RT Journal Article SR Electronic T1 Modafinil in the treatment of excessive daytime sleepiness JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 561 OP 571 VO 74 IS 8 A1 Valentino, Roxanne M. A1 Foldvary-Schaefer, Nancy YR 2007 UL http://www.ccjm.org/content/74/8/561.abstract AB Modafinil (Provigil) is approved for treating excessive daytime sleepiness associated with narcolepsy, for shift-work sleep disorder, and as an adjunctive treatment in patients with obstructive sleep apnea syndrome who have residual daytime sleepiness despite optimal treatment with continuous positive airway pressure. Although modafinil improves measures of sleepiness, it does not generally normalize them, and it may be less effective than other stimulants for some narcoleptic patients. We need head-to-head comparisons of modafinil with traditional stimulants in humans to better define its role. We review the current approved and off-label uses of this drug and the evidence behind them.
