Description
PT-141, also known as bremelanotide, is a synthetic peptide medication used to treat hypoactive sexual desire disorder (HSDD) in premenopausal women and to support sexual function in men. It works by activating melanocortin receptors in the brain, which stimulates the central nervous system to increase sexual arousal and desire.
How PT-141 Works
Brain-Based Mechanism: Unlike other treatments that focus on blood flow, PT-141 targets the neural pathways in the brain that govern sexual desire.
Melanocortin Receptor Activation: It activates melanocortin receptors, particularly MC3R and MC4R, which play a key role in regulating sexual arousal and desire.
Stimulates Arousal: This brain-centered action enhances sexual desire and arousal, providing a more comprehensive approach to sexual dysfunction.
Uses
For Women: Approved for premenopausal women with HSDD who have troubling low sexual desire that isn’t caused by medical or relationship problems.
For Men: Used to support improved sexual performance, increase libido, and help address erectile challenges.
Side Effects
Common side effects of PT-141 include:
Flushing
Headaches
Nausea
Irritation and redness at the injection site
