The present invention generally relates to compositions comprising anesthesia-reversing agents which facilitate or increase the time of awakening or reverse the effects of general anesthesia-induced unconsciousness. In some embodiments, the anesthesia reversing agent can be selected from any or a combination of methylphenidate (MPH), amphetamine, modafinil, amantadine, caffeine, or analogues or derivatives thereof. In some embodiments, compositions comprising at least one or more anesthesia-reversing agents can be used to facilitate awakening from anesthesia without or decreasing occurrence of delirium, and can be used in methods to treat or prevent the symptoms associated with emergence delirium, as well as treat a subject oversedated with general an esthesia. The invention also relates to methods for administering these compositions comprising anesthesia-reversing agents to subjects and for use.

The invention relates to a method for preparing a sulphoxide compound of formula (I) either as a single enantiomer or in an enantiomerically enriched form, comprising the steps of:a) contacting a pro-chiral sulphide of formula (II) with a metal chiral complex, a base and an oxidizing agent in an organic solvent; and optionallyb) isolating the obtained sulphoxide of formula (I);wherein n, Y, R1, R1a, R2 and R2a are as defined herein.

The present invention provides novel methods for the synthesis of racemic and enantiomers of modafinil via microbial oxidation-amidation transformation. The methods include the successive oxidation-amidation of benzhydrylsulfanyl carboxylic acid to produce racemic and enantiomers of modafinil using at least one microorganism of yeast, bacteria, or fungus. Also disclosed are pharmaceutical compositions of racemic and enantiomers of modafinil along with their use in the treatment of diseases, including attention deficit hyperactivity disorder and drug addiction.

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.

The present invention provides an improved process for preparing modafinil, whereby it may be isolated in high purity by a single crystallization. The process produces modafinil free of sulphone products of over-oxidation and other byproducts. The invention further provides new crystalline Forms II-VI of modafinil and processes for preparing them. Each of the new forms is differentiated by a unique powder X-ray diffraction pattern. The invention further provides pharmaceutical compositions containing novel modafinil Forms II-IV and VI.
