For the treatment of adult Restless Legs Syndrome (RLS) and postherpetic neuralgia (PHN).


Since gabapentin enacarbil is a prodrug of gabapentin, it's physiological effects are the same as gabapentin. Concerning PHN, gabapentin prevents allodynia and hyperalgesia.

Mode of Action:

Although the exact mechanism of action of gabapentin in RLS and PHN is unknown, it is presumed to involve the descending noradrenergic system, resulting in the activation of spinal alpha2-adrenergic receptors.


Gabapentin enacarbil does not interact with any of the major cytochrome P450 enzymes.


Most common adverse reactions are headache, dizziness, and somnolence.
