Abstract

The present invention provides a pharmaceutical composition, and provides for the use thereof for the treatment of excessive daytime sleepiness and/or a sleep disturbance in a psychiatric patient is need thereof. The pharmaceutical composition comprises a therapeutically effective amount of paliperidone, its pharmaceutically acceptable acid addition salts, enantiomeric forms, or esters thereof, together with a pharmaceutical carrier, and provides a relatively low plasma, concentration variation of paliperidone to the psychiatric patient in need of treatment. The present invention also provides for the use of a pharmaceutical composition as defined above for improving symptoms of schizophrenia in a psychiatric patient in need thereof, wherein the symptoms are selected from the group consisting of sleep disturbances and excessive daytime sleepiness.

This Invention relates to the ty~of p~liperid ' for the treatment of persistent sleep disturbances andlor excessive ~ ime'~ sleepin , in psychiatric patients.
Patients with mental illness ci~ ~ halve sleep °y.urbances including insomnia, and I
excessive sleeping. Sleep disturbances are common patients with schizophrenia, depression and bipolar disorders. rorie am~le, patie ' with schizophrenia appear to have lvnge~t sleep latency, a higher xty ber ~ f arou dwing sleep and increased periods of wakefulness after sle asset cons ~ ed Pith than ~1 non s chiatric control an s.

Additionally, the excessive sedation caused by souse ari syr~totic m I ations can result in impaired cogtitive functions and other sympto~7r ~th~t interfe. Nith successful treatment of the patient. More importantly, sedation c impair a pa , t's quality of life and efforts to lead a normal life. . I . .

'fhe initial dose of risperidone was 2 mg/day and titrated to 4mglday an Day 2. Because tho bioav,ailability of ER OROS
paliperidone is approximately 30% that of an oral solution ofpali,~erid.one, l2mg ER OR4S
paliperidone dose was selected to be administered as!an equivalent dose with.
respect to plasma levels to 4mg 1R risperidone. The >3R OROS ~aliperidone was provided as 2mg-tablets made substantially as described in Example 1.
Subjects in each group were given a once-daily oral dose, consisting of six (6) 2mg capsules, every morning daring the washout anc~ double-blind treatment periods.
Shady medication was administered sitting in att upright position with 200m1r, of water immediately after a standardized breakfast eaten. between approximately 8:00 a.m. and l0:0o a.m.
Study Evaluations Subjects were required to complete a washou~ period prior to participation in the study.

AlI meals during the study, including the vjr~ashout anal treatment periods, were standardized, consisting of a normal sodium diet with approximately 2,500 Kcal per 24 hours. The subject's total fluid intake was monitored and was not to exceed 3,000 mL

Pharmaculdnetic Evaluations At time points during the double-blind tree 'ent period. until the end of the study on Day 7, blood samples were obtained for measv ent of risperidone, paliperidone and active moiety concentrations in plasma. In each treafiient group, a venous blood sample of S nnl, was drawn to obtain about 2 tn 3mL o:f plasrj~a. The Collection schedule was as follows:

Effects ofpaliperidon~ ER on changes in. sleep architechtre (Dataset 1) were studied in patie~~.ts with schizophrenia~.relatad insomnia, and the clinical importance of these findings was further assessed by patient-rated changes in quality of sleep and daytime drowsiness (Dataset 2) in patients with schizophrenia.
