What is the Origin of PT-141 Efficacy?

PT-141 is a synthetic analog of alpha-melanocyte-stimulating hormone ($alpha$-MSH), initially developed from the peptide Melanotan II. The term "efficacy" is a standard clinical measure, derived from the Latin efficacia, meaning "effectiveness."

What is the Mechanism of PT-141 Efficacy?

PT-141 efficacy is mediated by its agonistic activity at central melanocortin receptors, specifically the MC3R and MC4R, located in the hypothalamus and other regions of the brain. Activation of these receptors modulates neural pathways associated with sexual arousal and desire, distinguishing its mechanism from peripheral vasodilators. This central neuroendocrine action bypasses vascular issues, offering a unique pharmacological approach to addressing the complex hormonal and neurological basis of sexual response.

PT-141 Efficacy

Meaning

The demonstrated capacity of the synthetic peptide PT-141 (Bremelanotide) to produce a desired therapeutic effect, specifically the treatment of hypoactive sexual desire disorder (HSDD) in premenopausal women and erectile dysfunction in men. Efficacy is measured by clinical trials assessing objective and subjective improvements in sexual desire and function. The peptide represents a novel, central-acting approach to sexual dysfunction.
