A drug called armodafinil stimulates wakefulness by altering brain chemicals related to alertness and the sleep-wake cycle. It improves attention and lessens excessive daily drowsiness by increasing the activity of neurotransmitters like dopamine by blocking their reuptake. Additionally, it could have an impact on the arousal-regulating norepinephrine, histamine, and orexin pathways. These side effects make it a popular medication for narcolepsy, shift work sleep disorder, and exhaustion from sleep apnea. A brand of armodafinil with 150 mg is called Waklert 150. Although it improves alertness and focus, it does not treat underlying sleep problems and should only be used under a doctor's supervision.
