PT-141
Melanocortin agonist researched for libido and arousal pathways.
PT-141
Background
PT-141 (bremelanotide) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone that acts as a non-selective agonist at melanocortin receptors, with activity at the MC4 receptor implicated in central regulation of sexual response. Unlike vasoactive agents, its proposed mechanism is centrally mediated within the nervous system.
Phase 3 trials (the RECONNECT studies) evaluated bremelanotide for hypoactive sexual desire disorder in premenopausal women, providing a controlled clinical evidence base for that specific indication.
