How PT-141 works, and what the research shows.
PT-141 (Bremelanotide) activates melanocortin-4 receptors in the brain.
Unlike Viagra/Cialis (which work on blood flow), PT-141 works on the central nervous system to enhance desire.
Effective for both men and women.
PT-141 (bremelanotide) was FDA-approved in 2019 under the brand Vyleesi for hypoactive sexual desire disorder (HSDD) in premenopausal women.
The RECONNECT trials showed statistically significant improvements in desire and reductions in distress vs placebo.
Kingsberg et al., Obstet Gynecol 2019Earlier studies in men with erectile dysfunction showed efficacy distinct from PDE5 inhibitors — PT-141 works centrally on melanocortin pathways rather than peripherally on vasodilation, making it useful in patients who don't respond to Viagra or Cialis or whose primary concern is desire rather than erectile function.
