| Message: | The Development of PT-141:
PT-141 was developed from the Melanotan 2 Peptide, which underwent testing as a sunless tanning agent. In initial testing, Melanotan 2 did induce tanning, but additionally caused sexual arousal and spontaneous erections as unexpected side effects in nine out of the ten original male volunteer test subjects. Palatin completed patient treatment in its Phase 2B clinical trial in premenopausal women with FSD Primary data analysis and announcement of top-line results anticipated in first-half of fourth quarter of calendar year 2012. In studies, PT-141 was shown to be effective in treating sexual dysfunction in both men (erectile dysfunction or impotence) and women (sexual arousal disorder). Unlike Viagra and other related medications, it does not act upon the vascular system, but directly increases sexual desire via the nervous system.
Description:
Bremelanotide (formerly PT-141) is a compound under drug development by Palatin Technologies as a treatment for female sexual dysfunction, hemorrhagic shock and reperfusion injury. It functions by activating the melanocortin receptors MC1R and MC4R, to modulate inflammation and limiting ischemia. It was originally tested for intranasal administration in treating female sexual dysfunction but this application was temporarily discontinued in 2008 after concerns were raised over adverse side effects of increased blood pressure. As of March, 2012, Palatin is conducting a human Phase 2B study using a new subcutaneous drug delivery system that appears to have little effect on blood pressure.
Bremelanotide or PT-141 is the generic term for a new research peptide for use in helping improve sexual dysfunction in men (erectile dysfunction or impotence) as well as helping improve sexual dysfunction in women (sexual arousal disorder). Bremelanotide, PT-141 does not act on the vascular system like the former compounds but it is known and has been shown to help increase sexual activity in both male and female mammals. |
