A synthetic cyclic analog of alpha-MSH; FDA-approved as Vyleesi for hypoactive sexual desire disorder in premenopausal women.
A non-selective melanocortin receptor agonist acting mainly on MC4 (and MC3) receptors in the hypothalamus and limbic arousal pathways. Unlike PDE5 inhibitors that work on peripheral blood flow, it modulates the central neural circuitry that generates desire itself, with downstream dopaminergic signalling.
