Is pregabalin effective for treatment of patients with restless leg syndrome?
['CONCLUSIONS: This study demonstrated improvements in objective and subjective measures of sleep maintenance and sleep architecture with pregabalin compared with placebo and pramipexole. Effects of pregabalin on periodic limb movement arousal index were comparable to pramipexole. ', 'CONCLUSIONS: Pregabalin provided significantly improved treatment outcomes as compared with placebo, and augmentation rates were significantly lower with pregabalin than with 0.5 mg of pramipexole.', 'The alpha-2-delta ligands, including gabapentin, gabapentin enacarbil, and pregabalin, are effective for RLS without known occurrence of augmentation or impulse control disorders, although sedation and dizziness can occur. ', 'Pregabalin has been established as effective for up to 1 year in treating RLS/WED (Level A evidence). ', 'In the group of anticonvulsants, only the trials performed with α₂δ ligands such as gabapentin, gabapentin enacarbil, and pregabalin showed good efficacy. ', 'Alternative or additional pharmacologic treatment with a lower level of overall quality of evidence includes opioids (codeine, tramadol, and oxycodone) and anticonvulsants (gabapentin, gabapentin enacarbil, and pregabalin). ', 'There is sufficient evidence to conclude that dopamine agonists such as rotigotine transdermal patch, pramipexole, ropinirole, gabapentin enacarbil, pregabalin and gabapentin are effective in the short-term treatment of RLS and rotigotine, followed by gabapentin enacarbil, ropinirole, pramipexole and gabapentin for long-term treatment.', 'Calcium channel alpha-2-delta ligands (gabapentin, gabapentin enacarbil, and pregabalin) provide alternative therapies for RLS especially in patients with augmentation, impulse control disorders, or hypersomnia induced by dopamine agonists. ', 'Alpha-2-delta ligands (gabapentin enacarbil, gabapentin, and pregabalin) increased the number of IRLS responders (RR=1.66; [95% CI: 1.33 to 2.09], k=3, high strength of evidence) and mean change in IRLS symptom scores (k=3, high strength of evidence). ', 'RECOMMENDATIONS: Level A recommendations can be made for rotigotine, ropinirole, pramipexole, gabapentin enacarbil, gabapentin and pregabalin, which are all considered effective for the short-term treatment for RLS.', 'Therapies with an OPTION level of recommendation include carbamazepine, gabapentin, pregabalin, clonidine, and for patients with low ferritin levels, iron supplementation.', 'CONCLUSIONS: In this 6-week phase 2b study, pregabalin reduced RLS symptoms in patients with moderate-to-severe idiopathic RLS', 'CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that pregabalin is effective for the treatment of restless legs syndrome and improves sleep architecture and periodic limb movements in placebo-unresponsive patients.', 'In severe, refractory or neuropathy-associated RLS, antiepileptic (gabapentin, pregabalin) or opioid (oxycodone, tramadol) drugs can be used.', 'The alpha-2-delta ligands, including gabapentin, gabapentin enacarbil, and pregabalin, are effective for RLS without known occurrence of augmentation or impulse control disorders, although sedation and dizziness can occur', 'This study provides Class II evidence that pregabalin is effective for the treatment of restless legs syndrome and improves sleep architecture and periodic limb movements in placebo-unresponsive patients.', 'Level A recommendations can be made for rotigotine, ropinirole, pramipexole, gabapentin enacarbil, gabapentin and pregabalin, which are all considered effective for the short-term treatment for RLS']
['Yes, numerous evidence from clinical trials indicate that pregabalic is effective for treatment of patients diagnosed with restless leg syndrome.']
