Fliban is a potent medicine that works on the brain. It specifically acts on three neurotransmitters dopamine, norepinephrine, and serotonin. These are also called brain chemicals. All these chemicals send messages from the brain to other parts of the body. Dopamine and norepinephrine are the two essential chemicals that help in sexual stimulation. While; serotonin works as an antagonist for sexual inhibition. Flibanserin active ingredient present in the Fliban has a unique mechanism of action. It has a high specificity for two receptors called 5-HT1A and 5-HT2A. This drug shows agonist activity on 5-HTA1 and antagonists on 5-HTA2. In short, it helps to reduce serotonin levels and increase the level of norepinephrine and dopamine neurotransmitters. This whole process finally leads to enhanced sexual excitement.
