Tiagabine [CAS: 115103-54-3] is an anticonvulsant primarily used as an adjunctive treatment for partial seizures in adult and pediatric patients. It combines with other antiepileptic medications to help control and manage panic attacks.
Tiagabine: Use and Commercial Availability
Tiagabine acts as an anticonvulsant for adjunctive treatment in partial seizures and, in some cases, epilepsy. The drug is associated with its capacity to enhance the activity of gamma-aminobutyric acid (GABA), the principal inhibitory neurotransmitter in the central nervous system.
Tiagabine is available under Gabitril, which contains the active ingredient, Tiagabine.
Tiagabine Structure and Mechanism of Action 
The chemical name of Tiagabine is (3R)-1-[4,4-Bis(3-methyl-2-thienyl)-3-buten-1-yl]-3-piperidinecarboxylic acid. Its chemical formula is C20H25NO2S2, and its molecular weight is approximately 375.6 g/mol.
Tiagabine inhibits the reuptake of GABA into presynaptic nerve terminals, enhancing GABA-ergic transmission.
Tiagabine Impurities and Synthesis
During Tiagabine preparation1, impurity formation is possible, compromising its effectiveness. They can arise from various sources, including the raw materials, intermediates, and chemicals utilized to synthesize Tiagabine. Close management and monitoring of impurities ensure the drug’s efficacy and safety.
Daicel offers a wholesome and integrated Certificate of Analysis (CoA) for Tiagabine impurity standards, such as Tiagabine diol analog, Tiagabine hydrochloride stage – I imp, and Tiagabine keto analog. The Certificate of Analysis (CoA) furnishes comprehensive characterization data, encompassing 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. Furthermore, we give a detailed 13C-DEPT analysis of product delivery. Leveraging advanced technology and expertise, Daicel Pharma can synthesize any unknown Tiagabine impurity or degradation product. We also offer labeled compounds to facilitate the quantification of generic Tiagabine efficacy. In bioanalytical research and BA/BE studies, we provide a deuterium-labeled Tiagabine standard, Tiagabine-D5 HCl.
