BREMELANOTIDE
THERAPEUTICS
Class
- Nonselective melanocortin receptor agonist
BREMELANOTIDE commonly prescribed for
(Bold for FDA approved)
How BREMELANOTIDE works
• Bremelanotide is a nonselective melanocortin receptor agonist; at therapeutic doses, bremelanotide binding to melanocortin 1 and 4 receptors is most relevant
• Sexual dysfunction is theoretically linked to an imbalance in central excitatory and inhibitory sexual signals
• HSDD hypothetically results from excessive inhibitory signals, inadequate excitatory signals, or a combination of the two
• Melanocortin receptors are located in the medial preoptic area of the hypothalamus, which is implicated in the sexual behavior of both sexes; stimulation of those receptors leads to dopamine release
How long until BREMELANOTIDE works
• Should be used at least 45 minutes before anticipated sexual activity; duration of efficacy after each dose is unknown and optimal window for bremelanotide administration has not been established

What to do about BREMELANOTIDE side effects
• Wait
• In most cases nausea improves after the first dose; for persistent or severe nausea, consider discontinuation or initiating antiemetic therapy
• For hyperpigmentation, consider discontinuation
• Switch to another treatment option
DOSING AND USE
usual dosage range
• 1.75 mg as needed, at least 45 minutes before anticipated sexual activity
Dosage Forms
• Subcutaneous injection 1.75 mg/0.3 mL in a single-dose autoinjector
long term use
• Safe and effective in controlled trials (24 weeks) and open-label extension studies lasting an additional 52 weeks
habit forming
• No
SPECIAL POPULATIONS
Renal Impairment
• Dose adjustment not necessary for mild to moderate impairment
• Use with caution in patients with severe impairment
Hepatic Impairment
• Dose adjustment not necessary for mild to moderate impairment
• Use with caution in patients with severe impairment
Cardiac Impairment
• Contraindicated
Elderly
• Not approved for use in postmenopausal women, and safety and efficacy have not been established
Children and Adolescents
• Safety and efficacy have not been established
Pregnancy
• Effective June 30, 2015, the FDA requires changes to the content and format of pregnancy and lactation information in prescription drug labels, including the elimination of the pregnancy letter categories; the Pregnancy and Lactation Labeling Rule (PLLR or final rule) applies only to prescription drugs and will be phased in gradually for drugs approved on or after June 30, 2001
• Controlled studies have not been conducted in pregnant women
• In clinical trials of up to 12 months, 7 pregnancies were reported; among these 7 pregnancies, no major congenital anomalies were reported; there was 1 spontaneous abortion (miscarriage), 5 fullterm live births, and 1 outcome unknown as it was lost to follow-up
• When administered to pregnant dogs during organogenesis, embryofetal toxicity occurred at doses approximately 16 times the maximum recommended human dose (MRHD)
• When administered to pregnant mice during pregnancy and lactation, developmental effects occurred at doses approximately 125 times the MRHD
• Advise patients to discontinue bremelanotide if pregnancy is suspected
• Pregnancy registry for bremelanotide: 1-877-411-2510
Breast Feeding
• Unknown if bremelanotide is secreted in human breast milk, but all psychotropics are assumed to be secreted in breast milk
• Bremelanotide is dosed episodically (average 2–3 times per month) and has a half-life of 2.7 hours
