PT-141
well-studiedA melanocortan receptor agonist that enhances libido and sexual arousal through central nervous system effects.
Overview
PT-141 (Bremelanotide) is a synthetic peptide derived from Melanotan II that acts on melanocortin receptors in the brain. Unlike traditional erectile dysfunction treatments that work through vascular mechanisms, PT-141 enhances sexual desire and arousal through the central nervous system.
Approved by the FDA as Vyleesi for treating hypoactive sexual desire disorder (HSDD) in premenopausal women, it has also shown efficacy in men. It works by activating melanocortin receptors (MC3R and MC4R) in areas of the brain involved in sexual response.
