PT-141, the first in a new class of therapies called melanocortin agonists, works through a mechanism of action involving the central nervous system rather than directly on the vascular system. As a result,it may offer significant safety and efficacy benefits over currently available products, which belong to the class of phosphodiesterase-5 (PDE-5) inhibitors.
 PT-141 is nasally administered and is both non-invasive and fast acting. Importantly, PT-141 is not expected to be contraindicated in patients taking nitrates for the treatment of cardiovascular disease. Clinical studies have demonstrated PT-141 to be safe and effective and to improve patient experience.

PT-141 or Bremelanotide is the generic term for a research peptide being studied for its possible use in helping to improve sexual dysfunction in both men (erectile dysfunction or impotence) and women (sexual arousal disorder). PT-141 was developed from the tanning peptide Melanotan 2, which is a synthetically produced variant of a peptide hormone naturally produced in the body that stimulates melanogenesis that is known as alpha-Melanocyte stimulating hormone. MSH, activates certain melanocortin receptors in the process of exerting its effects. Indeed, MSH also exerts potent influence over lipid metabolism, appetite, and sexual libido. Resultantly, PT-141 has been shown in studies to exhibit libido-enhancing effects by activating the melanocortin receptors MC1R and MC4R, but not skin tanning. Melanotan 1 and Melanotan 2 have been researched for their use in protecting against the harmful effects of ultraviolet radiation from sunlight due to their melanogenesis-stimulating properties.

PT-141 is a potential remedy for the treatment of sexual dysfunction; specifically, male erectile dysfunction. Studies have shown that PT-141 does not act on the vascular system like former compounds, but allegedly works by activating melanocortin receptors in the brain, therefore helping increase ones sexual stimulation.
 PT-141 is a melanocortin based peptide that has shown effectiveness in clinical studies on both male and female rats. Male rats have shown erectile response with doses as low as 1-2 mgs whereas most female rats have shown positive results with higher doses around 2-3 mgs. While the dosage requirements tend to be higher for female rats, the observable results in female rats tend to be stronger.
