Armodafinil 250 mg/1 (Armodafinil TABLET) 250 mg/1

Armodafinil is a central nervous system stimulant used to treat excessive daytime sleepiness in specific conditions.

• Narcolepsy: Improves wakefulness in patients with narcolepsy.
• Obstructive Sleep Apnea (OSA): Treats excessive daytime sleepiness in patients with OSA, but does not address the underlying obstruction.

• Armodafinil promotes wakefulness by enhancing hypothalamic orexin signaling and increasing extracellular dopamine. Its exact mechanism is not fully elucidated, but it is known to bind to the dopamine transporter and inhibit dopamine reuptake, similar to sympathomimetic agents like amphetamine and methylphenidate.
