Research Updates on Microneedle-Based Transdermal Drug Delivery Systems / 中国药学杂志

ABSTRACT

Microneedle-based transdermal drug delivery system refers to the use of microneedles piercing the stratum corneum of the skin to form tiny pores, through which drug absorption via the skin is enhanced with minimal pain sensation. As a novel drug delivery method, the microneedle technology can significantly improve the transdermal absorption efficiency of the drugs, especially hydrophilic drugs, as compared with using transdermal drug formulations alone. Thus the scope of applicable drugs for transdermal delivery are remarkably enlarged, the efficacy and bioavailability improved as well. Microneedle technology has developed rapidly in the field of transdermal drug delivery. In this paper, the recent representative literature on microneedle-aided transdermal drug administration home and abroad to present the latest progress in this field that was summarized.
