Bremelanotide,formerly known as PT-141, is a peptide drug which has been under development by Palatin Technologies as a treatment for female sexual dysfunction(FSD), hemorrhagic shock, and reperfusion injury. Bremelanotide was originally tested for intranasal administration in treating FSD but this application was temporarily discontinued in 2008 after concerns were raised over increased blood pressure seen with bremelanotide administration in some patients. As of December 2014, Palatin is conducting a human phase III study using a subcutaneousdrug delivery system that appears to have little effect on blood pressure.
