PT-141, also known as Bremelanotide, is a medication used primarily for treating sexual dysfunction, specifically:
•Hypoactive Sexual Desire Disorder (HSDD) in premenopausal women
•Sometimes explored off-label for erectile dysfunction in men

PT-141 is a melanocortin receptor agonist, derived from the peptide hormone Melanotan II. Unlike other sexual dysfunction drugs (like Viagra), which work by increasing blood flow, PT-141 works on the nervous system — particularly the hypothalamus, which controls sexual arousal.
