PT-141

PT-141, also published as Bremelanotide, is catalogued here as: Melanocortin receptor agonist. Bremelanotide is studied for sexual-desire endpoints in a defined population; receptor activity does not establish a broad performance benefit. PT-141 is bremelanotide, described as a melanocortin receptor agonist. An approved United States formulation exists with specific labelling; this listing is laboratory research material and is not that product. Also called bremelanotide, this peptide has clinical research on sexual desire in a specific female population using a defined drug formulation.

Research in this area examines melanocortin receptor signalling and sexual-desire endpoints in defined populations. Labelling for the approved formulation also documents adverse reactions and precautions.

United States labelling covers acquired, generalized hypoactive sexual desire disorder in premenopausal women, with stated exclusions, and notes that the mechanism for that indication is not fully known. Transient blood-pressure increases, nausea and hyperpigmentation are described among relevant considerations.

Official US label literature: The US indication is narrowly defined for acquired, generalized HSDD in premenopausal women; its mechanism for that indication is not fully known. The approved formulation is not this research material; US labelling is not Canadian authorization.

Official US label literature: The label reports nausea, transient blood-pressure increases and hyperpigmentation among safety considerations. The indication does not extend to performance enhancement, men or postmenopausal women.
