Modalert, which contains the active ingredient Modafinil, is a medication primarily used to treat excessive sleepiness associated with conditions like narcolepsy, obstructive sleep apnea, and shift work sleep disorder. Modafinil affects the brain's neurotransmitter systems, particularly those involving dopamine and norepinephrine. It increases the release of these neurotransmitters in certain brain areas, which helps improve wakefulness and alertness.

Unlike traditional stimulants that can increase heart rate and blood pressure, Modalert 200 Australia has a more selective effect on the brain systems involved in wakefulness.
