Microneedle – Future prospect for efficient drug delivery in diabetes management.

This review aims at focusing on the use of microneedles (MNs) as an emerging novel drug delivery carrier for an effective treatment in diabetic patients. There are many limitations in various modes of delivery such as oral, subcutaneous, nasal, and other modes which cause pain and have many other side effects. Hence, this drug delivery research has found to have tremendous potential in combining both the diagnostic and therapeutic elements, thus treating diabetes in a better way. Most glucose-sensing techniques and conventional insulin therapies are engaged in the transfer of physical entities through the skin. MN- based drug delivery system can accomplish in an noninvasive or minimally invasive manner which can be an add on advantage towards pain-free administration, easy handling, discrete, continuous as well as providing a controlled release system. Hence, the review addresses on the current advancement of this bioengineered system like MNs, constituting a "smart" system specifically for autonomous diabetes therapy. [ABSTRACT FROM AUTHOR]
