How PT-141 + Oxytocin works, and what the research shows.
PT-141 (bremelanotide) activates a pathway in the brain that drives sexual desire, rather than acting on blood flow the way pills do.
Oxytocin acts on its own receptors and is studied for trust, bonding and the intensity of orgasm.
PT-141 on its own is approved as Vyleesi for premenopausal women with low desire and has been studied in men.
Kingsberg and colleagues, 2019Oxytocin's effects on intimacy come from smaller studies with mixed results.
The combination has not been trialed.
