Modafinil, marketed under the brand name Provigil, is a medication primarily prescribed to improve wakefulness in adults who experience excessive sleepiness due to certain sleep disorders. It is classified as a wakefulness-promoting agent. Approved by the U.S. Food and Drug Administration (FDA), its primary indications include narcolepsy, obstructive sleep apnea (OSA), and shift work sleep disorder (SWSD). While it promotes wakefulness, its pharmacological profile differs from traditional stimulants such as amphetamines. It is a controlled substance due to its potential for misuse and dependence.
