MedKoo CAT#: 318867

CAS#: 145821-59-6 (HCl)

Description: Tiagabine is an anti-convulsive medication. The medication is also utilized in the treatment of panic disorder, as are a few other anticonvulsants. Tiagabine increases the level of gamma aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system by blocking the GABA transporter and hence is classified as a GABA reuptake inhibitor.
