Used as an active pharmaceutical ingredient in the treatment of epilepsy and anxiety disorders. It functions as a selective GABA reuptake inhibitor, enhancing inhibitory neurotransmission in the central nervous system. Due to its ability to cross the blood-brain barrier effectively, it is valuable in managing partial seizures. Also investigated for use in neuropathic pain and muscle spasticity due to its modulatory effect on GABAergic signaling. Its structural rigidity from the cyclopropane ring contributes to high receptor specificity and metabolic stability.
