PT 141 cream is a topical formulation based on the artificially synthesized heptapeptide bremoratin. Its unique mechanism lies in bypassing the traditional dopamine pathway and directly acting as a melanocortin receptor agonist, precisely activating MC4R and MC1R in the central nervous system. Unlike PDE5 inhibitors that are used on demand, it stimulates sexual motivation at the source by regulating the sexual center in the hypothalamus. Therefore, it demonstrates unique advantages in addressing sexual arousal disorders. After penetrating the skin, the cream enters the systemic circulation and combines with relevant receptors across the blood-brain barrier, promoting the release of dopamine and norepinephrine. It does not rely on the nitric oxide pathway and has minimal impact on the vascular system. The transdermal administration method not only avoids the inconvenience of injection but also provides a more stable blood drug concentration, especially suitable for patients with cardiovascular risks or those with contraindications to oral medications. Current research mainly focuses on treating female sexual interest/arousal disorders and male erectile dysfunction. Its treatment paradigm starting from motivation provides a new neural regulation perspective for the field of sexual dysfunction.

PT 141 COA
With the increasing attention to sexual health and satisfaction in modern society, the research and application of sexual desire enhancers have gradually become a hot topic. PT 141 Cream, As a chemical known as the 'love hormone', it was originally developed by American researchers to treat sexual dysfunction and low libido. Compared with other traditional sexual desire enhancers, PT 141 improves sexual desire and satisfaction by directly acting on the brain's sexual desire and reward system, without the need for physical stimulation. However, the traditional application forms of PT 141, such as oral or injection, have problems such as low bioavailability, frequent administration, and significant side effects, which limit its widespread use. Micro needle array technology, as a new type of transdermal drug delivery system, has shown great potential in the field of biomedicine in recent years. The microneedle array consists of multiple tiny needle bodies that can puncture the stratum corneum of the skin, forming tiny channels to promote transdermal absorption of drugs. Compared with traditional transdermal drug delivery systems, microneedle arrays have the advantages of painlessness, non invasiveness, and high efficiency, which can significantly improve the bioavailability of drugs. Therefore, combining PT 141 with microneedle array technology is expected to solve the problems existing in the traditional application form of PT 141, improve its therapeutic effect and patient compliance.
Design and preparation of microneedle array
Design principles of microneedle array
