A review of the effects of pregabalin on sleep disturbance across multiple clinical conditions.

Pregabalin is approved for the treatment of a variety of clinical conditions and its analgesic, anxiolytic and anticonvulsant properties are well documented. Pregabalin's effects on sleep, however, are less well known. This review summarizes the published data on the effects of pregabalin on sleep disturbance associated with neuropathic pain, fibromyalgia, restless legs syndrome, partial onset seizures and general anxiety disorder. The data demonstrate that pregabalin has a positive benefit on sleep disturbance associated with several different clinical conditions. Polysomnographic data reveal that pregabalin primarily affects sleep maintenance. The evidence indicates that pregabalin has a direct effect on sleep that is distinct from its analgesic, anxiolytic and anticonvulsant effects.
