Gabapentin enacarbil is primarily used in the treatment of restless legs syndrome (RLS) and postherpetic neuralgia (PHN). For RLS, it helps alleviate the uncomfortable sensations and the urge to move the legs, particularly during periods of rest or inactivity, and improves sleep quality. In the case of PHN, it is effective in reducing the nerve pain that follows a shingles outbreak. As a prodrug of gabapentin, it offers better absorption and prolonged release in the body, providing sustained relief over time. It acts on the central nervous system to reduce pain signals and discomfort. It is typically administered orally and is often preferred for its improved pharmacokinetic profile compared to gabapentin, making it a more convenient option for patients requiring long-term management of these conditions.
