Oral vigabatrin (VGB) effectively and safely treated poorly controlled epilepsy in a long-term study. Most patients experienced significant seizure reduction, with some becoming seizure-free.

Area of Science:

  • Neurology
  • Clinical Pharmacology

Background:

  • Epilepsy, particularly complex partial seizures, poses long-term management challenges.
  • Existing treatments may have limitations in efficacy or safety for poorly controlled cases.

Purpose of the Study:

  • To evaluate the long-term efficacy and safety of oral vigabatrin (VGB) as adjunctive therapy.
  • To assess VGB's impact on seizure frequency in patients with complex partial seizures.

Main Methods:

  • Single-blind, placebo-controlled, crossover trial involving 19 patients.
  • Treatment included 2 months of placebo followed by 13-15 months of VGB (1-4 g/day).

Main Results:

  • Significant overall decrease in seizure frequency observed.

  • Of 14 completers, 2 were seizure-free, 5 had >75% reduction, and 5 had >50% reduction.
  • Mild side effects did not lead to treatment discontinuation.

    • Conclusions:

    • Vigabatrin demonstrates remarkable efficacy and safety for long-term management of complex partial seizures.
    • VGB is a viable therapeutic option for patients with poorly controlled epilepsy.
