PT-141
Bremelanotide
PT-141, also known as Bremelanotide, is a synthetic peptide that works through the central nervous system to enhance sexual desire. Unlike PDE5 inhibitors that act on blood flow, PT-141 targets melanocortin receptors in the brain to address the neurological component of arousal.

Why PT-141
Key Benefits
- Enhances sexual desire and arousal through central nervous system pathways
- Effective for both men and women
- Works through a different mechanism than PDE5 inhibitors
- May benefit patients who do not respond to traditional ED medications
- Available in multiple convenient delivery methods
The Science
How It Works
PT-141 activates melanocortin-4 receptors (MC4R) in the hypothalamus, triggering signaling cascades that influence sexual arousal and desire. This central mechanism of action differentiates it from peripherally acting agents.
Safety & Side Effects
Common side effects include mild nausea, flushing, and headache, which typically diminish with subsequent doses. PT-141 should not be used more than once in a 24-hour period. Patients with uncontrolled hypertension should consult their provider.
