Usage Basics

INN, Brand Names Available in Australia

The International Nonproprietary Name (INN) for flibanserin is, in fact, flibanserin itself. In Australia, it is available under the brand name Addyi. It is often manufactured in 100 mg oral tablets sold as film-coated options, which helps in ease of consumption. Users should note that the packaging may include additional branding but the active ingredient remains the same.

Legal Classification (TGA-Approved, PBS-Listed)

This medication is not currently approved by the Therapeutic Goods Administration (TGA) in Australia. Consequently, it is not registered for use nor is it listed on the Pharmaceutical Benefits Scheme (PBS). This means that flibanserin is not available through standard prescription avenues within the country.

Dosing Guide

Standard Regimens (PBS Reference Dosing)

The recommended standard dosage for flibanserin in managing Hypoactive Sexual Desire Disorder (HSDD) in premenopausal women is 100 mg, taken once daily at bedtime. This timing helps mitigate potential side effects such as hypotension or syncope, which may arise with daytime use.

Adjustments for Comorbidities

Caution is necessary when determining dosages for patients with hepatic or renal impairment:

• Hepatic Impairment: Flibanserin is contraindicated in individuals with moderate to severe liver impairment.

Patients should ensure that any online pharmacy is legitimate and follows Australian guidelines. Telehealth sessions can facilitate discussions about medications like flibanserin, ensuring patients receive an appropriate prescription in a timely manner and discover safe options for treatment.

Mechanism & Pharmacology

Simplified explanation

Flibanserin works by targeting the neurotransmitters in the brain to boost sexual desire. It differs from traditional male impotence medications that focus on blood flow. Instead, flibanserin enhances sexual appetite by modulating the balance of serotonin, dopamine, and norepinephrine. This unique mechanism makes it an appealing option for women facing HSDD. However, understanding its effects and how it contrasts with other medications is crucial for informed usage.

Clinical terms

Certain medical terminology underpins flibanserin’s mechanism of action. Key terms include:

• Neurotransmitters: Chemical messengers in the brain.
• Serotonin: A neurotransmitter linked to mood and desire.
• Dopamine: Often associated with pleasure and reward.
• Norepinephrine: Plays a role in arousal and alertness.
• Hypoactive Sexual Desire Disorder (HSDD): The condition flibanserin aims to treat.

Indications & Off-Label Uses

Approved indications by TGA

Flibanserin has been approved for treating hypoactive sexual desire disorder (HSDD) in premenopausal women by overseas regulatory bodies like the FDA. However, it currently remains unapproved by the Therapeutic Goods Administration (TGA) in Australia. This discrepancy impacts its availability and utilization within medical practice, leading to discussions around alternative therapies and mental health considerations in sexual desire issues.
