PT-141

PT-141, also known as Bremelanotide, is a synthetic peptide used to treat sexual dysfunction, including hypoactive sexual desire disorder (HSDD) in women. It works by activating melanocortin receptors in the brain, which can increase sexual arousal. Unlike other treatments, PT-141 does not act on the vascular system but instead targets the central nervous system, making it distinct from medications like Viagra. It is typically administered as a subcutaneous injection.
