Question 3

How does Lisdexamfetamine work?

Accepted Answer

Mechanism of Action

Lisdexamfetamine belongs to a class of medications known as central nervous system stimulants. It works by altering the levels of certain natural substances in the brain that affect hyperactivity and impulse control.

A Prodrug Delivery System

Lisdexamfetamine is unique because it is a prodrug. This means the medication is inactive when first taken. After it is swallowed and absorbed into the bloodstream, enzymes in the red blood cells convert it into dextroamphetamine, which is the active medicine. This conversion process happens gradually, which allows for a steady release of the active drug into the body over time.

Impact on Neurotransmitters

Once converted into its active form, the medication increases the activity of two specific chemical messengers in the brain:

Dopamine: A chemical associated with motivation, pleasure, and attention.

Norepinephrine: A chemical that helps the brain focus and respond to stimuli.

By boosting these chemicals, lisdexamfetamine helps improve focus, increase the ability to pay attention, and decrease impulsivity and hyperactivity in people with Attention Deficit Hyperactivity Disorder (ADHD). For those with Binge Eating Disorder (BED), the medication helps reduce the frequency of binge eating episodes, although the exact biological process for this specific effect is not fully known.
