Rapid initiation of gabapentin: a randomized, controlled trial.
OBJECTIVE
To compare the tolerability of two different dose-initiation regimens of gabapentin for the adjunctive treatment of partial seizures.


BACKGROUND
Patient compliance is a key feature of successful outpatient pharmacologic therapy for epilepsy, and one aspect of compliance is simplicity of initiation. By using a rapid titration rate, leading to a rapid therapeutic gabapentin dose, perhaps there could be an improvement with compliance.


METHODS
Male or female patients, at least 12 years old, with a recent history of partial seizures with or without secondary generalization, were randomized to receive gabapentin (following a blinded placebo period of an undisclosed number of days) as either a Slow initiation (300 mg day 1, 600 mg day 2, then 900 mg/day) or a Rapid initiation (900 mg/day immediately following the placebo lead-in).


RESULTS
Starting gabapentin therapy at an initial therapeutic dosage of 900 mg/day is well tolerated by patients with epilepsy and is as safe as initiating with a titration schedule over 3 days. Of the four most common adverse events (somnolence, dizziness, ataxia, fatigue), only one, dizziness, occurred more often in the nontitrated (Rapid initiation) group than in the titrated (Slow initiation) group.


CONCLUSIONS
Initiation of gabapentin at 900 mg/day is as well tolerated as is a 3-day titration, except for a higher incidence of dizziness.
