Carbamazepine is an early anticonvulsant still used today in the treatment of several forms of epilepsy. An active metabolite in the human body contributes to its pharmacological effect. Carbamazepine metabolism has high inter-individual variability, such that it is relatively difficult to establish a direct link between dose and concentration, or between concentration and pharmacological effect. Carbamazepine is thus a good candidate for therapeutic drug monitoring (TDM). Good UV specific absorbance and high plasmatic concentrations allow for the use of UV detection, which is often more accessible than other methods of detection. This paper presents several methods used for the detection of carbamazepine in plasma, methods that are capable of detecting drug and metabolites at adequate levels/ acceptance criteria. These methods have possible application not only in pharmacokinetic, bioequivalence, and permeability studies, but also in the therapeutic drug monitoring of carbamazepine.
