A melanocortin-4 receptor agonist approved by the FDA as Vyleesi for acquired, generalized hypoactive sexual desire disorder in premenopausal women.

Mechanism of Action

Bremelanotide acts centrally on melanocortin receptors, influencing sexual motivation pathways rather than the peripheral vascular mechanisms of older ED drugs.

Research and Evidence

Registrational trials (RECONNECT program) demonstrated improvement in desire and distress endpoints supporting FDA approval in 2019.

Evidence in context: the Neuro, Nootropic, and Cosmetic Peptides class page collects the shared evidence themes and study-reading guidance for this category.

Safety and Side Effects

Labeled effects include transient blood-pressure and heart-rate increases, nausea, and flushing; it is contraindicated with uncontrolled hypertension and in patients at cardiovascular risk.
