Mechanism of action

Sibutramine works primarily by inhibiting the reuptake of norepinephrine and serotonin in the hypothalamus and other brain regions involved in appetite regulation. This increases the availability of these neurotransmitters at synaptic sites, leading to enhanced feelings of fullness and decreased hunger. The drug also has a minor effect on dopamine reuptake inhibition.
