Fliban 100 mg contains flibanserin, which is a medication used to treat hypoactive desire disorder (HSDD) in premenopausal women. HSDD is characterized by a persistent or recurrent lack of desire or interest in activity, which causes significant distress or interpersonal difficulty. Fliban 100 mg is specifically indicated for the treatment of acquired, generalized HSDD in premenopausal women who have not yet reached menopause. It is not approved for use in men or postmenopausal women. Flibanserin is a serotonin receptor agonist and antagonist that works on serotonin receptors in the brain. Its exact mechanism of action in the treatment of HSDD is not fully understood, but it is thought to modulate serotonin and other neurotransmitters involved in desire and arousal.
