PT-141, also called Bremelanotide, is a heavily modified synthetic derivative of alpha-melanocyte-stimulating hormone. It has been tested in clinical trials as a treatment for both male/female hypoactive sexual desire disorder and acute hemorrhage. PT-141 is an agonist for the melanocortin-4 and melanocortin-1 receptors. Research shows that it promotes sexual arousal and stimulates the immune system.

PT-141, also called bremelanotide, was previously investigated in phase Ilb human clinical trials for use in treating female hypoactive sexual desire disorder (HSDD). PT-141 is a melanocortin that binds primarily to melanocortin 4 receptor (MC-4R) and MC-1R. In 2009, PT-141 was also investigated as a treatment for acute hemorrhage. PT-141 is a derivative of another synthetic melanocortin, Melanotan 2 (MT-2).
