tiagabine profile

Tiagabine is a medication used to treat seizures. It is a selective inhibitor of the GABA transporter type 1 (GAT-1), which is responsible for the reuptake of GABA from the synaptic cleft. This results in an increase in the concentration of GABA in the synapse, leading to a reduction in neuronal excitability. Tiagabine was synthesized by researchers at the pharmaceutical company Pfizer in the 1980s. It was originally marketed under the brand name Gabitril. Tiagabine is a highly effective treatment for partial seizures, but it has several side effects, including dizziness, drowsiness, and fatigue. It is also associated with a risk of suicidal thoughts and behaviors. Due to these adverse effects, its use has declined in recent years. Tiagabine is still studied for its potential therapeutic benefits in other neurological disorders, such as epilepsy, anxiety, and pain.'

Tiagabine: A nipecotic acid derivative that acts as a GABA uptake inhibitor and anticonvulsant agent. It is used in the treatment of EPILEPSY, for refractory PARTIAL SEIZURES. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

tiagabine : A piperidinemonocarboxylic acid that is (R)-nipecotic acid in which the hydrogen attached to the nitrogen has been replaced by a 1,1-bis(3-methyl-2-thienyl)but-1-en-4-yl group. A GABA reuptake inhibitor, it is used (generally as the hydrochloride salt) for the treatment of epilepsy.

Role	Description
GABA reuptake inhibitor	A compound that inhibits the re-uptake of the neurotransmitter GABA from the synapse into the pre-synaptic neuron, so increasing the extracellular concentrations of the neurotransmitter and hence increasing neurotransmission.
anticonvulsant	A drug used to prevent seizures or reduce their severity.
