Addyi (flibanserin) is the first FDA-approved medication to treat acquired, generalized hypoactive sexual desire disorder (HSDD) in premenopausal women. The exact mechanism of action of Addyi is unknown but it is believed to be associated with serotonin receptors (5-HT1A and 5-HT2A).

In animals, flibanserin increases dopamine and noradrenalin and decreases serotonin. Mechanism of action [edit | edit source] Flibanserin directly manipulates the chain of chemical reactions in the brain believed to trigger sexual desire.

At clinically relevant doses, flibanserin acts predominantly at 5-HT(1A) receptors as an agonist and secondarily at 5-HT(2A) receptors as an antagonist. Additional binding actions within an order of magnitude of its 5-HT(1A) affinity, which are not likely to be clinically relevant, include weaker antagonist actions at 5-HT(2C) and 5-HT(2B) receptors, and less defined activity at dopamine (DA) D4 receptors.

The proposed mechanism of action refers to the Kinsey dual control model of sexual response. Various neurotransmitters, sex steroids, and other hormones have important excitatory or inhibitory effects on the sexual response.

Mechanism of action of flibanserin, a multifunctional serotonin agonist and antagonist (MSAA), in hypoactive sexual desire disorder.

The proposed mechanism of action refers to the Kinsey dual control model of sexual response. Various neurotransmitters, sex steroids, and other hormones have important excitatory or inhibitory effects on the sexual response. Among neurotransmitters Reference Woodard, Nowak, Balon, Tancer and Diamond 5, Reference Arnow, Millheiser and Garrett 6 Thus, one can describe the hypothetical mechanism of action of flibanserin as stimulating postsynaptic 5HT1A receptors and blocking postsynaptic 5HT2A receptors in the prefrontal cortex, causing the downstream release of dopamine and norepinephrine and the reduction of serotonin in those brain circuits, thus regulating reward processing in premenopausal women with reduced sexual interest and desire. Flibanserin displays antidepressant-like activity in most animal models sensitive to antidepressants. Such activity, however, seems qualitatively different from that exerted by other antidepressants. Flibanserin seems to act via direct or indirect stimulation of 5-HT(1A), DA, and opioid receptors in those animal models. Flibanserin does not display consistent effects in animal models of anxiety and seems to exert potential antipsychotic effects.

CNS Spectr 2015;20:1-6. 13. The aim of this article is to review the hypothetical mechanism of action of flibanserin in HSDD. Methods. A literature review was conducted of all published works on flibanserin and on related studies of serotonin (5‐HT) 1A receptors and 5‐HT 2A receptors, including their actions on monoamines and on sexual function.

Description/Mechanism of Action The mechanism of flibanserin in the treatment of hypoactive sexual desire disorder (HSDD) is unknown. Flibanserin is a high affinity 5-hydroxytryptamine (HT) 1A agonist/5-HT 2A antagonist and a moderate antagonist of 5-HT 2B, 5-HT 2C, and dopamine D 4. Flibanserin was originally developed as

Do not take Addyi if you are allergic to flibanserin or any ingredients contained in this drug Flibanserin's approval by the FDA for women with hypoactive sexual desire disorder (HSDD), touted by the press as the "Pink Viagra," created an enormous amount of media hype across the nation. But the facts on this drug's mechanism of action, intended benefits, adverse effects, and efficacy borne in clinical trials have gone largely under the radar.

In this short piece, the human sexual response cycle and its relevance to HSDD will be described as well as the pharmacological mechanism of action of flibanserin. Finally, efficacy and safety data of this new medication will be summarised. PMID: 28434386 [Indexed for MEDLINE] Publication Types: Review; MeSH terms. Benzimidazoles/pharmacology* Female; Humans

As such, flibanserin has been described as a norepinephrine–dopamine disinhibitor (NDDI). The proposed mechanism of action refers to the Kinsey dual control model of sexual response. Various neurotransmitters, sex steroids, and other hormones have important excitatory or inhibitory effects on the sexual response. Among neurotransmitters Reference Woodard, Nowak, Balon, Tancer and Diamond 5, Reference Arnow, Millheiser and Garrett 6 Thus, one can describe the hypothetical mechanism of action of flibanserin as stimulating postsynaptic 5HT1A receptors and blocking postsynaptic 5HT2A receptors in the prefrontal cortex, causing the downstream release of dopamine and norepinephrine and the reduction of serotonin in those brain circuits, thus regulating reward processing in premenopausal women with reduced sexual interest and desire. Flibanserin displays antidepressant-like activity in most animal models sensitive to antidepressants. Such activity, however, seems qualitatively different from that exerted by other antidepressants.

In general, each monoamine is produced by discrete brainstem nuclei, which then … At clinically relevant doses, flibanserin acts predominantly at 5-HT(1A) receptors as an agonist and secondarily at 5-HT(2A) receptors as an antagonist.
