin permeation rate of drug.

A moisture-responsive film can include a complexing substrate and an iodine layer applied to the complexing substrate to form the moisture-responsive film. The moisture-responsive film can include a test area formed on a testing surface of the moisture-responsive film.
摘要:
A therapeutic toxin dosage form for treating a disease, disorder, or condition in a subject can include a microneedle array and a therapeutically effective amount of a therapeutic toxin loaded to the microneedle array for administration to the subject. Additionally, a method of treating a disease, disorder, or condition in a subject can include administering a therapeutically effective amount of a therapeutic toxin to the subject via a microneedle array.
摘要:
A method of treating or preventing keratin hyperproliferation skin disorders is set forth. The method includes the administration of an mTOR inhibitor to a subject afflicted with the hyperproliferation disorder. The mTOR inhibitor can be administered to the subject via any means known in the art including oral, topical, and transdermal administration.
摘要:
Methods of treating pain and/or itch in a targeted region of a subject and compositions and dosage forms therefor are described herein. Such methods can include topically administering a therapeutically effective amount of an mTOR pathway inhibitor to the subject.
摘要:
Microstructure manufacturing apparatuses and methods are disclosed herein that enable the production of microstructures in an efficient, cost-effective manner that produces precise, high-quality microstructure products. In the manufacturing process for a microneedle array, for example, a template can be contacted against a surface of a continuous layer of a viscous polymer and separated from the surface to form a plurality of projections. The projections can then be solidified and later cut at a predetermined distance from the surface to form the microstructure.

摘要:
An active agent can be administered transdermally to a patient by using a transdermal patch that has microneedles that are compositionally homogenous with a base layer. The transdermal patch can contain an active agent that can be delivered to a skin surface of a subject when the patch is applied.
