3D printed microneedle for transdermal drug delivery application

Abstract

Microneedling is a relatively new treatment option in the drug delivery system as well as has been recognized for a broad range of applications like skin rejuvenation, acne scarring, rhytides, surgical scars, dyschromia, melasma, enlarged pores, and transdermal drug delivery. The role of three-dimensional printing as a fabrication technology for sophisticated transdermal drug delivery systems is explored in literature. 3D printing was proved to be an effective technology for the fabrication of biocompatible and scalable microneedle patches. Through this 3D printed microneedle device, injured or damage to tissue and organs are treated. As apparent from the continuous clinical preliminaries of a wide assortment of medications for different clinical conditions, there is an extraordinary future for the transdermal delivery of drugs. Therefore, this paper aims to explain an overview of the designing properties and methods for a 3D printed microneedle, and its uses and advantages in pharmaceutical applications. Future work will involve investigation of the use of 3D printed microneedle in the transdermal delivery of drugs among patients.
