PT-141 Cartridge for Injector Pen

🧬 Clinical Overview

What it is:

PT-141 (Bremelanotide) is a melanocortin receptor agonist that acts on the central nervous system to support sexual desire and arousal in both men and women. Unlike treatments that work primarily on blood flow, PT-141 works upstream in the brain, making it a distinct option for patients whose concerns are rooted in libido and arousal rather than circulation alone.

Mechanism of Action:

Activates melanocortin 4 receptors (MC4R) in the hypothalamus, a key region for sexual arousal pathways

Increases central dopaminergic activity associated with desire and arousal

Acts independently of the vascular pathways targeted by PDE5 inhibitors

Onset typically occurs within 45 minutes to 2 hours of administration
