Bremelanotide (PT-141) is used to treat sexual dysfunction. Unlike other treatments for sexual dysfunction that influence blood supply, this treatment works directly on the central nervous system to stimulate sexual arousal, eliciting a more desirous sexual response. Its method of action leads to an increase in the levels of alpha-melanocyte stimulating hormone, a peptide involved in sexual arousal that may act as a neurotransmitter, or chemical signal for the nervous system. It is a safe and effective alternative to treat male or female sexual dysfunction and may help patients for whom Viagra, Cialis, or similar medications have failed.
PT-141 is prescribed to be administered subcutaneously by the patient 1-2 times per week.
