PT-141 is the prior developmental code given name for Bremelanotide. This is a peptide originally developed as a sunless tanning agent. It is a melanocyte-stimulating hormone (MSH) that affects sexual arousal, aiding enhanced libido levels and penile erections. Unlike Viagra or Cialis, PT-141 is not a PDES inhibitor, and it does not target the vascular system. Instead, it acts on the nervous system via activation of neurons in the hypothalamus to increase sexual desire.
Does PT-141 work?
A 52-week study monitored PT 141 use in premenopausal women with hypoactive sexual desire disorder and found that the treatment remained effective for the duration of the study.
Who should not take PT-141?
