PT-141, also known as Bremelanotide, is a synthetic peptide developed as a melanocortin receptor agonist for the treatment of sexual dysfunction in both men and women. Unlike drugs that act on vascular pathways, PT-141 targets the central nervous system to enhance sexual desire and arousal, making it a novel option for individuals with low libido who may not respond to traditional hormone or PDE5-based therapies.
Applications
- Hypoactive Sexual Desire Disorder (HSDD) in women (FDA-approved)
- Low libido and sexual arousal issues in men and women
- Alternative treatment for erectile dysfunction (especially non-responders to PDE5 inhibitors)
- Enhancement of sexual satisfaction and motivation
- Off-label use in premenopausal women with reduced sexual drive
Mechanism of Action
Melanocortin Receptor Agonism: Binds to MC3-R and MC4-R in the hypothalamus to stimulate sexual arousal centers
Central Nervous System Targeting: Unlike PDE5 inhibitors, PT-141 acts via the CNS, not the vascular system
Neurotransmitter Modulation: Enhances dopamine and oxytocin signaling to improve desire and pleasure response
Key Research Studies
1. Female Sexual Dysfunction – Phase 3 Trial
- Findings: Improved sexual desire and satisfaction vs placebo in women with HSDD
- PMID: https://pubmed.ncbi.nlm.nih.gov/31675872/
2. HSDD in Women – Clinical Trial
- Findings: Increased sexual function; well-tolerated with nausea as the most common side effect
- PMID: https://pubmed.ncbi.nlm.nih.gov/29362639/
3. Safety and Efficacy in HSDD
- Findings: Low incidence of serious side effects, effective in improving sexual desire
- PMID: https://pubmed.ncbi.nlm.nih.gov/30703677/
4. RCT in Women with HSDD
- Findings: Significant improvement in sexual satisfaction and libido compared to placebo
- PMID: https://pubmed.ncbi.nlm.nih.gov/30263140/
5. Sexual Desire in Men
- Findings: Demonstrated benefits in male libido and erectile response, even in non-responders to traditional ED meds
- PMID: https://pubmed.ncbi.nlm.nih.gov/25345518/
6. Female Sexual Arousal
- Findings: Pre-sexual activity use led to greater arousal and satisfaction in women with HSDD
- PMID: https://pubmed.ncbi.nlm.nih.gov/30763424/
7. Erectile Dysfunction in Men – Preclinical/Clinical Studies
- Findings: Central nervous system effects show promise as alternative ED therapy
- PMID: https://pubmed.ncbi.nlm.nih.gov/24062352/
