Description

Bremelanotide (formerly PT-141) was developed for the treatment of female sexual dysfunction, hemorrhagic shock, and reperfusion injury. Bremelanotide, a synthetic peptide analog of α-melanocyte-stimulating hormone (α-MSH) is an agonist at melanocortin receptors including the MC3R and MC4R, which are expressed primarily in the central nervous system. Bremelanotide originally was tested for intranasal administration in treating female sexual dysfunction but this application was temporarily discontinued in 2008 after concerns were raised over adverse side effects of increased blood pressure. It appears that development for hemorrhagic shock and reperfusion injury has been discontinued. Palatin Technologies licensed North American development and commercialization rights of bremelanotide to Amag in January 2017. In June 2018, the US Food and Drug Administration (FDA) accepted AMAG Pharmaceuticals’ new drug application for bremelanotide for treatment of hypoactive sexual desire disorder in premenopausal women. If approved, bremelanotide will be available as a self-administered, disposable subcutaneous auto-injector used in anticipation of a sexual encounter.
