Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective enhancement of slow inactivation of voltage-gated sodium channels, stabilizing neuronal membranes and inhibiting excitatory neurotransmitter release.
Gabapentin enacarbil is a prodrug of gabapentin. It binds to the α2δ subunit of voltage-gated calcium channels, inhibiting calcium influx and reducing release of excitatory neurotransmitters such as glutamate, norepinephrine, and substance P. This modulates neuronal excitability and pain transmission.
Initial: 50 mg orally once daily; titrate at weekly intervals by 50 mg twice daily increments to maintenance dose of 200 mg twice daily (400 mg/day). Maximum: 400 mg twice daily (800 mg/day).
Initial: 600 mg orally once daily; titrate to 600 mg three times daily; max 2400 mg/day divided three times daily.

"The risk or severity of adverse effects can be increased when Gabapentin enacarbil is combined with Stiripentol."
Clinical Note
moderateTerminal elimination half-life ranges from 20 to 48 hours (mean ~32 hours). Steady-state achieved within 5-7 days.
Terminal half-life of gabapentin: 5–7 hours in patients with normal renal function. Renal impairment prolongs half-life proportionally to creatinine clearance decline.
Primarily eliminated by hepatic metabolism, with approximately 95% excreted as metabolites in urine and <2% as unchanged drug. Fecal excretion accounts for about 5%.
Renal: 100% as unchanged gabapentin (prodrug is rapidly hydrolyzed to gabapentin after absorption). No biliary or fecal elimination of active drug.
