Sibutramine
Sibutramine is really an appetite suppressant and was authorized by the FDA in 1997 to be utilized for an estimated two years in the treatment of obesity. It is marketed under the brand name of Meridia in the United States and as Reductil in other places.
Sibutramine works by inhibiting the reuptake of the catecholamine - norepinephrine, serotonin, and dopamine. While dopamine and norepinephrine (a precursor of epinephrine, aka adrenaline) improve blood pressure and fat burners best also the rate and depth of breathing, serotonin on the flip side carries signals of total satisfaction and create a relaxed mood.
The inhibition of the reuptake of these neurotransmitters by Sibutramine enables them to be for longer periods in the synapses - the gaps between nerve endings - so prolonging their power to function as transmitters of chemical signals. This contributes to improved amounts of the circulating portions of these neurotransmitters within the body which consequently causes you to feel satiated and energetic more for longer periods despite less food intake.
