DEPAKOTE vs GABAPENTIN ENACARBIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases GABA levels by inhibiting GABA transaminase and succinic semialdehyde dehydrogenase; also blocks voltage-gated sodium channels and T-type calcium channels.
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 dose 750 mg/day PO in divided doses; increase by 250-500 mg/day every 3-7 days; maintenance dose 1000-2000 mg/day PO divided BID or TID; maximum 60 mg/kg/day.
Initial: 600 mg orally once daily; titrate to 600 mg three times daily; max 2400 mg/day divided three times daily.

Clinical Note
moderateGabapentin enacarbil + Venlafaxine
"The risk or severity of adverse effects can be increased when Gabapentin enacarbil is combined with Venlafaxine."
Clinical Note
moderateGabapentin enacarbil + Nefazodone
"The risk or severity of adverse effects can be increased when Gabapentin enacarbil is combined with Nefazodone."
Clinical Note
moderateGabapentin enacarbil + Stiripentol
"The risk or severity of adverse effects can be increased when Gabapentin enacarbil is combined with Stiripentol."
Clinical Note
moderateTerminal: 9-16 hours (mean 12 h); extended with hepatic dysfunction, co-administered enzyme inhibitors, or in elderly.
Terminal half-life of gabapentin: 5–7 hours in patients with normal renal function. Renal impairment prolongs half-life proportionally to creatinine clearance decline.
Renal: <3% as unchanged drug; >95% as metabolites (glucuronide conjugates, oxidation products). Biliary/fecal: minor, <5%.
Renal: 100% as unchanged gabapentin (prodrug is rapidly hydrolyzed to gabapentin after absorption). No biliary or fecal elimination of active drug.
