Bremelanotide: Uses, Dosage, Side Effects and More

Introduction: What is Bremelanotide?

Bremelanotide is a medication primarily used to treat hypoactive sexual desire disorder (HSDD) in premenopausal women. It is a synthetic peptide that acts on the melanocortin receptors in the brain, influencing sexual arousal and desire. Approved by the FDA in 2019, Bremelanotide offers a new option for women experiencing low sexual desire, which can significantly impact their quality of life and relationships.

Uses of Bremelanotide

Bremelanotide is specifically indicated for the treatment of HSDD in premenopausal women. HSDD is characterized by a persistent lack of sexual desire that causes marked distress or interpersonal difficulties. Bremelanotide is not intended for use in men or for enhancing sexual performance. Its approval provides a therapeutic option for women who have not responded adequately to other treatments or who prefer a nonhormonal approach.

How It Works

Bremelanotide works by activating melanocortin receptors in the brain, particularly the MC4 and MC3 receptors. These receptors play a crucial role in regulating sexual arousal and desire. By stimulating these receptors, Bremelanotide can enhance sexual desire and arousal, helping to alleviate the symptoms of HSDD. In simpler terms, it helps to "turn on" the brain's sexual response system, making it easier for women to feel interested in sexual activity.

Dosage and Administration

Bremelanotide is administered via subcutaneous injection. The standard dosage for adults is 1.75 mg, which can be injected into the thigh or abdomen. It is recommended to use Bremelanotide at least 45 minutes before anticipated sexual activity, and it should not be used more than once in a 24-hour period or more than eight times a month. There is currently no established dosage for pediatric patients, as Bremelanotide is not approved for use in individuals under 18 years of age.

Side Effects of Bremelanotide

Like all medications, Bremelanotide can cause side effects. Common side effects include:

• Nausea
• Headache
• Flushing (warmth, redness, or tingly feeling)
• Injection site reactions (pain, redness, or swelling)

Serious side effects may include:

• Increased blood pressure
• Allergic reactions (rash, itching, swelling)
• Changes in vision

Patients should contact their healthcare provider if they experience severe or persistent side effects.

Drug Interactions

Bremelanotide may interact with certain medications, particularly those that affect blood pressure. Major drug interactions include:

• Antihypertensive medications: Bremelanotide can increase blood pressure, so caution is advised when used with these drugs.
• Other medications that affect sexual function: Combining Bremelanotide with other treatments for sexual dysfunction may lead to unpredictable effects.

Always inform your healthcare provider about all medications and supplements you are taking to avoid potential interactions.

Benefits of Bremelanotide

Bremelanotide offers several clinical and practical advantages:

• Nonhormonal option: Unlike many treatments for HSDD, Bremelanotide does not involve hormones, making it suitable for women who prefer to avoid hormonal therapies.
• Quick onset: The medication can be administered shortly before sexual activity, allowing for spontaneous use.
• Improved sexual desire: Clinical studies have shown that Bremelanotide can significantly enhance sexual desire and satisfaction in women with HSDD.

Contraindications of Bremelanotide

Certain individuals should avoid using Bremelanotide, including:

• Pregnant or breastfeeding women: The safety of Bremelanotide during pregnancy and lactation has not been established.
• Individuals with uncontrolled high blood pressure: Bremelanotide can raise blood pressure, so it is contraindicated in those with hypertension that is not well-managed.
• Those with a history of allergic reactions: to Bremelanotide or any of its components.

Precautions and Warnings

Before using Bremelanotide, patients should discuss their medical history with their healthcare provider. Important precautions include:

• Blood pressure monitoring: Regular monitoring is advised, especially for those with a history of hypertension.
• Allergies: Patients should inform their doctor about any known allergies.
• Other medical conditions: Discuss any other health issues, particularly those related to cardiovascular health.
