Description
PT-141, also known as Bremelanotide, is a synthetic peptide derived from the melanocortin hormone α-MSH. Unlike other compounds that act on the vascular system, PT-141 works directly on the central nervous system by activating melanocortin receptors (MC3R and MC4R) in the brain.
PT-141 has been studied for its ability to:
Enhance sexual arousal and desire by stimulating central melanocortin pathways — effects shown in both male and female preclinical and clinical models.
Support erectile function without relying on the nitric oxide pathway, making it distinct from PDE5 inhibitors like sildenafil.
Improve sexual function and satisfaction in models of hypoactive sexual desire disorder (HSDD) and sexual dysfunction.
Modulate neuroendocrine activity, influencing hormone release and energy balance in the hypothalamus.
Potentially impact appetite and metabolic regulation via MC4 receptor activity.
