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.

Current Research Focus

Primary Research Areas:

  • Hypoactive Sexual Desire Disorder (HSDD) in women (FDA-approved indication)
  • Low libido and sexual arousal disorders in men and women
  • Alternative treatment for erectile dysfunction (especially PDE5 inhibitor non-responders)
  • Enhancement of sexual satisfaction and motivation
  • Off-label investigation in premenopausal women with reduced sexual drive
Mechanism of Action

1. Melanocortin Receptor Agonism: Binds to MC3-R and MC4-R receptors in the hypothalamus to stimulate sexual arousal centers.

2. Central Nervous System Targeting: Acts primarily through the CNS rather than the vascular system, distinguishing it from PDE5 inhibitors.

3. Neurotransmitter Modulation: Enhances dopamine and oxytocin signaling pathways to improve sexual desire, arousal, and pleasure response.

Key Research Studies

1. Female Sexual Dysfunction – Phase 3 Trial

  • Findings: Improved sexual desire and satisfaction compared to placebo in women with HSDD
  • PMID: 31675872

2. HSDD in Women – Clinical Trial

  • Findings: Increased sexual function; generally well tolerated, with nausea as the most common side effect
  • PMID: 29362639

3. Safety and Efficacy in HSDD

  • Findings: Low incidence of serious adverse effects; effective in improving sexual desire
  • PMID: 30703677

4. Randomized Controlled Trial in Women with HSDD

  • Findings: Significant improvement in sexual satisfaction and libido versus placebo
  • PMID: 30263140

5. Sexual Desire in Men

  • Findings: Demonstrated benefits in male libido and erectile response, including in non-responders to traditional ED medications
  • PMID: 25345518

6. Female Sexual Arousal Enhancement

  • Findings: Pre-activity administration led to greater arousal and satisfaction in women with HSDD
  • PMID: 30763424

7. Erectile Dysfunction in Men – Preclinical and Clinical Studies

  • Findings: Central nervous system mechanism shows promise as an alternative ED therapy
  • PMID: 24062352
Biological Effects and Benefits
Sexual Arousal and Desire:
Influences central nervous system pathways involved in sexual motivation, stimulating brain regions that control desire and arousal rather than directly affecting blood flow.
Libido Boost:
Clinical studies show it can significantly increase sexual desire and improve the ability to achieve arousal in both men and women.
Biological Effects
Works Independently of Testosterone:
Operates through a distinct neurological mechanism, making it beneficial for individuals with low libido who may not respond to testosterone-based therapies.
