Treatment will call upon dopamine agonists, opioid medications, a benzodiazepine (clonazepam) that increases total sleep time, and drugs most commonly used as antiepileptic medication, such as gabapentin or equivalent. Dopamine agonists are the most effective and reduce the sleep deprivation and the patients complaints. But not all patients respond to dopamine agonists and methadone has been prescribed in the most refractory cases (21).

Pharmacologic treatment of RLS includes dopaminergic agents, benzodiazepines, opioids, or anticonvulsants. In mild cases of RLS, benzodiazepines may be first-line agents. Clonazepam, lorazepam, triazolam, and temazepam have been effective. Clonazepam 0.5 to 2 mg is most frequently studied. Opiates such as methadone 5 to 20 mg, codeine 30 to 120 mg, and oxycodone 2.5 mg are very effective, but the development of tolerance is a concern. Abuse potential with opiates is also a concern due to the chronic nature of the condition. Other agents that have been used include apomorphine, amantadine, tramadol, magnesium, oxycodone, propoxyphene, gabapentin, bromocriptine, clonidine, and carbamazepine. Tolerance may de-... 

Unlike other agents, which alter sodium or chloride flux, and which may have cross-re-activity with receptors for various neurotransmitters, gabapentin does not interact with sodium channels, nor does it influence receptors for benzodiazepines, opioids, catecholamines, or acetylcholine. 

Gabapentin has been reported to enhance the analgesic effects of morphine and other opioids. Morphine can increase the bioavailability of gabapentin. 

Observational studies The usefulness of gabapentin in combination with opioids in 24 Japanese patients with neuropathic cancer pain has been assessed in an open prospective study [155 ]. Gabapentin was added to opioid therapy in an initial dose of 200 mg/day titrated to a maximum dose of 2400 mg/day over 15 days. Gabapentin reduced the score on a pain scale, but the reduction was of minimal clinical benefit. Four patients withdrew because of adverse events headache, myoclonus, heartburn, and an attack of bronchial asthma). Only a few patients reported somnolence or dizziness, and these symptoms did not require drug withdrawal.
