What is Flibanserin? Mechanism of action and pharmacological features

Flibanserin, often known by the trade name Addyi, is the first and only drug currently approved for the treatment of generalized hypoactive sexual desire disorder (HSDD) in premenopausal women. It is important to understand that Flibanserin works differently than erectile dysfunction drugs in men. It does not increase blood flow to the genitals, but rather affects neurotransmitters in the brain that are responsible for sexual desire.

The mechanism of action of Flibanserin in detail:

Multireceptor action Flibanserin acts as a 5-HT1A receptor agonist and 5-HT2A receptor antagonist in the central nervous system. These receptors play a key role in the regulation of mood, anxiety, and sexual function.
Effects on neurotransmitters: Flibanserin affects the balance of neurotransmitters, particularly serotonin, dopamine, and norepinephrine, in the prefrontal cortex of the brain. It is believed that the drug helps restore the balance between inhibitory (serotonin) and excitatory (dopamine, norepinephrine) neurotransmitters that affect sexual desire.
Increased Sexual Desire The exact mechanism by which Flibanserin increases sexual desire is not fully understood, but its effects on serotonin receptors and neurotransmitter balance are thought to play a key role in restoring sexual desire in women with ARDS.
Non-hormonal drug It is important to emphasize that Flibanserin is a non-hormonal drug and is not an analogue of testosterone or estrogen. It acts through the central nervous system, not through hormonal pathways.

Flibanserin is designed to be taken daily and its effects usually develop gradually over several weeks or even months. It is not a quick-fix pre-coital drug, but rather a long-term sexual desire modifier.

Indications for use: When can Flibanserin be useful?

Flibanserin is indicated for the treatment of:

Acquired Generalized Hypoactive Sexual Desire Disorder (GSDD) in premenopausal women: This is the only approved indication for the use of Flibanserin. GSDD is characterized by persistently decreased or absent sexual desire that causes significant distress or interpersonal difficulties for the woman. It is important that the GSDD is acquired (i.e., occurs after a period of normal sexual function) and generalized (i.e., is not limited to certain situations or partners). Flibanserin is intended for use in premenopausal women because its efficacy and safety have not been adequately studied in postmenopausal women or in men.

Flibanserin is not indicated for the treatment of low sexual desire due to other causes, such as:

Medical conditions (eg depression, anxiety disorders, endocrine diseases).
Side effects of other medications.
Relationship problems.
Psychological factors not related to ORSP.

Before starting treatment with Flibanserin, a thorough diagnostic evaluation is necessary to confirm the diagnosis of ARDS and exclude other possible causes of decreased sexual desire. The decision to prescribe Flibanserin should be made individually for each patient.

How to use Flibanserin correctly.

Correct use and dosage of Flibanserin are critical to achieving optimal results and minimizing the risk of side effects. Always follow your doctor’s recommendations and the instructions that come with the drug. Do not self-medicate or change the dosage without consulting your doctor.

Recommended dosage for the treatment of acute respiratory distress syndrome:

Recommended Dose: 100 mg orally taken once daily before bedtime. Flibanserin should be taken daily to achieve a lasting effect.
Timing of administration: Flibanserin should be taken daily, before bedtime. Taking the drug at other times of the day may increase the risk of dizziness, drowsiness, and other side effects associated with its sedative effects.
Food intake Flibanserin can be taken regardless of food intake. However, it should be taken into account that taking the drug with food may slow down its absorption.
Duration of treatment The effect of Flibanserin treatment usually develops gradually. The recommended period for assessing the effectiveness of treatment is 8 weeks. If after 8 weeks of treatment there is no improvement in sexual desire and a reduction in the associated distress, further treatment with Flibanserin is usually not recommended. The decision to continue treatment beyond 8 weeks is made by the doctor on an individual basis, depending on the clinical situation and the individual patient’s response to the drug.
Missed Dose: If you miss a dose of Flibanserin, do not take a double dose to make up for the missed dose. Skip the missed dose and take your next dose at your usual time before bedtime.

General recommendations for use:

Take flibanserin only as directed by your doctor.
Please read the instructions carefully before use.
Do not change the dosage on your own.
Take the medicine every day before bed.
Avoid drinking alcohol while taking Flibanserin.
Avoid concomitant use with certain medications, including strong CYP3A4 inhibitors.

If you have any questions or concerns about the use of Flibanserin, ask your doctor or pharmacist for clarification.

Contraindications: When Flibanserin Should Not Be Used

There are certain medical conditions and situations in which the use of Flibanserin is strictly contraindicated. It is important to familiarize yourself with these contraindications to avoid potentially serious side effects and complications. It is important to be honest with your doctor about any medical conditions you have before starting to take Flibanserin.

The main contraindications for the use of Flibanserin:

Concomitant use of alcohol: Drinking alcohol in any quantity during treatment with Flibanserin is absolutely contraindicated. The combination of Flibanserin and alcohol significantly increases the risk of serious side effects such as severe drowsiness, dizziness, fainting, and central nervous system depression. Patients taking Flibanserin should completely abstain from alcohol consumption.
Concomitant use with strong CYP3A4 inhibitors: Concomitant use of Flibanserin with strong CYP3A4 inhibitors is contraindicated as it may significantly increase the blood concentration of Flibanserin and increase the risk of serious side effects. Strong CYP3A4 inhibitors include, in particular:
- Antifungal drugs (eg, ketoconazole, itraconazole).
- Macrolide antibiotics (eg, erythromycin, clarithromycin).
- HIV protease inhibitors (eg, ritonavir, indinavir).
- Nefazodone.
The use of Flibanserin is contraindicated in women with liver failure of any severity, since the metabolism of the drug is significantly impaired in liver disease, which can lead to the accumulation of the drug in the body and an increased risk of side effects.
Concomitant use with moderate or weak CYP3A4 inhibitors when taken at high doses. These include, but are not limited to:
- Cimetidine.
- Cyclosporine.
- Verapamil.
- Diltiazem.
- Fluconazole.
- Grapefruit juice (large amount).
- Co-administration of these CYP3A4 inhibitors in large quantities with Flibanserin is not recommended due to potential increased side effects.
History:
- Hypotension or Fainting Women with hypotension (low blood pressure) or a history of fainting should avoid using Flibanserin because it may further lower blood pressure and increase the risk of fainting.

Before you start using Flibanserin, you should carefully evaluate all contraindications and inform your doctor if you have any of the listed conditions. Safety and your health are a priority.
