The anodic behaviour of carbamazepine (CBZ), an anticonvulsant drug, has been
studied on gold electrode in 0.1 mol dm-3 phosphate buffer of pH 7.0 by using
cyclic voltammetry. It has been found that the value of the oxidative current
of pure CBZ at +0.90 V is a linear function of the concentration in a range
from 1.0×10-7 to 1.0×10−4 mol dm−3. The detection of CBZ in the concentration
of 1.0×10-8 mol dm-3 is among the lowest that have been reported for this
drug using voltammetric techniques. CBZ as a content of tablet Galepsine® has
been quantitatively determined. It has also been demonstrated that the
modification of gold electrode with bovine serum albumin (BSA) results in a
decrease of the oxidative peak current due to the binding of the drug to BSA.
