PT-141, also known as Bremelanotide, is a melanocortin receptor agonist that acts centrally through the nervous system rather than on the vascular system. This makes it distinct from most other sexual wellness treatments. It was originally developed from Melanotan II and has since been studied and approved specifically for sexual dysfunction in women, with significant off-label interest for men as well.

At Hawaii Natural Medicine, PT-141 may be offered as part of a broader sexual wellness consultation, particularly for patients who haven't found success with conventional approaches or who prefer a non-hormonal option.
