Description

Quick Facts

Bremelanotide’s primary mechanism of action involves the activation of melanocortin receptors, predominantly MC4R, located in specific regions of the central nervous system, particularly in the hypothalamus and other areas involved in sexual arousal and desire. Unlike peripheral vasodilators used for erectile dysfunction, PT-141 does not directly act on vascular tissue; instead, it works upstream in the brain:

• MC4R Activation: By activating MC4R, Bremelanotide initiates a cascade of neuronal events that modulate pathways involved in sexual arousal and desire. This includes influencing dopaminergic and oxytocinergic systems, which play key roles in sexual motivation and response.
• Central Nervous System (CNS) Action: Its action is centrally mediated, meaning it affects brain pathways responsible for libido and arousal, rather than directly impacting genital blood flow. This makes it distinct from treatments that focus solely on physiological mechanisms.
• Modulation of Sexual Response: The precise neurochemical changes orchestrated by MC4R activation are thought to enhance the brain’s natural pro-sexual signaling, leading to increased sexual desire and arousal.

• Female Sexual Dysfunction (FSD): A primary area of research, particularly for Hypoactive Sexual Desire Disorder (HSDD) in premenopausal women, where it aims to increase sexual desire and reduce associated distress.
• Male Erectile Dysfunction (ED): Investigated for its potential in treating erectile dysfunction, especially in cases where traditional phosphodiesterase-5 (PDE5) inhibitors are ineffective or contraindicated, due to its central mechanism of action.
• Sexual Arousal Disorders: Broader research into its applications for various sexual arousal difficulties in both sexes by modulating central pathways.
• Neurobiology of Sexual Behavior: Used as a pharmacological tool to further understand the complex neural circuits and neurochemical systems that regulate sexual motivation, desire, and response.
• Melanocortin System Research: Contributes to understanding the specific roles of MC3R and MC4R in behavior, energy balance, and other physiological processes, distinct from the pigmentary effects of MC1R.
