PT-141
FDA APPROVEDMelanocortin receptor agonist | Sexual dysfunction treatment
Overview
What is PT-141?
PT-141 (bremelanotide) is a melanocortin receptor agonist approved by the FDA for the treatment of sexual dysfunction. Unlike traditional ED medications that work through vascular mechanisms, PT-141 directly influences the brain's sexual arousal pathways, making it effective for both male and female sexual dysfunction.
Key benefits
FDA-approved route with predictable absorption, works within 45 minutes and is effective for both male and female sexual dysfunction.
Mechanism of action
It acts in the central nervous system on the MC3R and MC4R receptors, directly influencing sexual arousal pathways, not through a vascular mechanism.
