Melanocortin agonist for sexual desire and arousal — men and women.

As-needed subcutaneous injection
Physician-supervised

Overview

PT-141 (bremelanotide) is a melanocortin-receptor agonist that acts centrally on desire and arousal. Unlike PDE5 inhibitors, it works through the CNS rather than vascular pathways.

Key benefits

  • Improves libido and arousal
  • Works centrally, not just vascularly
  • Effective in both men and women

How it works

Subcutaneous injection 45–60 minutes prior to intimacy; effect lasts 6–24 hours.

Mechanism

Agonist of MC3R/MC4R receptors in the CNS, modulating desire circuits.

Who is this for

  • Adults with low desire
  • Patients where PDE5 inhibitors alone are insufficient
  • Women with hypoactive sexual desire

Considerations & safety

Can cause transient nausea, flushing and blood-pressure elevation. Discuss with physician if cardiovascular disease.
