Modalert is known as a wake-promoting agent because it is a well-tolerated nootropic that treats excessive daytime sleep disorders. It is a prescribed and FDA-approved medication for treating narcolepsy, obstructive sleep apnea, and shift work disorder. The working of modafinil is that it increases the level of dopamine and histamine in the body, and these hormones alter the brain's chemical function and help the wake-sleep cycle. This is an effective and instant medication; within 30 minutes of its intake, it shows its action.
