PT141 (Bremelanotide) is a cyclic hepta-peptide lactam analog of alpha-melanocyte-stimulating hormone (alpha-MSH) that activates the melanocortin receptors MC3-R and MC4-R in the central nervous system. It is the generic term for a new medication for use in treating sexual dysfunction in men (erectile dysfunction or impotence) as well as sexual dysfunction in women (sexual arousal disorder). It is a synthetic aphrodisiac. Unlike Viagra and other related medications, it does not act upon the vascular system, but directly increases sexual desire.
