What is PT-141?
PT-141 can work when Viagra does not. It uses a different pathway than medications like Viagra. PT-141 is an exciting new option in addressing erectile dysfunction with the further benefit of increased arousal and libido. Also known as Bremelanotide, PT-141 is a melanocortin-stimulating protein that has proven beneficial in the treatment of mild-to-moderate erectile dysfunction [Diamond, et al. 2004].
Mechanism of Action
PT-141 binds to melanocortin receptors (MC3-R and MC4-R) in the hypothalamus in the brain. [Molinoff et al. 2003] Activation of these brain neurons has a direct erectogenic effect resulting in on-demand erections. The potency of the medication can last hours. The libido-enhancing effects of PT-141 typically last even longer.
Route of Administration
PT-141 is administered as a subcutaneous injection that can be easily injected into the abdomen. The small dose also makes traveling with PT-141 relatively simple. While the medicine is stable for long periods of time in a chilled environment, PT-141 is stable for 1 week at room temperature.
The most commonly occurring side effect is nausea. Other, less common side effects include flushing and headache. [Krapf, et al. 2016] Previously, PT-141 was tested by intranasal administration; however, this had the side effect of elevating blood pressure. By administering the medication through subcutaneous injection, the incidence of increased blood pressure dropped substantially.
PT-141 is currently FDA-approved for the treatment of female Hypoactive sexual desire disorder; however, current research has not yet caught up to its use in men. The limited body of research has demonstrated increased arousal and spontaneous erections.
