Gabitril
Tiagabine (IUPAC name 1-piperidine-3- carboxylic acid hydrochloride) is an anti-convulsive medication produced by Cephalon and marketed under the brand name Gabitril.
Though the exact mechanism by which tiagabine exerts its effect on the human body is unknown, it does appear to operate as a selective GABA reuptake inhibitor.
