What are the serious side effects of Addyi?

It was originally developed as an antidepressant medication by Boehringer Ingelheim, but showed lack of efficacy in trials and was further developed as a hypoactive sexual disorder drug by Sprout Pharmaceuticals. Flibanserin's mechanism of action is attributed to its high affinity for 5-HTA1 and 5-HTA2 receptors, displaying agonist activity on 5-HTA1 and antagonist on 5-HTA2, resulting in lowering of serotonin in the brain as well as an effect on increasing norepinephrine and dopamine neurotransmitters. Flibansetrin has high affinity for serotonin receptors in the brain: it acts as an agonist on 5-HT1A and an antagonist on 5-HT2A. In vivo, flibanserin binds equally to 5-HT1A and 5-HT2A receptors. However, under higher levels of brain 5-HT (i.e., under stress), flibanserin may occupy 5-HT2A receptors in higher proportion than 5-HT(1A) receptors.

It may also moderately antagonize D4 (dopamine) receptors and 5-HT2B and 5-HTB2C. Its action on neurotransmitter receptors may contribute to reduction in serotonin levels and increase in dopamine and norepinephrine levels, all of which may play part in reward processing. Flibanserin is sold under the trade name Addyi and indicated for the treatment of premenopausal women with acquired, generalized hypoactive sexual desire disorder (HSDD) as characterized by low sexual desire that causes marked distress or interpersonal difficulty. Recommended dosage is 100 mg taken once daily at bedtime, discontinue treatment after 8 weeks if no improvement Curator's Comment: Flibanserin behaves as a 5-HT1A agonist in the cortex and hippo-campus of human and rat brain The concentration that reduces forskolin-induced cAMP formation by 50% in human hippocampus tissue was 4 nM. The United States Food and Drug Administration (FDA) approved the drug flibanserin (sold under the brand name Addyi) for the treatment of women with hypo-active sexual desire disorder (HSDD) in August 2015. Other serious adverse events were uncommon but flibanserin can’t be viewed as safe without further studies including a broader range of diverse women.
