All analytical techniques have experienced major progress since the last ten years and
electroanalysis is also involved in this trend. The unique characteristics of phenomena occurring at the
electrode-solution interface along with the variety of electrochemical methods currently available
allow for a broad spectrum of applications. Potentiometric, conductometric, voltammetric and
amperometric methods are briefly reviewed with a critical view in terms of performance of the
developed instrumentation with special emphasis on pharmaceutical and biomedical applications.
Keywords: Biosensors, drug analysis, electroanalysis, pharmaceuticals, potentiometry, voltammetry.
