The Role of Microneedle in the Transdermal Delivery of Insulin in Future Aspects

Microneedle (MN) transdermal insulin delivery aims to deliver painless insulin over the skin in a similar way to how transdermal patches, such as pain reliever patches and nicotine patches work. Insulin medication is currently effective in the handling of type 1 diabetes. If MN transdermal insulin administration can be performed successfully, it would present the possibility for people being treated with insulin to administer insulin without the need to place needles or cannulas (the very thin tube that supplies insulin to the body from insulin pumps) in the body. The MNbased drug delivery system can be achieved non-invasively or minimally invasive, which can add an advantage to painless, easy-to-handle, continuous delivery, and providing a controlled delivery system.
