Gabitril is an oral tablet made up of an anti-epileptic/anticonvulsant drug called tiagabine. This medication is available for purchase in 5mg, 10mg, and 15mg!

Gabitril (tiagabine) is prescribed with other medications to treat partial/focal seizures. All seizures are triggered by electrical disturbances located in the brain, partial/focal seizures occur when this disturbance remains in a limited section of the brain. These seizures can sometimes turn into a generalized seizure affecting the entire brain (secondary generalization).

Gabitril (tiagabine) is effective as a treatment for these seizures because it is able to reduce the spreading of the seizure activity in the brain.
