One of the ingredients in Modalert 200 mg is modafinil, which improves brain performance by changing certain chemicals. Mostly, it changes the amounts of chemicals dopamine, histamine, and norepinephrine in the brain. These chemicals are important for controlling awareness, focus, and mental functions.

Dopamine levels are raised by Modalert, which makes people more motivated and alert. These are two important factors for better brain performance. A rise in norepinephrine levels improves focus and concentration, allowing for longer times of mental activity without the usual jitteriness that comes with stimulants. Histamine modulation also makes it easier to stay awake for longer periods of time and less likely to fall asleep.
