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. Type Small Molecule Groups Approved, Investigational

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.

I noticed above that in the last couple sentences of the first paragraph under "Activity Profile" (subsection of "Mechanism of Action" section), the article states that the norepinephrine-dopamine disinhibitor (NDDI) activity of flibanserin is the result of its activation of the 5HT 1A receptor subtype. The fact that the doses of flibanserin that affected extracellular monoamine concentrations are in the range of those active in chronic mild stress and bulbectomized rat models of depression (Borsini et al., 1997; D'Aquila et al., 1997), and in the ultrasonic vocalization model of anxiety (Podhorna & Brown, 2000), suggests that the drug's action on monoamines may contribute to these effects. Objective/Rationale: Different mechanisms of action are considered relevant for provoking the involuntary abnormal jerking and hyperextensive or writhing-like twisting and turning movements called dyskinesias which appear after years of levodopa treatment and as Parkinson’s disease progresses. To find out whether a mechanism of action is of practical relevance, it is essential to test it in Flibanserin exposure increased 4.5-fold in patients with liver impairment, compared with those with normal liver function, increasing the risk of hypotension, syncope, and central nervous system depression; This medication contains flibanserin.

Benzimidazoles/pharmacology* Female; Humans This review summarizes the known preclinical data for this potential new HSDD treatment, and proposes a pharmacologic mechanism of therapeutic action for flibanserin in women patients with HSDD. Multifunctional Binding Properties: Flibanserin is a 5‐HT 1A Agonist/5‐HT 2A Antagonist Most therapeutic agents in psychopharmacology are multifunctional; that is, they have more than one pharmacologic action … Mechanism of action of flibanserin. Three monoamine neurotransmitters are of particular interest in considering the action of flibanserin: serotonin, norepinephrine, and dopamine. 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. 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 mechanism of action of flibanserin in the treatment of premenopausal women with hypoactive sexual desire disorder (HSDD) is not known; however, many neurotransmitters affect sexual response in women, and modulation of some of these neurotransmitters by flibanserin may contribute to its mechanism of action and efficacy.

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

The mechanism(s) of action by which flibanserin produces weight loss are currently unknown. The receptor binding affinity of flibanserin is highest for 5-HT 1A receptors (as an agonist) and 5-HT 2A receptors (as an antagonist).

Flibanserin displays antidepressant-like activity in most animal models sensitive to antidepressants.

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 has preferential affinity for serotonin 5-HT (1A), dopamine D (4k), and serotonin 5-HT (2A) receptors.
