Provigil 100 mg is indicated to improve wakefulness in adult patients with excessive sleep disorders like Narcolepsy, Shift Worker Sleep Disorder and Obstructive Sleep Apnea. For Obstructive Sleep Apnea, Provigil 100 mg is used to treat excessive sleep disorder and not as treatment for the underlying obstruction.
MECHANISM OF ACTION
The mechanism through which modafinil promotes wakefulness is unknown. Modafinil is not a direct or indirect-acting dopamine receptor agonist. However, it binds to the dopamine receptor and inhibits dopamine reuptake. It also raises the chemical norepinephrine in the brain to increase focus and alertness. It activates orexin cells which then release histamine to keep you awake.
