§ 02 — Abstract
A melanocortin receptor agonist FDA-approved as Vyleesi for hypoactive sexual desire disorder (HSDD) in premenopausal women. Increasingly used off-label by men for libido and arousal.
PT-141 (bremelanotide) activates central melanocortin receptors (MC3R/MC4R) rather than the vascular pathway targeted by PDE5 inhibitors like sildenafil. It acts on the brain's sexual-arousal circuitry.
