Product Overview

PT-141 (Bremelanotide) is a peptide therapy that may enhance sexual arousal and libido by activating melanocortin receptors in the brain. The PT-141/caffeine rapid dissolve tablet combines the potential pro-libido effects of PT-141 with the stimulating effects of caffeine, offering fast-acting support for sexual vitality. Designed for sublingual or buccal use, this formulation allows for convenient and rapid absorption.

Bremelanotide (PT-141)1,2

Bremelanotide (PT-141) is a melanocortin receptor (MCR) agonist. It is indicated for the treatment of premenopausal women with acquired, generalized hypoactive sexual desire disorder (HSDD), defined as low sexual desire causing significant distress or interpersonal difficulty and not attributable to:

  • A coexisting medical or psychiatric condition
  • Relationship-related issues or the effects of medications or other substances

Caffeine3-6

Caffeine, a xanthine derivative, is a central nervous system and respiratory stimulant. It exhibits vasodilatory effects and has been shown to increase mental alertness and arousal, aid in headache relief through vascular effects, and support respiratory function in neonates with apnea. Some studies also suggest caffeine may enhance genital blood flow.

Bremelanotide (PT-141)1,2

Bremelanotide, a MCR agonist, non-selectively works on several receptor subtypes MC1R-MC5R in the central nervous system. MC1R and MC4R are thought to be the most relevant. MC4R are commonly present in the central nervous system. This drug is thought to work by activating pathways in the brain that are involved in sexual responses.

Caffeine3-6

Caffeine is an adenosine-receptor antagonist that promotes inotropic effects in the heart and release of catecholamines to facilitate stimulatory effects. In the vasculature, caffeine promotes vasodilation through its ability to antagonize adenosine and stimulate endothelial cells to release nitric oxide. Through caffeine inhibition of adenosine receptors, the drug increases central respiratory drive and stimulates respiratory drive through its ability to increase pulmonary response to carbon dioxide in the medullary system.
