Quick Summary
The desire peptide — FDA-approved for female sexual dysfunction
Also called: Bremelanotide, Vyleesi
What is PT-141?
PT-141 (Bremelanotide) is a synthetic melanocortin receptor agonist that was originally developed as a sunless tanning agent (Melanotan II) before its sexual effects were discovered. It is the first and only FDA-approved non-hormonal treatment for hypoactive sexual desire disorder (HSDD) in premenopausal women (as Vyleesi). Unlike PDE5 inhibitors (Viagra, Cialis), PT-141 works centrally in the brain rather than through vascular mechanisms.
How It's Made
PT-141 is a cyclic heptapeptide analog of alpha-melanocyte stimulating hormone (alpha-MSH). It is produced via solid-phase peptide synthesis. The FDA-approved version (Vyleesi) is available as a subcutaneous auto-injector.
