Microneedle: An Overview

The document provided an overview of microneedles as a novel transdermal drug delivery method. It highlighted the limitations of traditional methods like hypodermic needles and topical creams due to the skin's stratum corneum barrier. Microneedles create micron-sized channels in the skin, allowing drugs to bypass this barrier and enter systemic circulation more effectively. This technique was being applied in various fields, including vaccine and insulin delivery, and cosmetics. The document also discussed the challenges and obstacles in the development and market introduction of microneedle products, emphasizing their potential to improve patient compliance by offering a painless alternative to traditional methods.
