The mechanism
PT-141 Acts on the Brain, Not the Vascular System
Bremelanotide is a synthetic neuropeptide that stimulates melanocortin 4 receptors (MC4R) in the hypothalamus. This triggers dopaminergic pathways that control sexual desire and arousal. Unlike PDE5 inhibitors that work on blood flow, PT-141 acts centrally on the nervous system. Intranasal delivery provides rapid absorption with onset in 15 to 30 minutes.

Regulatory context+
Bremelanotide was FDA-approved as Vyleesi in June 2019 for hypoactive sexual desire disorder in premenopausal women. This is a compounded intranasal formulation prepared under section 503A/503B in a licensed U.S. compounding pharmacy. It requires a prescription from a licensed healthcare provider.
Frequently asked
What is Bremelanotide (PT-141)?+
Bremelanotide is a synthetic neuropeptide that stimulates melanocortin receptors in the brain to support sexual desire and arousal. It acts on the central nervous system rather than the vascular system.
How does PT-141 differ from PDE5 inhibitors?+
PDE5 inhibitors work on blood flow and vascular mechanics. PT-141 acts centrally in the hypothalamus on melanocortin receptors, targeting the desire and arousal pathways directly. This makes it a different approach, particularly for psychological or hormonal causes of sexual dysfunction.
Does it work for both men and women?+
Yes. Bremelanotide has been studied for use in both men and women experiencing hypoactive sexual desire disorder (HSDD), arousal disorders, and psychogenic erectile dysfunction.
How quickly does it work?+
Typical onset is 15 to 30 minutes after intranasal administration, with effects lasting 4 to 8 hours.
How often can I use it?+
Maximum 1 dose per 24 hours. Your prescribing provider will determine the appropriate dosing frequency for your protocol.
What are the side effects?+
Common mild effects include nasal congestion, nausea, flushing, headache, fatigue, and temporary blood pressure increase. Consult your provider if any side effects persist.
Who should not use this product?+
Avoid use if you have uncontrolled hypertension, cardiovascular disease, or known hypersensitivity to melanocortin peptides. Not for use during pregnancy or breastfeeding, or with CNS stimulants.
How should I store it?+
Store in a refrigerator at 36 to 46 degrees F (2 to 8 degrees C). Do not freeze. Use within 30 days of opening.
Do I need a prescription?+
Yes. Bremelanotide Nasal Spray is a compounded medication that requires a prescription from a licensed healthcare provider.
Is this the same compound as the FDA-approved injection?+
Bremelanotide is the same active compound approved as Vyleesi in 2019. This is a compounded intranasal formulation with a different concentration and delivery method than the FDA-approved subcutaneous injection.
