Announcing a new publication for Acta Materia Medica journal. Despite the advances in contraceptives, there is still a high rate of unintended pregnancies worldwide, due in large part to the lack of effective, convenient, and safe birth control methods. Compared with short-acting contraceptives, approaches that offer long-term pregnancy protection have attracted greater interest because of the reduced dosing frequency and improved patient compliance. As a novel transdermal drug delivery system, the microneedle (MN) patch has been widely used for a variety of biomedical applications, including long-acting contraception, due to unique properties, such as painless self-administration and elimination of biohazardous waste. In this article the authors provide a systemic review of MN patches that have been utilized for long-term contraception, including dissolvable MN patches, polymeric biodegradable MN patches, and silk fibroin-based biodegradable MN patches. The acceptability and biosafety of these contraceptive MN patches are also discussed. Finally, perspectives on the future clinical translation of MN patches for long-acting contraception are given.
