DRUG CLASS AND MECHANISM: Sibutramine is a medication that assists with weight-loss by altering neurotransmitters within the brain. Neurotransmitters are chemicals that are produced and released by nerves in order to communicate with other nerves. Released neurotransmitters may attach to other nerves or they may be taken up again by the nerves that release them, a process termed reuptake. Sibutramine blocks the reuptake of the neurotransmitters dopamine, norepinephrine, and serotonin. Blocking the reuptake of neurotransmitters alters the balance of neurotransmitters within the nerve cells and thereby affect nerve function and interaction.
