Mechanism of Action

PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone. It acts as a non-selective melanocortin receptor agonist, with primary research interest at MC3R and MC4R in the hypothalamus. Unlike PDE5 inhibitors acting on vascular smooth muscle, its mechanism operates through CNS pathways. FDA-approved in 2019 (Vyleesi) for hypoactive sexual desire disorder in premenopausal women; dual mechanism involves nitric oxide release and central arousal modulation.
