It work by changing the activity of neurotransmitters in the brain, especially dopamine, norepinephrine, and serotonin. The ability to regulate your sleep and wake cycles depends on these chemicals. Although its exact mechanism of action is unknown, armodafinil is believed to stimulate dopamine release in the prefrontal cortex and hypothalamus, two areas of the brain. One of the important neurotransmitters is dopamine, which controls mood,motivation, and alertness.

This helps with wakefulness, focus, and mood control. Unlike most stimulants, armodafinil does not cause jitteriness and does not really mess up your sleep patterns. It is efficacious in addressing excessive daytime sleepiness associated with narcolepsy, obstructive sleep apnea (OSA), and shift work sleep disorder (SWSD).
