Answer

Anticonvulsants, Other

Anticonvulsants are being used more frequently for the treatment of moderate-to-severe RLS. They are particularly helpful in patients with a strong neuropathic symptom component or with comorbid neuropathy.

Gabapentin Enacarbil (Horizant)

A prodrug of gabapentin, gabapentin enacarbil, has been approved by the FDA. In a randomized, placebo-controlled study, 600 mg orally, taken once daily at 5 PM, provided sustained gabapentin exposure and maintained improvements in RLS symptoms in comparison with placebo. [29]

Gabapentin (Neurontin)

Gabapentin is indicated for patients whose symptoms include pain, neuropathy, or both. It may be used as a single treatment or with other treatments.

Pregabalin (Lyrica)

Pregabalin binds with high affinity to the alpha2-delta site (a calcium channel subunit). Its mechanism of action is unknown. In vitro, pregabalin reduces the calcium-dependent release of several neurotransmitters, possibly by modulating calcium channel function. This agent is FDA-approved for neuropathic pain associated with diabetic peripheral neuropathy or postherpetic neuralgia and as adjunctive therapy in partial-onset seizures. It is not FDA-approved for the treatment of RLS.
