Treatment for increasing sexual desire in women depends on the underlying cause of low libido

 Medications used to increase sexual desire in women generally target hormonal, neurological, or psychological factors that affect libido. Here are some common medications and treatments used to address low sexual desire in women, along with their mechanisms of action (MOA):

1. Flibanserin (Addyi)

• Indication: Used for premenopausal women with hypoactive sexual desire disorder (HSDD).
• Mechanism of Action (MOA):
  • Flibanserin acts on neurotransmitter systems in the brain. It is a serotonin 1A receptor agonist and a serotonin 2A receptor antagonist. By modulating these serotonin receptors, it increases levels of dopamine and norepinephrine, which are associated with sexual desire.
• Administration: Oral tablet, taken once daily at bedtime.
• Effectiveness: Studies have shown it can increase the number of satisfying sexual events and improve sexual desire.

2. Bremelanotide (Vyleesi)

• Indication: Approved for premenopausal women with HSDD.
• Mechanism of Action (MOA):
  • Bremelanotide is a melanocortin receptor agonist. It binds to the melanocortin receptors in the brain, which are involved in sexual arousal and desire. This action increases sexual desire and arousal.
• Administration: Subcutaneous injection, administered as needed about 45 minutes before anticipated sexual activity.
• Effectiveness: Helps to increase sexual desire and arousal, but its efficacy can vary among individuals.

3. Testosterone Therapy

• Indication: Considered for women with low libido associated with testosterone deficiency, particularly in postmenopausal women.
• Mechanism of Action (MOA):
  • Testosterone is a hormone that can influence sexual desire by affecting the central nervous system. It enhances libido through androgenic effects, which are mediated by androgen receptors in the brain and peripheral tissues.
• Administration:
  • Various forms including topical gels (e.g., AndroGel), patches (e.g., Testoderm), and injectable forms.
• Effectiveness: Improvement in sexual desire has been reported, though use in women is somewhat controversial and typically reserved for specific cases.

4. Estrogen Therapy

• Indication: Used in postmenopausal women experiencing low sexual desire related to vaginal dryness or discomfort.
• Mechanism of Action (MOA):
  • Estrogen helps maintain the health of the vaginal tissues and improves lubrication, which can indirectly enhance sexual desire by reducing discomfort during intercourse.
• Administration:
  • Can be administered topically (vaginal creams like Premarin), or systemically (oral tablets, patches).
• Effectiveness: Improved sexual function and reduced vaginal dryness can contribute to increased sexual desire.

5. Psychological and Behavioral Therapy

• Indication: For women where low sexual desire is related to psychological or relationship factors.
• Mechanism of Action (MOA):
  • While not a medication, therapy addresses underlying psychological issues, such as stress, anxiety, or relationship problems, which can improve sexual desire and function. Techniques such as cognitive-behavioral therapy (CBT) or couples therapy are commonly used.
• Effectiveness: Can be effective in improving sexual desire by resolving contributing psychological or relationship issues.

Flibanserin and bremelanotide are direct treatments for sexual desire, while testosterone and estrogen therapies are used for hormonal imbalances.
