Abstract
The present invention is directed to compositions comprising a nanoparticulate modafinil compositions, or a salt(s), or an enantiomer(s), or a prodrug(s), or a polymorph(s) or derivative thereof, having improved bioavailability. The nanoparticulate modafinil composition formulation particles of the composition have an effective average particle size of less than about 2000 nm and are useful in the treatment of dyssomnias, including but not limited to, narcolepsy, chronic fatigue, eating disorders, compulsive behaviors, ADHD, addictions, substance abuse, sleepiness, nervous system diseases, conditions, syndromes, and symptoms and related diseases, conditions, and symptoms.
