Electro-oxidation of carbamazepine metabolites: Characterization and influence ...
Ginja Teixeira, Jorge; Veiga, Alfredina; Palace Carvalho, Alfredo J.; Martins Teixeira, DoraAbstract The electro-oxidation behavior of five important metabolites of carbamazepine (CBZ) and their potential influence on the voltammetric determination of the parent drug in biological fluids was investigated for the first time. This investigation was performed using cyclic voltammetry, in combination with controlled potential electrolysis and HPLC-DAD-MS analysis of oxidation products of these compounds....
