About PT-141

PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin receptor agonist derived from the tanning peptide Melanotan II. It acts centrally via MC3R and MC4R receptors in the hypothalamus, distinguishing it from PDE5 inhibitors that act peripherally. Preclinical and clinical research has studied its role in sexual arousal pathways, CNS-mediated desire signaling, and its potential in hypoactive sexual desire disorder (HSDD) models.
