Reductil (sibutramine hydrochloride monohydrate) is an orally administered agent for the treatment of obesity.

Reductil is normally taken once a day in the morning.

This medicine contains the active ingredient sibutramine hydrochloride monohydrate, which is a type of anti-obesity medicine. It works by affecting neurotransmitters in the brain. Neurotransmitters are chemicals that are stored in nerve cells and are involved in transmitting messages between the nerve cells. They are released from nerve cells as a message is transmitted.

Once the message has been transmitted, the nerve cells then reabsorb the neurotransmitter. Sibutramine prevents two of these neurotransmitters, noradrenaline and serotonin, from being reabsorbed back into the nerve cells. This enhances the feeling of fulfillment from eating, and so makes you feel satisfied after eating less food.
