Bremelanotide is primarily used in the treatment of hypoactive sexual desire disorder (HSDD) in premenopausal women. It works by activating melanocortin receptors in the brain, which are involved in sexual arousal and desire. The drug is administered as a subcutaneous injection, typically on an as-needed basis, and is designed to be used shortly before anticipated sexual activity. Its mechanism of action helps to enhance sexual motivation and reduce distress associated with low sexual desire. Bremelanotide offers a therapeutic option for women who have not responded to other treatments or who prefer a non-daily medication. It is important to note that it is not intended for use in men or postmenopausal women, and its use should be guided by a healthcare professional.
