Sign in to saveTiagabine, sold under the brand name Gabitril, is an anticonvulsant medication which is used in the treatment of epilepsy. It is also used off-label in the treatment of insomnia and anxiety disorders. However, off-label use is discouraged as the drug has been associated with new-onset seizures in people without epilepsy. Tiagabine is taken orally.

Tiagabine, sold under the brand name Gabitril, is an anticonvulsant medication which is used in the treatment of epilepsy. It is also used off-label in the treatment of insomnia and anxiety disorders. However, off-label use is discouraged as the drug has been associated with new-onset seizures in people without epilepsy. Tiagabine is taken orally.
Side effects of tiagabine include dizziness, asthenia, non-specific nervousness, muscle tremors, diarrhea, depression, and emotional lability. The drug acts as a selective GABA transporter 1 (GAT-1) blocker or GABA reuptake inhibitor, and hence acts as an indirect GABA receptor agonist, increasing GABAergic signaling in the brain. It may increase activation of both GABAA and GABAB receptors. The effects of tiagabine on sleep resemble those of GABAA receptor agonists like gaboxadol and muscimol, primarily enhancing slow wave sleep, and differ from those of GABAA receptor positive allosteric modulators like benzodiazepines and Z drugs. The drug's elimination half-life is 4.5 to 9hours, but can be shorter in people taking enzyme-inducing anticonvulsants.
